items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

I just transferred my data from an old computer with Windows 10 and now have Windows 11 on my new computer with a new version of firefox as my browser. How do I restore my bookmarks?

I've lost everything in bookmarks. The toolbar. The general bookmarks. Everything. Could this be because I tried to download Claude on my new mac mini. Help please. We only use firefox. All the time!

This keeps happening and is getting worse every day.

Firefox is refusing to load tabs sometimes every few hours but recently every few minutes so I have to shut it down and restart it, sometimes when I do I lose all my pinned and non pinned tabs, I can't remember what they are so manually restoring them doesn't work.

There should be a way to backup all tabs so they can be restored when this happens.

FIX IT FFS.

OS: Linux Mint Latest update of Firefox

Hi, is there a way mozila can help me to retrieve all my remember login ID and password? due to i changing to new laptop and when i sign out it ask me to delete all the old password which i thought is just delete from the laptop instead of my whole login ID and password.

My computer ran into an error and restarted and I lost my entire browsing history, bookmarks, extensions, etc. Now I have nothing saved and the only browsing history my computer is showing is when I briefly opened microsoft edge. I regularly used duckduckgo, so most of my data is gone. Is there anything that can be done or is it just gone.

Hey guys, My friend got on my pc and shut it off without me looking and somehow when i opened it back up all my tabs(couple hundred) distributed between 3 windows were lost. I've tried all the usual recovery options by doing previous or session restore, its not popping up in recently closed windows as well, where i usually recover my sessions from if it does go wrong. Is there any other way where this data may be stored, to recover a session from 31st Dec 2025.

Would greatly appreciate any help :D

I opened my computer several days ago. Firefox updated itself sometime recently while my laptop was closed. Once I opened it, it made me create a profile to continue. Now ALL of my history is deleted. All of my windows and tabs are gone. There is no history beyond the profile it made me create to continue using it. Is there any way to get back the previous history? This is about enough to make me give up on firefox completely.
