Mozilla Firefox ( American-English pronunciation [ moʊˈzɪlə ˈfaɪɹfɑks ]), or Firefox for short , is a free web browser from the Mozilla project . It was released in September 2002. According to StatCounter , Firefox was one of the three most widely used web browsers in July 2019, accounting for 8.82 percent of worldwide internet usage without mobile devices.

history

The Mozilla project Firefox, at that time still under the name Phoenix, was initiated by Dave Hyatt and Blake Ross as an experimental branch from the program package Mozilla Application Suite , which is based on the source code of the Netscape Communicator . The first executable version of the Phoenix 0.1 web browser was published on September 23, 2002.

In 2003 the developers of the Mozilla Application Suite decided to take a strategic turnaround. One of the reasons for this was Apple's decision to build its own Safari web browser on the KHTML renderer and not on the Gecko renderer developed by Mozilla.

While the Mozilla developers previously combined all the important Internet functions such as web browser, e-mail program, address book and HTML editor in a Mozilla Application Suite to reduce memory requirements , they now aimed to publish individual, independent components . The development was advanced in individual components. A lower memory and computing time requirement enabled a faster program start.

Firefox took over the web browser function . The e-mail function was outsourced under the name Thunderbird . The calendar was developed under the name Sunbird , which was discontinued in 2010 in favor of the Thunderbird extension Lightning . The HTML editor was further developed as Nvu until 2006 and as KompoZer until 2010 . The official Mozilla Application Suite 1.7 only received security updates. An independent programming group has been working on the further development of the application suite under the name SeaMonkey since mid-2005 .

With XULRunner there is a platform that contains the functions shared by Firefox, Thunderbird and other programs and is intended to reduce the required storage space and the size of the installation packages. This goal will not be pursued for the official release versions; instead, from Firefox 3 onwards, each application installs its own private XULRunner environment.

With the browser engine Quantum , which was renewed in November 2017 as part of Firefox 57, and the new user interface Photon , speed and memory consumption improved significantly. Add-ons based on XUL / XPCOM were no longer supported from this point in time.

Surname

Phoenix Logo (2002)
Firebird Logo (2003)
The red fox - the inspiration for the Firefox logo

Mozilla Firefox was originally developed under the name Phoenix , but this name had to be changed due to a lawsuit by the US BIOS manufacturer Phoenix Technologies . First the browser was renamed to Mozilla Firebird and finally - due to the fact that it had the same name as the open source database Firebird - with version 0.8 (February 9, 2004) to Mozilla Firefox .

Firefox is the literal English translation of the Chinese name huǒ hú 火狐  - "fire fox". So which is generally red fox ( red fox ), but also the red-brown little panda (red panda) called. Initially, the name was chosen without committing to either of the two animal species. However, in the eyes of designer Jon Hicks, the little panda had no particular visual appeal, which is why he was inspired by a Japanese red fox drawing subtitled “Firefox” when designing the logo.

Up to version 1.5 of Firefox, Fx or fx was named as the preferred abbreviation for the browser in the release notes; in later release notes this notice was omitted. However, the unofficial abbreviation FF is also used.

After a name dispute with the Debian project on the use conditions for the trademark of Mozilla included in the Debian distribution and slightly modified the Firefox version was named Iceweasel . Other Mozilla programs were also given new names, all of which began with Ice . These disputes were resolved in early 2016, and the Debian Project has returned to using the original names since then.

Functions and properties

Just like the Mozilla Application Suite, Firefox uses the Gecko renderer , a cross-program module for displaying HTML pages, and the XML- based description language XUL for designing the graphical user interface . Firefox may stop using XUL in the future.

Firefox can by motives ( English themes ) that can change the entire user interface, and personas which, although limited compared to the motifs in their features, but very easy to install and use, visually adapted to the tastes of the user. With extensions (English "add-ons") numerous functions, such as e. As mouse gestures , ad blocking and Web developers , add tools.

