I have used firefox for 3 or 4 years, today it would not open. I had to reinstall and start over from the beginning. I lost a lot of bookmarks and preferences.

Posted

Adobe installed an update, which restarted my desktop pc. After restarting I was unable to open Firefox browser. So, I clicked on Firefox, and then run as... first I tried running as... and chose my name. Firefox browser still would not open. Then I chose administrator which opened Firefox browser, but, as a new Firefox installation. It did contain add-ons, but not book marks, history, downloads or preferences. Now i have started over from the beginning. Is there any way I can restore lost bookmarks and preferences? Do you think system restore would help?

Are there still JSON backups in the bookmarkbackups folder?
