I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

Attempted to update FF using the 140.2.0esr.msi file. During install it asked for a location of bookmarks (seemed off, like a new install) so the process was stopped. All FF profile files appeared to have been untouched based on their dates. So the following directories: \AppData\Local\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr \AppData\Roaming\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr where both copied to a secondary directory as a safety precaution. Install was restarted and it appears to have again installed a new version with no bookmarks, extensions or password DB carried forward from the previous install, which is not what I wanted.

Can this be corrected, by moving the copied profile back in.

Thanks, Brian

What seems like ages ago Firefox stopped displaying bookmarks I addition it would not add new bookmarks nor restore the existing ones. I've gone through all of the corrective procedures listed on and off but nothing works. As a final attempt I deleted the program and reinstalled it. No change. It seems to me that perhaps a missing file from another program or system is missing. Maybe!

I have been using an alternate system for some time. When installed it had no problem finding all of the Firefox bookmarks and placed them on the menu bar as "Firefox Bookmarks". I have no issues with using them but all new ones are stored in the current browser. Thus the new ones do not go into the folders previously set up. I've avoided moving them manually to the new system due to the volume but I am ready to bite the bullet.

I prefer Firefox but it's just not working.

Can anyone save Firefox for me.

Ich habe die Passwortliste bei Einstellungen aufgerufen und die war leer und alle gespeicherten Passwörter waren weg. Ich habe sie aber nicht gelöscht. Wie kann ich die Liste mit den Passwörtern wieder wieder herstellen ?

I updated Firefox last week. A few days after, I discovered that when I signed into Firefox, I couldn't find my bookmarks or extensions that I'd had on it before. I tried the "Import bookmarks" menu, but it only gave me option to import from Microsoft.

Then, I saw two firefox icons on startup menu. When I hit a faded-out one, I got into Firefox and did see my old bookmarks and extensions. When I clicked a fully colored icon, I got into Firefox but couldn't see my old bookmarks and extensions.

I saw firefox listed twice on my "uninstall" menu. I uninstalled the later one. Now, there's only the fully colored firefox icon on my startup menu, but when I click it, I still don't see my old bookmarks or extensions.

Trying to log in to my account a few minutes ago to get help, I was told the password I was using didn't work, so I came up with a new one. When I logged in after that, I got a message saying my old data might not be available.

Is there any way i can get my old bookmarks and extensions back?

I have been using the same firefox account for six years, and when the update that added user profiles came out, I successfully transferred all of my information to a profile. Well, today my firefox wasn't responding, so I used task manager to close it and restarted my computer. When I opened firefox again, it prompted me to select or create a profile to continue browsing. Crucially, it did not list the profile I had been using as an option, so I created a throwaway profile so look up what was going on and how to fix it. I tried logging into my mozilla account; no record of my previous browsing data, bookmarks, or extensions. I tried following the steps in the "Restore bookmarks, passwords and data from an old Firefox profile" article from Mozilla Support, but my old profile no longer appears in the profiles folder on my computer. I'm worried that if I keep messing around trying to restore my old data, I'll do some irreparable damage and never be able to get it back. Is there anything I can do in this situation?

since Vers. 142 I am having a really bad and wasteful time searching for my previous tabs when firefox is closed....initially it worked, but now RESTORE PREVIOUS SESSION IS NOT ON THE MENU UNDER HISTORY.... WHY IS THIS ALWAYS A PROBLEM WITH UPDATES???? IT SEEMS THAT THE UPDATES WHEN LISTED DON'T SHOW HAVING ANY TAB INFO, BUT SURE AS DAY/NITE WHEN I TURN MY DESKTOP AND FIREFOX, TABS ARE MISSING AND I CAN'T RECOVER THEM.

IT WOULD SEEM THAT IF THE DESIGNERS REALLY WANTED TO DO SOMETHING WELL, THEY SHOULD BE TRYING TO FIND OUT WHY THIS HAPPENS ON A REGULAR BASIS.

CAN'T "SNIP" A PICTURE OF MENU, SO HOW WOULD I MAKE A COPY OF IT SO YOU CAN SEE THAT RESTORE PREV. SESS. IS MISSING?

