Firefox crash and data loss, presumably after Windows update
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?
Chosen solution
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.
- Do NOT click any Remove button on this page.

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!
