Hi!

I appreciate all the work put into developing 155, and I can't keep up. I'd like to get my book marks back. How can I return to an earlier version, unless you know a way I can get them in 155, Thank you! BTW I'm using Windows 10.

Hello I've made backup file today before uninstaling my OS. Now I want to restore data afrer reinstalling my OS, but I keep getting error. Error added. Please help me to restore my data!

Alors que je n’ai pas demandé de mise à jour une nouvelle page Firefox est apparu sur mon ordinateur, iMac Apple et tous les marque-pages personnelles et autres ont disparu, Que faire pour opérer la totalité de mon ancienne version dans ce nouveau navigateur,

After a update 154.0.1 and 155.0.1, 64 byt Firefox dod not keep the open tabs once started, but the bookmarks. After searching in Firefox help, neither I could not find a previous bakup folder, before the update data, so I cannot restore the history it manually, so I do not know what to do. It is quite dissapointing as I had dozens of tabs open for diferent putposes, and now I have no one

i have made sure that all the settings do not force signing out, all settings include save passwords/bookmarks etc.

But... when I close firefox Im forced to sign in when I reopen the browser, it also looses all my bookmarks and passwords and I have to re-import them from the firefox backup.

I have deleted various temp files and force firefox to create new ones.

Can't get around this. It becoming such a farce that I'll abandon firefox and go to Opera!!!

I accidentally deleted my old Firefox beta And I need to recover my settings bookmarks and data etc by logging in how do I do that immediately? I'm trying to recover my old Firefox beta account how can I do that immediately

I installed and update this morning, September 7, 2026, but now all my previously saved bookmarks (prior to September 7, 2026) are not accessible or shown. How do I recover all of them?

I made a change somewhere that caused a total loss of history/open tabs even in my tab manager extension. I can't remember exactly what it was I changed but nothing I have searched here has been helpful in recovering from this. I did not want to bring my profile from home as I am using Firefox here in a work environment. Can someone point me to or explain a step by step method to be able to do this? Nothing I found in searching here has been positive.

I recently made a backup (via the option under Account and sync in the settings), as I was switching to a new OS. Unfortunately, when selecting the backup in the new OS, I am greeted with the error message:

This file isn’t working. Try picking a different file.

According to this, my file is corrupted. Is there anything I can do to fix this, or have I just lost all my data? I no longer have access to the profile files in the original OS.

I am trying to restore my firefox bookmarks and passwords from a back up I saved. I am signed into firefox in my browser, I go to restore back up and firefox restars and my bookmarks appearm but I'm signed out of firefox. When I sign back in, my profiles and bookmarks disappear?

My PC crashed and then upon opening up firefox it forced me to update firefox. Afterwards all windows and tabs disappeared but my browing history is still there. I tried the in-browser restoration but it is greyed out. I tried the session store backup profile data but has no 'previous' or 'back up' files, only 'restore' files that are empty and restore to no tabs or windows. What other ways are possible? It's weird my browsing history anf bookmarks weren't deleted at the same time.

Hi, I've accidentally created a new profile and I totally didn't know what was happening as I've had this internet browser setup for years and didn't even remember creating a profile. That's why I ended up deleting all profiles thinking that's how to get things back to how they were but now everything is gone, years worth of saved bookmarks, passwords etc. It only happened recently and I have not restarted my laptop, not emptied the bin folder etc. Is there any way to recover my profile? I'm on a Mac.

Hello,

I recently opened Firefox and noticed that all my data (bookmarks, saved passwords, and history) is completely gone. I didn't make any changes or delete anything myself.

Could you please help me understand what happened and how I can recover my lost data?

Thank you.

Hello, Since this morning after an update of firefox the history is lost and my personal bar where I stored my bookmarks is empty now after applying version 155.0.1 the problem is still alive Help Please
