The speed with which websites are loaded, and resource use, have also seen improvements, therefore avoiding the excessive use of memory found on previous versions. Performance and stability have, once again, been improved with better JavaScript and rendering engines, increased HTML5 compatibility, independent processing for the browser’s add-ons, and much more. Its latest releases have centered on improving technical aspects, as its appearance continues being pretty much the same as that of previous versions. Among its main features are the option of being able to browse several websites at the same time thanks to its tab system, all while supporting most existing web standards as well as offering a personalized experience thanks to its extensions, add-ons, and themes that have been created by the community and which allow you to expand its functions. Mozilla continues working on more improvements for its star product: the free and open source browser, Firefox.
