Hello, I have just installed Firefox version 144.0.2 on a new computer. I have access to all of the Firefox files and data on the original computer, but I am not able to run Firefox on that computer. Therefore, I am not able to create an export file from the original installation. Is it possible for me to import all of the original Firefox data into the new installation? Thank you very much in advance, Steve DeFeo

Can Firefox do anything to recover all of the downloads I'd saved until I accidentally had CCleaner erase everything? I don't know what else was deleted, but getting them back would be a big help.

Hello Team, today suddenly while restarting the PC, I did not close Firefox and restarted it. But when I opened it, a new Firefox appeared in front of me where Password bookmarks are nothing, how can I get them back?

Hello i have recently continued the windows 10 extended version and i cannot regain my bookmarks that use to be there. They are not in the back up or the restore options in the bookmarks tab. We have tried to solve this with articles off of the Mozilla website and we have not been able to regain the bookmark access.

I'm sure someone will have answered this somewhere but is there a way to backup and restore the native Mozilla Tab Groups. I've seen plenty of people recommend other Group Tab extensions but I like the inbuilt one combined with Containers.

I've read that you can backup the whole Mozilla profile folder and this should work but I've tried that and failed, I used a few extensions to backup sessions and that also failed.

Any help would be appreciated.

Due to the previous thread locked, I had to start a new threat but it continues from the previous.

When using the scrounger located here; https://www.jeffersonscher.com/ffu/scrounger.html. It creates a JSON file which can be renamed to as used in session profiles; sessionstore.jsonlz4. This is exactly what I've done then copied it to the new profile location: \Profiles\jj55ob2s.Default (release) and I don't see my tabs restored on a FireFox engine clone browser ?

For the third month in a row every, EVERY!!!, password I have saved to my Firefox browser have disappeared. Poof, GONE! For as long as I've used Firefox, 10-15 years, it had never happened before September of 25 Some of these password, prior to September, I'd had for years. Yes, I know I should change them over time, but I haven't. How do i recover them? I'm really Pi---d off. Help!

previously all the bookmarks were showing on the firefox left side , now all the bookmarks are gone . However when we are trying to import the bookmarks from other browser the option is not responding or working, So how can we get back those bookmarks?

Using Firefox on Mac (iOS 15.6.1) - restarted Firefox for updates and it's deleted ALL my bookmarks - what the hell? Everything gone from the toolbar, but I can still see them on my phone?

(This is the last straw of a string of bad experiences with Firefox - I think I'm switching to Chrome if there's no easy solution!)

A few days ago (today is November 9th 2025), my PC restarted itself while idling and when I got back, all my bookmarks in Firefox were just gone. The bookmarks toolbar, which I use constantly, was also gone. Furthermore, I can't even create new bookmarks. And I mean of ANY sort. Doesn't matter if click the little bookmark star when I'm on the page I want to save, or if I manually try to type it in by right-clicking the toolbar and choosing "Add bookmark..." None of it works!

I tried going to "Manage Bookmarks -> Import and Backup -> Restore" where I see 12 restore points. I've tried them all, but I get the same message every time: "Unable to process the backup file"

I've searched the Mozilla support articles and have only found one other entry from a person who seems to have had the same problem, here: https://support.mozilla.org/gl/questions/1504803

This person managed to solve it themselves by using the "Refresh Firefox" option, so I tried that, but it didn't work. The only thing I got out of it was losing all my extensions. I had been warned about that beforehand, so while it's a little more than just annoying that I've lost my Avast! Password Manager, which had a LOT of passwords I can't remember, not backing that up manually before running the refresh was entirely a brain fart on my own part.

Just to be sure, I've checked my Windows Update history to see if the culprit could be Windows rather than Firefox, but the last one was the 25H2 update that ran on October 17th. If that had been to blame, the problem would have manifested itself much earlier, so I'm fairly certain that has nothing to do with it.

So, two problems to solve here:

1. 1 - How do I fix this bookmark problem?
2. 2 - Is it perhaps possible to restore my Avast! Password Manager?

I would be VERY grateful if someone could help me with this! Like the person in the linked post, collecting these bookmarks has taken me over a decade and they've been used so frequently that - at least for some of them - I don't even remember the URL's of the sites anymore, because I literally haven't typed them in manually for years.

So this morning I sat down at my computer which was already on and working fine yesterday. Today my bookmarks had disappeared. I rebooted several times, closed and reopened firefox several times and I don't remember what else I clicked on but my bookmarks had reappeared. I sat down at the computer a while ago and opened firefox and my bookmarks seemed to have disappeared again. Before when I clicked on bookmarks up on the toolbar my bookmarks would appear. Now I have to click on bookmarks then bookmarks toolbar to see them and now all of my logins are gone. Should I just ditch this browser and use chrome or is there some simple fix? I never have had as many problems with a browser as I've had with firefox and I no longer see an advantage in using it.

Every once in a while, my pinned tabs and/or my tab groups disappear. this usually happens after an update, but not always. Sometimes I type a lot of commands, and FF seems to get upset and freezes or goes black. I restart and poof, they're gone. I made a screenshot of my standard pinned tabs so I can restore it from that, which is a nuisance in itself. But the tab groups are gone forever along with the urls I painstakingly researched. I read the answers to two previous queries along these lines, both of which gave extensive, tedious procedures to recover them. I'm not willing to go through all that just to use Firefox. I've switched my tab groups to Edge just to keep them safe and although I prefer not to be captured by Google or Microsoft, am thinking about just switching to either of them.

Over the last couple of updates, FF has seemed less and less stable. I tried the vertical tabs and liked them but the open sidebar on hover stopped working and when the sidebar itself got stuck on open it hid the history and AI sidebars. Plus FF was very slow to open. I reverted to horizontal tabs and now it's faster but still the pins and tab group problems persist.

I'm using it on an HP desktop in Windows 11. Sorry I don't have any screenshots.

Went to bed last night & firefox was fine.

Opened it this morning & I don't see my bookmarks. The folders on the toolbar from Africa to Healthcare all say empty. Lottery thru web cameras have links in them that I can see. I I open another tab & go to google, then save that bookmark in the google folder it won't let me yet edit bookmark shows.

If I click edit bookmark it tells me that it's in the google folder already yet when I click on the folder, it says empty..

Ran a virus scan. It was clean. I tried restoring bookmarks from a previous day. Firefox was unable to do it.

What is going on? If the bookmarks are there, why can't I see them?

I've used this browser for years without a problem. Now all the sudden it's one problem after another. I'm ready to jump ship to a different browser.

I'm on version 144.0.2 (64-bit) using Windows 11 Pro.
