Firefox Klar is a web browser from the Mozilla project for users of Android and Apple's iOS mobile devices and at the same time a tracking blocker for the Apple Safari web browser . While this is known as Firefox Klar in Germany , Austria and Switzerland , it is known internationally as Firefox Focus . The app was originally developed as a pure ad blocker for the iOS operating system and released in 2015. The expansion to an independent web browser followed shortly thereafter. The first version for Android was released in June 2017 and downloaded over a million times in the first month. It is available in 27 languages. Firefox Klar has been preinstalled on the Blackberry Key2 as part of the Locker application since July 2018 .

Functionality

The web browser, which is designed for simplicity and privacy protection, can also function in the background as a content blocker for the Apple Safari web browser to prevent advertising and analysis tracking as well as potentially unwanted tracking by social networks. When using the app as a browser, all loaded session data can be deleted from websites at any time with a remove button. This also closes all open pages and calls up the Firefox Klar start page, which is equipped with a search field. The search engine used there is freely selectable and can be individualized by entering a URL.

In contrast to desktop Firefox and Firefox Mobile , ad tracker blocking is enabled by default.

Firefox Klar Settings

The activated blocking of advertising content results in faster loading times when visiting websites. At the same time, the consumption of the mobile data volume is reduced . To bypass content blocker restrictions on the part of Apple, the UIWebView API is used in Firefox Klar .

The function of bookmarks can be replaced by website links that can be created directly on the device's home screen. Additional tabs can be opened with a long click on links. A personally adaptable autocomplete function suggests a complete URL when typing a letter in the address line in order to make it easy for the user to access websites.

In version 6 the browser was extended to include a page search. The desktop version of a page can now also be called up, if available. Both functions can be called up from the menu.

renaming

On January 25, 2016, Mozilla announced in the press blog that the Firefox Focus web browser would be referred to as Firefox Klar in German-speaking countries. This is justified by the fact that the publishing and media group Burda , which owns the magazine Focus , is a partner of Mozilla.

System requirements

Apple iOS devices

Filtering out advertisements and trackers is computationally intensive and therefore only possible on 64-bit devices with iOS 9 and higher, for example with:

• iPhone 5s and newer
• iPad Air and newer
• iPad mini 2 and newer
• iPod touch from the 6th generation

Android devices

To use the current version of Firefox Klar, Android version 5.0 or higher is required.
