Adobe Systems is going to end support for the popular Flash technology once and for all at the end of this year, and browser developers have been preparing for this historic moment for several years, gradually cutting support for the standard. Mozilla recently announced when it will take the final step towards abandoning Flash in Firefox to increase security.
Mozilla will permanently get rid of Flash in Firefox 84
Support for Flash technology will be completely removed in Firefox 84, which is scheduled for launch in December 2020. This browser version will no longer be able to run Flash content. Mozilla Firefox currently ships with Flash disabled by default, but users can manually enable the extension if necessary.
Needless to say, turning Flash on is not recommended, but still, not all sites have switched to HTML5. In the near future, Mozilla will continue on the path of abandoning Flash in Firefox. The next important step will be in October. The company will disable the extension in the early Nightly build of its browser.
This is logical because Mozilla always makes major changes to Firefox first in Nightly builds. After this, it rolls them in beta to make sure everything works well. After completing the testing process in these early builds, Mozilla is already making changes to the final versions of its browser. Needless to say, Mozilla is not the only company that refuses Flash. In browsers based on the Chromium engine, the same thing happens. As in the case of Firefox, everything happens in stages, so it will take a few more months until Flash disappears from all current browsers forever.
Adobe already announced in July 2017 that it would bury the Adobe Flash Player at the end of 2020. At the same time, Mozilla had announced that support for Adobe Flash Player in Firefox would end in early 2020 for private users and in late 2020 for enterprise users.