From version 0.9, Firefox contains a new standard motif called “Winstripe”, which replaces “Qute” as the standard motif, in order to give all versions of Firefox a uniform appearance, possibly adapted to the conditions of the respective platform. “Winstripe” is based on the “Pinstripe” motif used from version 0.8 under Mac OS X, which was developed by Kevin Gerich and Stephen Horlander with regard to Apple's specifications for the user interface Apple Human Interface Guidelines .

Firefox supports tabbed browsing , which means the display of several web pages , each provided with tabs , within a single application window. From version 4.0 it is possible to use the Panorama tabs function to group and display these groups visually. With version 45 this feature was removed due to low usage.

Originally, RSS - Web feeds in the form of dynamic bookmarks support. This feature was removed in version 64.0 for various reasons. These can still be viewed and subscribed to with the help of add-ons .

Firefox is currently offered in 86 languages, including German. The program is free software and is published under the GNU General Public License (GPL). From the point of view of the Mozilla Foundation , the GPL only applies to a limited extent to the compiled installation packages . Starting with version 3, when installing the browser, the user was asked to accept an end-user license agreement (EULA). After massive criticism of this approach, especially from the Linux camp, the EULA was replaced by a “Get to know your rights” information bar, which is displayed during the first installation. This can also be called up via the address line by entering about: rights .

Keywords (shortcuts) for searches can be defined to simplify searches using the address bar. The keyword search is a slight modification of the possibility to assign shortcuts / keywords to bookmarks.

An Easter Egg is built into Firefox . When about:mozillatyped in the address bar , The Book of Mozilla will appear .

Security and data protection

Warning message about a "website reported as attacking" in Firefox 15
Warning message about certificate error from Firefox 10.0.2

From version 3.5 Firefox offers a private mode in which no browser history or other data that accumulates while surfing is saved. Browser data generated in normal mode can subsequently be selectively removed using the "Delete recent history" function - either for a certain period of time or completely. Until the end of September 2017, this was not the case for data created with the IndexedDB interface. After public reports on this eight-year-old data protection problem, Mozilla changed this behavior in Firefox 56, so that databases created by websites can also be deleted subsequently.

In private mode, content is blocked that allows the user to be tracked across different websites. To do this, Firefox compares URLs with a list from the company Disconnect.Me .

A report is generated if the program crashes. Among other things, it contains the names of the installed add-ons and information about the system used (processor name, operating system used, etc.). The user can, however, suppress the information about the specific website. This report is intended for the developer to correct possible errors. Sending must be explicitly confirmed by the user.

To protect against phishing and malware , websites visited and the signatures of application programs downloaded by the user are automatically compared with a locally stored list of suspiciously reported pages and files from another manufacturer, by default Google, which is updated approximately every half hour.

Using a geolocation API implemented in JavaScript , websites can - with the permission of the user - determine the user's location via Firefox. A service from Google is used for this, which can evaluate and save the anonymous connection data.

Extensions

Firefox offers the possibility to install various extensions (English add-ons ) and "themes" in order to provide application functions or further options that are not offered by the actual browser, or to change its appearance. Some of these additional functions are deliberately not included in the range of functions of the browser, so that a relatively slim browser is retained and also to make the Firefox project clearer. Up until now, the extensions were files in ZIP format that contain programs written in XUL and JavaScript . The use of XUL and JavaScript makes these functions platform-independent. With Firefox 4 was a new add-on API (previously " Jetpack ") called interface introduced for extensions that exclusively to the web languages HTML , JavaScript and CSS based and should allow the installation and removal of extensions without a browser restart. With WebExtensions there is a new extension format from version 48 that is largely compatible with other browsers.

