The launch of Firefox Profiles seems to have obliterated everything in my account: bookmarks, history, open tabs, and extensions are all gone completely. I have an option to import files from another browser, but not from my own past firefox. I logged into my Mozilla account, but I didn't have any other devices so I think it was still unable to recover the data? Is there anything I can do about this, or is all of my data truly gone?

Had a crash earlier on my macbook that required a restart. Everything else is fine but I have lost all history and bookmark data on my firefox browser. I tried going to see if i had the wrong profile and that was not the issue. I tired recovering the bookmarks in the manage boomarks option but there were no backup files.

I have some important bookmarks i need recovered. Any help would be highly appreciated.

bookmark bar and all my bookmarks are gone I followed Support instructions, clicked on Manage bookmarks and went nowhere. I really need this function to work as I am sight impaired and can't use my phone for much. Please help.

EVERY TIME I CLOSE FF WHEN I REPOPEN IT, I END UP BACK AS IF I JUST INSTALLED IT. ALL MY BOOKMARKS ARE GONE, ALL MY EXTENSIONS ARE GONE, LIKE I JUST INSTALLED IT.

I'VE TRIED UNINSTALLING AND REINSTALLING AND IT STILL DOES IT.

My laptop crashed and I had to format my hard and install new windows.

I have kept my passwords database files, which uses to be key3.db and key4.db along with logins.json and logins-backup.json files from my old use with me separately...

But the new Firefox folder didn't create these files anywhere where I could replace them with my files to get my stored passwords back.

Please help me restore my data from these files onto my new Firefox so I can get my stored passwords back.

Не знаю по какой причине, возможно какой-то баг или ещё чего, но у меня пропали все вкладки, даже те, которые были сгруппированы. Возможности восстановления предыдущего сеанса у меня нет.

The initial problem I was dealing with was FF kept directing me to Youtube every time I clicked on a NORMAL link in my google search. 🤷‍♀️ I tried several different links but same result....Youtube again!

This is where I went down the rabbit hole. 🙄 My first step was to get some help with my Firefox browser for this 'redirecting' issue. Under the help heading, "More Troubleshooting Information" I found "Give Firefox a Tune-Up using Refresh". Hmmm, maybe this will fix the issue?? I carefully read the following before proceeding....

"Start fresh to fix performance issues. This will remove your extensions and customizations. You WON'T LOSE ESSENTIAL INFORMATION LIKE BOOKMARKS AND PASSWORDS."

WRONG!!! MISLEADING!!! LIES LIES LIES!!! 😡😤😡

I lost almost ALL of my saved bookmarks except for TEN (the most recently used) that still remained after the refresh was completed! I literally lost over a hundred of them that I had accumulated while using Firefox for so many years!! 😲😣🤦‍♀️ 21 different folders, Home, Travel, Shopping, Banking etc, each containing 10-30 OR MORE bookmarks to sites I need to SAVE to be able to revisit later when needed. ALL GONE!!! 😡😤

I have been loyally using ONLY Firefox as my browser for 2 decades!! Now the only thing I can say about Firefox is a whole lot of curse words!!

WHY WOULD FIREFOX INCLUDE SUCH A #$@&! STATEMENT??? "You won't lose essential information like Bookmarks and Passwords"......YES YOU WILL!!!

This NEEDS TO BE REMOVED!!

Why not be an honest and reliable browser?? Include information that if you perform a refresh, you WILL lose these essentials but you might possibly be able to recover them from hidden files somewhere, but you won't easily know where to find them!! 😉

The next time I have ANY issues using Firefox I won't be 'refreshing' nothing at all!! I won't troubleshoot NOTHING!! I will just copy and save all of my bookmarks and SWITCH TO GOOGLE CHROME!! 👍

I got a new PC and tried to sign in to my FireFox account to synchronize. But, foolishly, I ended up resetting my password! Don't know why did that, as I was able to locate my password stored elsewhere. I think this action erased all my data in my online profile & I cannot access my account data (bookmarks, user IDs & passwords) online.

Since my data was still in my old PC, I followed the directions for finding my Profile folder. I copied the folder contents to the Profile folder in the new PC. This has not worked.

