my firefox/mozilla updated without my knowledge. I turned the computer off and on and when it came back on it said it updated. My bookmark bar is missing along with all the drop down bookmarks I had..there was an arrow pointing down. I don't remember all of the bookmarks there were and there were lots. Some were for doctor portals. How can I get my bookmarks back I tried some online stuff but nothing works. Donna

After updating to the new version all of my open tabs & Bookmarks have disappeared with no option to recover. Additionally, all of my saved passwords for the various tabs I use daily no longer auto-generate with just a couple of clicks of the mouse.

Hello, All bookmarks disappeared after last update on Sunday 11.2.25. Is there a way to search some files and recover them? This is currently a big problem for me as all bookmark are related to our business.

I recently downloaded some Microsoft updates. When these were completed, and after restarting my computer, my Bookmarks & History were missing. I've attached a screen shot showing the error message. I've tried multiple links to recommended steps for correcting this, but nothing has worked. Do you have any suggestions?

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 recently installed a new add-on in Firefox — the one that allows you to create different profiles with individual names and colors in the browser.

After the installation and a subsequent restart of my MacBook Pro, my previously open session windows were not automatically restored when starting Firefox as usual. Instead, a message appeared asking whether I wanted to “restore all session windows.” I clicked “Yes,” but none of my previous windows opened.

Since then, my saved passwords and bookmarks also seem to have disappeared. I suspect that my previous profile may have been overwritten or that a new profile was created.

Could you please let me know if and how I can restore my previous sessions, bookmarks, and passwords? Is there perhaps a way to access my data through a backup or via the sessionstore.jsonlz4 file or an older Firefox profile?

Thank you very much in advance for your assistance.

Kind regards, Diamant Adler

When I started my browser today, my history and bookmarks were gone. When I try to restore them from the backup file, I cannot click on any buttons in the Manage Bookmarks folder. The buttons are entirely unresponsive.

Firefox has been going dormant (browser will not open), along with Task Manager and all Windows Admin Tools, whenever Windows 10 tells me it's time to update. I finally uninstalled Firefox and reinstalled, and now the browser opens, but all of my passwords and bookmarks are gone. I cannot find a "Profile" folder on my PC.

I recently had an issue with my computer screen. The computer itself worked fine, but the screen needed to be replaced. Stupidly, I went to the Bestbuy I bought it from to use the warranty for repair. They sent it out, I just got it back, and it says they replaced my motherboard for whatever reason. My downloads and such back up automatically, but because I didn't expect them to do something so drastic, I neglected to create a backup key for my tabs and bookmarks. Obviously, they're all gone now. Is there any way I could possibly get any of this back, or am I screwed out of luck because those morons made a drastic decision that did not need to be made? I'll apologize ahead of time for my lack of technical know-how.

Thanks

Launched this morning and the interface is totally different. That's not the problem All my bookmarks are gone and I'm unable to restore them

Can I move back to the previous version of FF?

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.

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.

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.

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.
