Diễn đàn hỗ trợ Firefox

The entire browser was acting extremely slowly, on every website, every start up. It crashed constantly to the point it was unusuable, it was even affecting the performance of the rest of my pc so I reset it and everything I had on the browser disappeared. Bookmarks, passwords, etc. I've tried going through the profile support pages but only the profile made from the reset exists. I had years worth of important bookmarks and passwords that'd I'd like to be able to get back if that's at all possible. (I'll live without them, it'll just suck trying to remember them all again) PC is Acer Aspire 3 Spin 14, Windows 10

100% of my bookmarks have disappeared. I tried backing up to older version a month ago and still no bookmarks were found. I had over 2000 bookmarks. any suggestions?? Marty

Firefox did an automatic update today. But now all of my saved bookmarks, saved passwords and items are gone in the new version. How can I retrieve them or return to my previous version of firefox?
