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The articles on restoring from backup are outdated.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!

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

last time my firefox crashed when i was using it and when i reopened my browser all of my history were deleted and they keep telling me that some sort of file is not able to save the bookmarks and history

Help! My bookmarks tool bar is missing & I cant recover it because your instructions for locating the menu bar don't match what your instructions display. There is NO AltGr displays a bookmark menu BUT I CANT MOVE IT TO MY TOOL BAR. There is NO selected tab, NO menu bar; NO bookmark tool displayed. I have also lost all of my downloads. This has happened in the last month; everything was fine. I am 82 years old & NOT a techie so expect better help than I have received so far during the last frustrating 2 hours of trying to follow Firefox instructions that DO NOT APPLY TO ME. Also the "add images" function @ bottom of this page won't let me send you a copy of the instructions you display to select the bookmark menu bar ... I click on the picture of the problem & nothing happens ... just dead no access to select pictures either.

I have NOT changed my internet provider; I have not changed any settings. This all happened two weeks ago. Called internet provider & they said it was Firefox issue!!! Very unhappy.

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

Why cant I access "ask a question" anymore as no link appears. How do I contact someone as the community has locked the thread concerning lost bookmarks. I need those bookmarks back!

I started a new conversation because all of my bookmarks have disappeared. I have five years of important bookmarks which I assumed would be kept in bookmarks. Now only the one bookmark I made today is available. Also Alt and AltGr does not link to anything. This happened in the last month. Also the "add images" link on this link is not functional anymore; I cannot select a picture either. I have Windows 10 and my system lacks the capability to upgrade to Windows 11 even if want to. Firefox says it will continue to support Windows 10 but something must have changed in the last several weeks. dona bretherick

I use Firefox under Fedora (I'm two OS versions behind, must upgrade soon). I open very many tabs each day then work through them, theoretically every day, in practice they accumulate and I deal with them when I can. I rely on the tabs loading correctly on restart, but today they didn't, instead the set of tabs that were opened a few days ago loaded, and I lost everything I had done since then. Is there a way to retrieve the tabs that were opened just before this happened, ie around 15-20 hours ago? Ideally, again, I would merge them with the current ones, but reopening the old ones would take much much longer than reopening the new ones. Thank you for any advice.

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 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.
