hello,

i attempted to update my Firefox this morning and the app froze and refused to reopen after multiple attempts. i decided to throw the app away and re-download firefox on my desktop, but now have no access to my bookmarks, open tabs (history) and passwords. please assist!

Hello, after a power cut I lost all my bookmarks. When I try "Manage Bookmarks -> Import and Backup -> Restore -> Choose File..." nothing happens.

In the folder ".mozilla/firefox/6924v31j.default-1728390329118/bookmarkbackups" there are several backup files, but the newest has the date Jun 25, though the name suggests it's from Jul 2: -rw-r--r-- 23850 Jun 25 13:07 'bookmarks-2025-07-02_184_mg1znof1NbBiyJ14ZcO9SluvTvLZI-rxPSm20YZUJww=.jsonlz4'

In the directory ".mozilla/firefox/6924v31j.default-1728390329118" there is also places.sqlite from Jul 4 11:59 (that was the moment when the power was cut).

How can I restore my bookmarks?

I did my monthly Norton 360 system scans and updates last night, and maybe it is coincidence, but all of my Firefox bookmarks are now missing, and there is no browsing History showing. I have tried the import/restore steps but each date I try to restore from I get an error message - "Unable to process the backup file".

Hey everyone!

So, I have an emergency issue...

I was using Firefox earlier today and for some reason, I don't remember why, but my computer had two "Firefoxes" at the same time—a closed one at its normal position on the dock and another "new" one that was opened to the right of the divider next to the trash can on the doc. It was probably some minor issue and I know sometimes my computer will open two of the same app simultaneously for games and stuff. However, here is where the issue begins. So, I, for some reason, moved the Firefox that was closed and at its normal position on the doc into the trash can and I moved the Firefox that was newly opened from the position right of the divider into the place where the original Firefox was. I then emptied the trash can. Later that day, I opened up Firefox as I usually would and went to check my saved tab groups and there was absolutely nothing there. I went on a few forums and listened to directions and input code into the Firefox console and still nothing turned up and nothing worked. It seems as though my extremely important and crucial saved tab groups are unrecoverable.

I would like to know what happened and how to recover my saved tab groups if possible. Thank you all for your help and taking time to read this message!

hey, I update my laptop windows, after updates when it restarted I have signed in to my account but bookmarks wasn't recovered. It was totally gone. I want my bookmarks back it is really important to me.

Why was my browser upgraded. Did you save my configuration before upgrading? How do I get my info back? I didn't set up a account with my previous account. I did setup a account with the new upgrade when I noticed all my passwords were gone. How do I get my info back

I only discovered the tab groups function within the last few weeks, and upon finding, I moved dozens of open tabs into organized groups. On using the feature, I noticed the ability to save and close groups and that I could recover those closed groups by using the arrow in the browser toolbar.

When I got to my PC this morning, my desktop had restarted or hibernated or something; when I started it up, Firefox was open which is unusual as I don't have Firefox set to open on startup - usually so I can restore sessions after crashes. All of my previously open tabs were open, but none of the closed, saved tab groups are visible. I cannot find any of the dozen or so closed tab groups and it appears I've lost easily hundreds of tabs.

I tried looking at the session backups but it seems because Firefox was open on start, it overwrote the previous session data. Is there any way to recover those saved groups or am I SOL?

The recent update has basically wiped out my Firefox information and set-up. I have a lot of critical links set-up in my new tab. It is imperative I get them all back please. This is terrible for me.

I have already done the about:profiles, made new profile, used the file named old Firefox files (dated 03-25-25) but end up with the same crap coming up. How is this possible?

PLEASE help.
