Mozilla Firefox (or simply Firefox) is a free and open-source web browser developed by The Mozilla Foundation and its subsidiary, Mozilla Corporation. Firefox is available for Windows, macOS, Linux, BSD, illumos and Solaris operating systems. Its sibling, Firefox for Android, is also available. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. An additional version, Firefox for iOS, was released on November 12, 2015. Due to platform restrictions, it uses the WebKit layout engine instead of Gecko, as with all other iOS web browsers.
The Mozilla Firefox web browser claims to be currently 30% lighter than Google Chrome on Speedometer 2.0 benchmark — a modern way of evaluating web browser speed. Firefox also comes with tracking protection. Tracking Protection is a new privacy technology to mitigate invasive tracking of users’ online activity by blocking requests to tracking domains. We evaluate our approach and demonstrate a 67.5% reduction in the number of HTTP cookies set during a crawl of the Alexa top 200 news sites since Firefox does not download and render content from tracking domains. Tracking Protection also enjoys performance benefits of a 44% median reduction in page load time and 39% reduction in data usage in the Alexa top 200 news sites.
Firefox comes with lots of settings that can be adjusted from the menu. Over time you may wish to reset them to the default and go back to the way Firefox was originally designed instead of using it with the customizations you had added.
