After restarting my pc, signed in on another windows account, which does not have Firefox installed. Then, signed in to my account, opened Firefox (Developer Edition 112.0b9 (64-bit)), however, all of the tabs, pinned tabs and history were gone. Can't restore from the menu, can't restore from the Profile folder, because files in it were overwritten when I signed in to my account (according to time modified). Anybody been in the same situation? Any advice? Thx

Sorry about my previous answer, this was meant for another thread.

Does this work properly if you disconnect Sync ? Are there other tabs connected to this Sync account?


In case you use "Clear history when Firefox closes".

  • do not clear the "Browsing history"
  • using "Clear history when Firefox closes" in Firefox 102+ honors exceptions and keeps cookies with an allow exception, previous versions removed all cookies
  • clearing "Site settings" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
