Switch to Firefox Extended Support Release (ESR) for personal use

Firefox Extended Support Release (ESR) is an official version of Firefox developed for large organizations like universities and businesses that need to set up and maintain Firefox on a large scale. Firefox ESR does not come with the latest features but it has the latest security and stability fixes.

Warning: By default, different versions of Firefox will use the same user profile data. Data loss or other problems can occur if the Firefox ESR version you install is lower than the Firefox version you are currently using. If you experience problems, try refreshing Firefox. See Refresh Firefox - reset add-ons and settings for details.

You can download Firefox Extended Support Release for your operating system and language from the Firefox ESR download page.
