I have an mid 2007 IMac running El Capitan 10.11.6 I replaced my old Firefox version with a newer incompatible one and now I can’t recover the old version of Firefox. All my bookmarks and saved data was on that older version. Can anyone help me find the most current version of Firefox for my Mac? Thanks!