Marketplace

A platform called Firefox Marketplace was launched in October 2012 on which Firefox users can download applications for their browser. The marketplace was initially only available on Firefox for Android, but will later also be usable on other operating systems. Similar to the Chrome Web Store , all programs available there are based on web standards and are therefore not dependent on the respective architecture. Twitter and SoundCloud , among others, were available at the Firefox Marketplace to introduce them .

technical features

Firefox is currently available for the operating systems Windows (from Microsoft Windows 7 ), Linux and macOS (from version 10.9). Since Firefox 53, Windows XP and Windows Vista are only supported in the 52 ESR version (Extended Service Release). In January 2013, ESR 10 provided users of Windows 2000 and XP (SP2) with improvements to critical and security-relevant errors for the last time. Versions for Mac OS X 10.6 or higher are also offered as ESR. The Linux version also requires various third-party packages and libraries that are supplied with Firefox itself in the majority of distributions . According to the manufacturer, the recommended system requirements for Windows and Linux are an Intel Pentium 4 that supports SSE2 , 512  MB RAM and 200 MB hard disk space . Starting with Firefox 49, an SSE2-capable CPU is mandatory. The versions for Mac require an Intel x86 processor and also 512 MB RAM and 200 MB hard disk space.

Apart from the abovementioned officially supported by Mozilla versions are ports for Solaris (both x86 - and Sun SPARC - processors ), OS / 2 and AIX from IBM , FreeBSD , OpenBSD , PC-BSD , SkyOS , BeOS and ZETA and RISC OS . Porting to other platforms is possible due to the open source. A portable edition is now also available for use on external storage media ( e.g. external hard drives , USB sticks or memory cards ) for Windows. In addition, versions optimized for different platforms are available, which attempt to achieve faster response times and lower memory requirements. Mozilla has developed Firefox Mobile for smartphones , which runs on Android and iOS . Firefox for Fire TV , a version for use with Amazon Fire TV , has also been available since December 2017 .

In order to be able to use Mozilla Firefox better on Windows 8 tablets and other Windows 8 devices, Mozilla had also announced a Modern UI version, previously known as Metro . Like all apps for Windows 8, this should be optimized for touch screens . Due to the low public interest in Modern UI and thus in a version optimized for this surface and a small number of beta testers, development was discontinued and the project was canceled.

In an investigation into the support of the W3C standards (so-called recommendations), Firefox version 35 achieved a rate of 90% of the tested properties. For comparison: Safari 8 achieved 90% of the properties, 92% Google Chrome 40 as well as Opera 26 and 85% Internet Explorer 11.

history

In the past, after a new major version was released, the previous one was provided with updates for a while. In March 2010 with version 3.0.19 the support and further development of branch 3.0 and in April 2012 with version 3.6.28 that of branch 3.6 was discontinued and a new version cycle was introduced.

Since then, security and stability updates have only appeared in exceptional cases. Instead, the next major version with new or updated and changed functions was treated as a security and stability update at the same time. This approach aroused criticism, as it “is not reasonable for companies to switch to a new browser version every six weeks just to plug security leaks”. On the other hand, proponents of this approach saw advantages in the rapid supply of new functions and support for new web technologies, especially for home users.

In response to the criticism, Mozilla Corporation published a so-called Extended Support Release edition for companies, educational institutions and authorities at the beginning of 2012 with Version Firefox 10 ESR (German: Version with extended support). As before version 3.6, it did not contain any new functions, only bug and security updates. With every seventh main Firefox version - i.e. every 54 weeks - the previous ESR is replaced by a new version. So far, Firefox ESR versions 17 (end of 2012), 24 (autumn 2013), 31 (July 2014), 45 (April 2016), 52 (March 2017) and 60 (June 2018) have been released. At the beginning of September (2019), Firefox version 69 will follow, which should work without a Flash plug-in.

Portable edition

The official version of Mozilla Firefox normally requires an installation on the target system. However, this makes it more difficult to use removable media (for example with a USB stick ) across computers , which, among other things, enable Firefox with the same profile, i.e. the same bookmarks , history, form entries, passwords, settings and so on, to office and Use home computers. For this reason, PortableApps offers an unofficial, portable version of Firefox - Mozilla Firefox, Portable Edition - which has been adapted so that it can be unzipped directly onto a removable disk and can be used on this. The sensitive data remains on the removable storage device and does not have to remain on the local hard drive of the computer used.

