I-Firefox Community Forum

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

After problems with loading the current Firefox session, I seem to have retrieved my bookmarks (I cannot be certain all of them are there), except the Bookmarks toolbar and Other bookmarks folders are empty. I have a recent backup, but when I try to import the json file, it wipes out all bookmarks - I have to reboot to see them again. If I had them in html format I might try to manually add the missing bookmarks. Even better, maybe there is a way to merge the current and backed-up bookmarks. But I don't want to make things even worse. Any advice that certainly will work? Thank you for your help. Incidentally, sometimes the bookmarks won't load, and I have to reboot, sometimes several times, to see them again. How might I avoid this?

Hi! I reached out on Friday and was sent a code that expired in 5 minutes, missed the deadline and had to leave the library. I updated Firefox to 155 and can't find my bookmarks. Also found that a Microsoft update included Goggle Chrome that I uninstalled. Please advise on getting my bookmarks back thank you. I only have 30 minutes left on line. Thank you for all the work you volunteers are doing, greatly appreciated! Mark

Help! All of my bookmarks, browsing history, and profile prior to Sept 4, 2026 have been erased. Firefox instructions for restoring these prior bookmarks do not work. When I access "manage bookmarks" then the "Library", then "import & backup & restore", there is nothing listed prior to Sept 4, 2026. So there is no file to choose. Also my prior profile has been erased. My profile is completely blank altho I did NOT create a new profile nor did I access my profile in any way!!!

Also the instructions for "restore bookmarks from backup" do not work either. I desperately need that browsing history and those bookmarks. I am doing research for an art history project & those bookmarks for the last two years were stored there & seemed securely in place for the last three years. I need those bookmarks & the browsing history which included sites I used but did not necessarily cite in my research.

My bookmarks included the sole documentation I had of my research for this project for the last two years!!! When Firefox said it would continue to support Windows 10, I had no reason to believe my entire browsing history and/or my previously secure bookmarks would be erased. Help me restore those bookmarks. dona bretherick

Hi, I recently had to restart my computer and made sure that Firefox settings were 'open previous tabs on startup' before I shut down Firefox. I had about 30 tabs open, which were important and that I could not bookmark separately in time.

After the restart, I opened Firefox to be shown a screen that said 'Your Firefox has been updated'. None of the tabs showed up, so I closed and reopened Firefox, but am just shown a blank tab.

Please help, how can I restore my previous session with all the tabs?

I really need help with it.

Thanks

Somehow I got signed out of my account (no idea how). I've reset the password using the account recovery key. You sent a new recovery key but I seem to have lost that before I could save it.

Issue occurred on September 6:When I was running a game and updated my graphics card driver, Firefox was running in the background. My PC went completely black and became unresponsive, so I had to force‑restart the computer.

After rebooting, Firefox reverted to a brand‑new fresh‑install state. All my browser settings, login status, local profiles, browsing sessions, hundreds of open tabs and my categorized tab groups disappeared, only the welcome startup guide showed up.

I logged into my Mozilla account on my Android Firefox device. Some browsing history was synced back. However, synced history cannot restore the original tab session back‑forward page history, nor my manually sorted tab groups. All browser preferences, theme and language settings are also lost.

I originally had 4 separate local Firefox profiles on this Windows computer, isolated from each other for different work purposes. Only one profile was logged‑in to my Mozilla account and could partially sync data. The other three local profiles are completely gone. Those extra local profiles were NOT signed into any Mozilla account and were never synced to cloud storage.

In my Mozilla account’s connected devices list, there are two entries both belonging to this same computer: “MARSHAKK” and “Firefox by Administrator on MARSHAKK”, which correspond to my Firefox instance before and after the crash.

I cannot understand the community help articles about session recovery, and I’m unable to locate or restore my old local Firefox profiles and lost tab sessions by myself. Please give me assistance.

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,

There was an electrical outage and I lost all of my settings,pictures,bookmarks,documents,home page,every thing and I can't get it back....I have tried everything I know (which isn't much) to try and get it back,like a restore,downloading Firefox again thinking that would bring everything back,but nothing I did worked...I really need to get all of that information back up and running again as I have extremely important messages and emails I just can't afford to loose. How can I get my home page back, along with all my other settings? It is so important that I get all of it back !! Can an electrical outage erase everything off of a computer and if so is it lost for good or can I get it back? Please, Help!! Thank you :)