I have a machine I've been using for months and haven't got around to archiving the history and tabs for some research I was doing. I realized this could be problematic if anything happened to the machine, so I decided to sign-in to my Mozilla/Firefox account I made years ago, so it would be safely sync'd.

Everything was fine at first, it showed it was syncing and whatnot, but then after several minutes, Firefox crashed. Upon relaunching, ALL of my history is gone! Neither signed-in nor signed-out shows any history at all, except the searches I've done just now trying to undo this mess. Did I really just loose months of history due to some bug or is there a way I can manually restore or see it from the mess of cache/profile files on my machine?

Ubuntu user, so will be at ~/ or similar for most things I assume.

I have installed Windows 11 to replace Windows 10 but my bookmarks in Firefox have disappeared, is there a way to retrieve my bookmarks that always appeared each time I opened Firefox?

Hello, on the 24th, I had opened a new tab to search something, like normal. It wasn't loading, so I closed my window of 20 or so tabs to reload the browser. When I reopened the browser, none of my tabs were there, and the "recently closed windows" option wasn't available in the three lines menu in the top-right of the browser page. I cannot search for all of these tabs individually in my history, as some of them were saved from many months ago. But I needed these tabs open to refer to them for work.

I saw a page describing how I could reload my last session from C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\khv448gm.default-release\sessionstore-backups, but those files had already overwritten with the session that didn't have any tabs. I looked through the "Previous Versions" tab in properties, but it only had previous versions of the folder from earlier that day, and not before I had closed the browser. I asked my IT department at work if they were able to load a previous version of the folder for me from before the 23rd, but they just redirected me to Mozilla support first.

My question is, is there any way I can restore all my old browser tabs? Or is there anywhere else I can look on my computer for locally stored previous sessions from before February 24th?

Thank you!

FF 148.0 was running on MacOS with my profile as a folder (e.g, trb618r9.default) under Firefox. When I looked in history it was empty so I restarted FF, none of my tabs were there, and TreeStyleTabs didn't display. Investigating I see a new folder named Profiles that has a profile in it with the trb618r9.default name but not all the data in the original trb618r9.default. I renamed the "new trb618r9.default" and moved the original trb618r9.default to Profiles and restarted FF but still am not seeing the original fxxx data which still exists.

Screenshot of finder before I renamed etc. as described above shows the two same named profiles.

How can I recover?

Hello, I have been having some problems with my computer and ended up with 2 Firefox versions. They are both exactly the same 115.33Oesr. In the trouble shooting information it looks like they are exactly the same. The main difference is that the older version has all my Saved Password Logins. The newer version does not.

Another interesting thing is that only the newer version is in my Programs an Features. It says it was downloaded today. I downloaded a few days ago. I did do a System Restore to take care of another problem.

I was hoping to uninstall one of them but only the newer version is the one showing in my Programs. I am afraid to uninstall it and end up not having a Firefox at all or to loose all of my Saved Password Logins from the older version that is not showing in my Programs. I have a lot and I use them constantly. Just easy to sign in. Too many different passwords, impossible to remember. I do have a book with all of them but it takes forever to find them. How can I merge all these Saved Passwords Logins to the newer version?

I would really appreciate all the help I can get, please!!!!

I have used the OneTab browser extension for years. Mac computer ran out of space but was completely backed up. Got new computer. copied Firefox profile from the and updated the profiles.ini to use the backup data.

I used a backup dated 12 Feb 2026.

I was able to restore my bookmarks and passwords from this profile, but they seem to be from many years ago. I was not syncing to my Firefox account and saving the passwords to my computer. i assumed they would be in a bakup. None of my OneTab items were restored.

I wonder if part of the problem is that Firefox wants to ( and did) update my new computer to Firefox 145 or 147. I don't know which Firefox was running when I had the issue but I suspect it was older.

All of the storage/moz-extension files are there and firefox is using the correct profile data. Is there any way to find/read/extract the OneTab history? Where should I look? I contacted OneTab and all they could tell me was to look in storage/default/moz-extension.. ( nothing readable there) Thanks