64-bit variant

As early as 2009, there were 64-bit versions of Firefox for Linux created by Linux distributors .

In addition to the official 32-bit version of Firefox, Mozilla for Windows offered a 64-bit version of the Developer Edition for testing purposes . The first beta version of this variant was released with Firefox 38 on April 3, 2015. At the same time, projects such as Waterfox , Cyberfox or Pale Moon offered unofficial 64-bit versions generated from the Firefox source code.

Starting with version 42, Mozilla releases stable 64-bit versions of Firefox for Windows . Unlike the 32-bit variants, these no longer support NPAPI plugins - with the exception of Flash . Waterfox continues to support these plugins.

With version number 56.0.1, users of the 32-bit version of Firefox, provided their system has at least 2 GB of RAM, will automatically be switched to the 64-bit version. At the end of September 2017, around 70 percent of all Firefox installations on 64-bit Windows systems were 32-bit versions of Firefox.

Unofficial versions

Mozilla itself does not do any code optimization for specific processors. Like Mozilla Thunderbird , there are numerous unofficial versions (builds) for different operating systems of Mozilla Firefox .

One reason is the optimization for certain platforms (such as SSE2 builds for Pentium 4 processors). In combination with techniques such as profile-controlled optimization, which are supported by newer C ++ compilers, response times and memory requirements can be significantly improved, which in turn increases the speed of the browser. Nevertheless, the use of such unofficial versions is no guarantee for faster surfing, occasionally it even leads to a loss of speed.

criticism

In 2015, Mozilla adapted the Firefox browser for Windows 10 , which among other things offers an integrated Internet search. The search engine used by this function cannot be selected directly via the Windows settings. Mozilla has been criticized for converting this search engine as soon as Firefox is used as the standard browser and its own standard search engine deviates from the Windows preferred (and unchangeable search with Bing). The user cannot agree to this change or reject it, he is not even informed of this change.

In 2014, Mozilla was criticized for integrating support for Encrypted Media Extensions , copy protection for multimedia, into Firefox for Windows. Mozilla argued that this copy protection was used by many large streaming media services and that it was necessary to support it so that Firefox does not fall behind in comparison with other web browsers in which this support is already implemented. Critics pointed out that the implementation of copy protection uses source code that is not open source . This violates the principles of open source software.

The Mozilla Foundation has also been criticized for jeopardizing or having already given up on its previous ideals for large financial contributions from Google. (See also funding and advertising )

Older versions of Mozilla Firefox were criticized because they felt they had too high a demand for system resources . The developers stated that this behavior was partly intentional. From version 1.5 onwards, more open pages would be cached for faster navigation if sufficient resources were available on the system. However, this fact improved with newer versions of the browser. Version 3.0 was successfully optimized, among other things, to reduce resource consumption.

At the end of 2017, the bundling with the Cliqz add-on , which was initially included with one percent of Firefox downloads from Germany and activated by default, caused criticism from users . Possible restrictions on data protection were criticized, since the user inputs are sent to the servers of Cliqz GmbH, which mainly belongs to Hubert Burda Media , to display surfing suggestions when typing in the address bar .

In December 2017, the unsolicited installation of an add-on for US Firefox users to promote a US television series broadcast since 2015 caused criticism from users and prominent employees. This add-on had irritated some users because they thought it was a component installed secretly by malware . The critics saw this behavior as inconsistent with the goals of the Mozilla Foundation. Mozilla apologized and withdrew the automated installation of the add-on and, after an internal investigation, announced a month later changes to the so-called "shield studies" through which the add-on was installed.

According to a study by the French company AT Internet Institute , 35 percent of German surfers used Mozilla Firefox in March 2008. In Austria the browser was able to secure a share of 32.6 percent and in Switzerland a share of 26.4 percent. The front runners were Finland (45.9 percent), Poland (44 percent) and Slovenia (43.7 percent).

The German IT and telecommunications news portal Golem.de determined a market share of 58.3 percent among its readers in October 2009. According to the company, Golem.de's offer is primarily aimed at “ professional computer users ”, so the numbers are not representative.

