Firefox crash and data loss, presumably after Windows update

Skrevet

My laptop did a Windows update, Firefox worked ok, even opened the last session before update, but suddendly it crashed and next time I opened it, all personal profil data was gone. I can't find any of my personal settings either in Firefox nor in AppData either. Bookmarks, add-ons, all gone. Any chance to recover them and where?! And how come this occurred in the first place?

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

Hi mirta.surlina,

Something must've happened to your Firefox profile data, could you check that out using this: Profiles - Where Firefox stores your bookmarks, passwords and other user data

Let me know what you find.

Thanks a ton, the default profile was the issue! I wasn't aware this could've happened.... thanks again!
