Hello;

When Firefox is updating itself, it can create different profiles and so lose all bookmarks, passwords, logins and everything . And I have to start doing many things again, but can't return the pins I have kept or open tabs in other windows , and this cause me a lot already

I have 2 questions that I want answers for : 1 - Why you give a solution for this matter on your site ( https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update ) , and not solving this matter in the first place?

2- Are you going to fix this matter and when ?

Thank you.

Firefox just updated today and wiped all of my bookmarks and passwords. I need them to be restored as it included my login information for vital personal services such as my online banking, health information, etc. I hadn't saved this information anywhere else.

The passwords seem to have been stored in a login.json file, however, copying that file into my Firefox profile folder doesn't restore them.

Any help would be desperately appreciated.

Hello Mozilla team,

I recently received an update for the latest version of your browser and installed it. However, all of my bookmarks appear to be missing. I have an HTML backup of my bookmarks stored on a USB drive, but when I attempt to import it into the updated browser, I receive a message stating that the file is not recognized as a bookmark file and cannot be uploaded. This is unusual, as I am able to import the same HTML file on other computers and browsers without any issues.

I also tried using the “Sync” function to restore my bookmarks, but this did not work either.

Could you please advise on how I can resolve this issue?

Regards, James

This is the message I get when I try to access my Bookmarks: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I have already tried to find out from Microsoft if their latest reinstallation of Office Professional could have caused the problem. They say they have nothing to do with Firefox. How can I get my Bookmarks and History back?

I did reinstall of the Windows on all the devices I had, PC and laptop. Now I've lost my data bookmarks, password and sites. Please help me out how what I cab do here.

Several times now I've closed firefox while having the open previous windows and tabs on startup on only for all my tabs to have been closed (with this time in particular being annoying due to losing tabs that I needed to have the specific link for). Is there any way to restore tabs lost in this way?

your browser did an update on my windows 11 home version laptop and now I cannot access my bookmarks and have a message at the upper left side of my browser screen.....

Thanks, Scott

Firefox crashed with many open tabs. I went to History > Recently closed tabs > Reopen all tabs, clicked. Nothing. The list showing only very few of the tabs I had open, but none of them are restoring anyway.