The IT news service Heise online also has a disproportionately high proportion of alternative web browsers among its readers. In July 2007, more than half of Heise online readers preferred Mozilla Firefox for the first time.

In the German-speaking countries, Firefox was the most widely used browser from mid-2009. In April 2013 it held a market share of 39.3 percent in Germany and was ahead of Microsoft's Internet Explorer (22 percent). In Germany it was the most widely used web browser for several years until September 2016 (excluding mobile devices). In May 2017, according to StatCounter, it took second place behind Google Chrome with a market share of 32 percent . In October 2018, it ranks third behind Safari with a 15 percent market share.

In 2010 Firefox had a global market share of over 30 percent. Since then, the proportion has been falling continuously; in May 2015 it was 16.3 percent; in October 2018 this was 10.1 percent. In April 2019 the market share was 7%.

Download numbers

In order to promote the spread of the free Firefox browser and to be able to assert itself in the browser war , Mozilla organized several so-called “Download Days” with the aim of achieving as many downloads as possible in the shortest possible time. The project was able to outperform itself several times. In the course of the release of version 3.0, Mozilla called for “Download Day” in summer 2008 in order to set the world record for most software downloads within 24 hours. This goal was achieved with 8,002,530 downloads worldwide and included in the Guinness Book of Records .

When the first preview version of Firefox 1.0 was released in September 2004, Mozilla set itself the goal of achieving one million downloads in ten days; This succeeded after just four days. With the publication of the final version 1.0 in November 2004, this mark was broken on the first day. Almost six months later, on October 19, 2005, a total of 100 million downloads were counted. According to the manufacturer, version 2.0 was downloaded by over two million people within 24 hours of being released.

While the number of downloads for the release of version 1.0 still rose exponentially, it has since developed a rather linear course. By April 2010, over 1.3 billion downloads had been recorded.

User numbers

According to Mozilla's "Firefox Public Data Report", the number of active Firefox installations worldwide fell from 899 million in 2017 to 861 million in 2018; During the same period, the number of active installations in Germany rose from 71.7 to 75.7 million. The number of monthly active installations was 313 million in April 2017 and fell by 40 million to 270 million by April 2019.

Financing and Promotion

Firefox ad in the Frankfurter Allgemeine Zeitung

The Mozilla Foundation had annual revenues of $ 123 million in 2010, including approximately $ 100 million from a sponsorship deal with Google . In December 2011, the contract was extended to 2014. The annual payment is set at approximately $ 300 million. In return, Mozilla publishes its browser with Google as the default search engine. IT specialists from Google also helped develop Mozilla's web browsers.

For the official release of version 1.0, the US initiative Spread Firefox placed a double-page ad in the New York Times on December 16, 2004 , which was funded by donations. More than 10,000 people or families donated between $ 10 and $ 45 each within ten days, for which they were named in the ad. A total of $ 250,000 was raised.

In Germany, an appeal under the name “Firefox is coming” funded an advertising campaign through donations. The advertisement appeared on December 2, 2004 in the Frankfurter Allgemeine Zeitung and other national newspapers.

As of 2014, Mozilla tried to reduce its financial dependence on Google. At the beginning of 2014, Darren Herman announced that Firefox would display advertisements in the tiles in the future , but that they should be clearly marked. In mid-November 2014, the stable version of Firefox then displayed advertising in the tiles to existing users for the first time; this was the case earlier for users of the pre-release versions and new users. At the end of November 2014, Firefox's standard search engine was changed in the USA ( Yahoo ), Russia ( Yandex ) and China ( Baidu ) regions , including the corresponding contracts. While Google was still the default search engine for Europe in Firefox (and SeaMonkey) at the end of November 2015, CMO Denelle Dixon-Thayer said that there was currently no business relationship with Google. At the end of 2017, Mozilla ended the contract with Yahoo after or based on the takeover of Yahoo by Verizon. At the same time, a new contract was signed with Google.

Mozilla's revenue has grown steadily since 2005.
