I switched back to version 88. The "Upgrade" was intolerable. I need, want, and use daily the little icons at the top of the screen: The Open Book to show Side Bars to toggle my bookmarks into and out of view, and the Leaning Library books to manage my bookmarks. These were missing in the new version. And Firefox moderators kept turning of and archiving comments because they just didn't want to hear al the complaints.

I created this in a new account, because it sounded like a good idea when the question was asked (to preserve my existing settings). But now I don't have my previously open tabs. Can I get back to that previous "upgraded account to find my tabs and restore them to this new account in god old version 88?
