firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

After Firefox requested to be updated, I lost all of my bookmarks. I tried to go in and "restore" them but there are no backups to restore from. How do I get my bookmarks back?

My Firefox Updated today and just closed randomly, on reopen it was brand new with no history/bookmark etc. I didn't have a firefox account at the time. Is there a way to restore it since i used a lot of mozilla auto set passwords which have also been deleted.

I recently installed Firefox for security reasons, but I now realize it might be not better than other browsers... I had a (good) number of tabs opened in 12 Simple Tab Groups, which were opening all right everytime I restarted my computer. But today, Firefox opened and oh, all my tabs have disappeared ! All 12 Simple Tab Groups are empty. In the Recently Closed Tabs in History, I only could find and reopen 26 tabs - a very small part of the tabs I had... Please, tell me if there is a solution to recover all my tabs. Is the problem with Firefox or with the Simple Tab extension?

I was working away on copying some files, nothing to do with Firefox. Firefox was open, though I hadn't used it in several minutes. Upon returning to Firefox, I noticed that although my browser had been open, it was not open anymore. All that was open was the download window.

At times in the past, I've accidentally closed the browser window while the download window was still open. I thought maybe this was what had happened this time, even though I absolutely didn't do that. I closed the download window and clicked on the icon on my desktop to restart it.

And that was when I discovered...no more tabs. Not a single one. Just a plain single blank tab.

In searching for an answer, I found this page: https://support.mozilla.org/en-US/questions/1396868 but in my confusion and horror and anxiety over needing to get the tabs restored, I had missed this part: "Assuming you found the .html file, it should indicate which .jsonlz4 file it was listing out. Is that the file you want to roll back to (the .jsonlz4 file, not the HTML file)?" and I had started to follow the procedure below it, and after renaming the two files as specified, I realized...I don't have a file to restore.

And so now I have nothing. I don't know how to restore my tabs at all. I literally have no access to anything, because all was tied up in those tabs. How do I restore them? I did find another procedure elsewhere that used "History" and "Restore previous session," but the problem with that solution is that in the "History" there's no such option at all. (This is where I found that one.) https://www.bleepingworld.com/restore-previous-session-firefox/

I'm so afraid to try anything now, I haven't had this problem in years and now I'm totally lost and afraid to mess this up more.

As for the browser I'm writing about, it's the latest Firefox, as I have it set to automatically update. OS is w10.

Also, I only have sync set for passwords. I don't have it set for tabs, for the reason that I use different ones on different devices.

Please, please, help!

Thanks in advance.

Just updated from version 140.0.4 to version 141.0 and all my bookmarks AND browsing history are gone! I do see the appropriate files in my Firefox profile folder.

I tried following the instructions in the "Fix "The bookmarks and history system will not be functional" error message" article (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US), but they are not correct, i.e., Solution 3: Update Security Software definitions does not apply as I have Defender turned off in favor of using ZoneAlarm. And those instructions say to update the definition, but there's not place to update the definitions.

I tried to import bookmarks from the Bookmarks folder, but when I click on "Choose file", Firefox either does nothing or shuts down without displaying any error.

100% disappointed with this update!

There seemed to be an update or change, but when I saw the tabs I had on my bookmarks they were from 10 years ago. It had links that no longer work, tabs on websites that I no longer used. I tried to use recovery but it just gives me info on 2 days ago. I don't know where to go to get my most recent list since I had all my payment links among other things. I don't know if it my toddler I caught her taping on the keyboard, I mention this because she flipped the screen on the monitor upside down. Please help I need to pay bills and I can't remember all the sites.

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

When I opened Firefox, all my profile settings were back to a Default. Lost all my settings. Looked up solution on Google, couldn't find an "Old Firefox Data Folder" anywhere.

Tried the other listed "profiles" in my profiles folder, none were my most recent profile with all my settings from the past months.

How can I find the profile that was used before my update which was done 7/27/25 ish.

Thanks, Jean [email removed]

Hello: I am trying my hardest to figure out how to move my existing Firefox profile folder (with bookmarks, passwords, etc.) to a new system. I have tried repeatedly to take the contents of the existing profile, and past them into the default profile on the new system. None of the information shows up.

The existing profile is version 115.25.0, running on a Windows 7 Pro platform.

The system I'm trying to move the profile to is a Windows 10 Pro 64 bit system. I installed the same version of Firefox on the target system.

All the files from the existing system seem to copy over to the new default profile folder fine, but no luck when Firefox is opened.

I also tried copying the entire profile folder over (leaving the folder name intact), and removing the default profile that was set up by Firefox. When I do that it just gives me a message saying it can't find the profile.

Don't know what else to do here. I have a lot of data in the old profile that I don't want to have to re-create.

-S

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?
