The last stable releases for MacOS X 10.7 and 10.8 were: * Firefox 48.0.2, on August 24, 2016 * Firefox ''Extended Support Release'' 45.9.0, on April 19, 2017 If you don't need any of the features added in Firefox 46-48, then 45.9.0 is your best choice (most up-to-date). http://archive.mozilla.org/pub/firefox/releases/45.9.0esr/mac/ That lists all the available languages/locales. If you're not sure which one is the best fit, check the address bar when you're on this site and the auto-detected locale should be part of the URL (just after support.mozilla''.''org/). Please make a backup of your profile folder first before installing. These articles should help get you to the correct location: * [[Back up and restore information in Firefox profiles]] * [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]] Inside your profile folder, the '''bookmarkbackups''' folder has compressed backups of your bookmarks. If Firefox 45 couldn't read compressed backups, you can use a tool on my website to convert them to another format: https://www.jeffersonscher.com/res/bookbackreader.html

Wow that worked. Thank you so much
