This version has also improved the loading speed for sites and resource consumption to avoid excessive memory usage like previous versions. Firefox has improved its performance and stability with optimized JavaScript engines and rendering, greater compatibility with HTML5, independent processes for browser plug-ins, and more.

The latest installment is focused on improving its technical aspects, so the appearance is almost the same as in previous versions. Its many features include enabling the simultaneous browsing of multiple pages with its tab system, supporting most existing web standards, and offering a personalized experience with extensions, plugins, and themes created by the community. Mozilla continues to work on further improvements for its flagship product: the free and open-source browser, Firefox.