I realize I wasn't supposed to copy the entire folder contents, which could be the reason why it's not working. Also, the profile folder contained a large amount of data (3 G). So, it's possible that not all files have been transferred correctly.

Please help me!

Thank you very much! Madoka

w11 on laptop. Cleaned PC using CCleaner. Restarted windows. Launched Firefox and only 1 tab with calendar opened. Went to History but no indication of the previous session available. ?

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

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.?

I'm not sure whether i am in the correct forum. I have successfully copied to a USB stick the bookmarks from my old PC but, although I can open the html file and see them, I cannot see how to present them in the bookmarks menu. I am not recognising a simple "import" option such as I found with passwords. What am I missing

So I asked a question yesterday with the same problem but since then I've done a lot of my own research & what-not so I'm hoping I'm little more educated on what to do, however I'm just not fully understanding what I'm doing wrong, unfortunately.

So a run down of what happened yesterday. I was told by a microsoft guy to do a factory reset but select the option to keep my files. Which I did. I thought because I have a Firefox account my passwords will be uneffected. I did the reset & came back, downloaded firefox for their website, went to sign in & of course, I forgot my password for that, I hit forgot password & I was told to insert a 32 key code. I was never once given a code, I've had my account for yeeeears. I had to forgo entering the code & yup, everything has been wiped.

Since then in my research, I've heard many people talking about C:/Windows.old/users/kelsi/AppData/roaming/mozilla/firefox/profiles - I have this in my folders. Inside that there's also logins & logins-backup (JSON files) & key4 file. When I open up the logins into my notepad app, I see all my sites that I have passwords for (encrypted) so they are there! I then also have C:/Users/kelsi/AppData/roaming/mozilla/firefox/profiles/profiles (there's two folders labelled profiles). I was speaking to a few users online who said that I've to copy & paste the C:/Windows.old(...)profiles onto the C:/Users (...)/profiles & then start up firefox again. I did all that, opened up firefox again but nothing. However in the c:/users folder upto & into the profiles folder, it's got the key4, logins, logins-backup there. When I open the logins file on notepad, all my encrypted passwords are now also in the c:/users(...) profiles section.

So I'm just wondering what to do now. I feel like I've gone crazy trying to figure this out. I've got a lot of resources to use, spoke to so many people but I seem to have hit a deadend. I'm a complete beginner with all of this, I only use my laptop for Firefox, so I really don't know much about the ins & outs of anything else. I am hoping this makes sense to someone & can point me in the right direction of either where to go next or what I've done wrong (I can't emphasis enough how much of a beginner I am, so please make it easy to understand) Thank you in advance.

Something very bad happened to me today (11/3)....

Firefox 144.0.2 was installed on 10/30/25, and everything has been fine until today. I don't know why or how, but ALL of my OPEN tabs (of which I have many--and have it fixed so they always re-open when Firefox starts), ALL went away.

In reading conventional steps to recover such from sessionstore-backups, those instructions sounded straightforward. However, even though ALL FIREFOX PROCESSES were ended, I could not copy the contents of the sessionstore-backups folder nor could I delete anything--EVEN THOUGH I am the owner.

Even after providing Admin perms.

I could get rid of profiles.ini, which initially proved diasterous, because then Firefox thought I was brand new, so ALL of my passwords saved through Firefox these many years, went "poof".

Fortunately, I was able to get that back, but I still cannot get all of my tabs back, and conventional instructions to do so aren't working.

After recovering from my heart attack for initially losing my passwords, I am breathing a little better right now, but it sure would be nice to get all of my open tabs back again. I don't know why I am not able to manipulate the files within sessionstore-backups. I think if I could eliminate the files in that folder EXCEPT for upgrade.jsonlz4-20251027123126, which possesses a 10/29/25 date, these should be the open tabs just before the 144.0.2 installation, and all should be right with the world, once more.

I have performed/examined many steps offered under this category, but most assume I can copy them elsewhere for safe-keeping and/or removing all but the one I want Firefox to "use". Because something is preventing me from doing this, though, I am being stymied in what ought to be the solution. As a test, I was able to copy files from a much older profile--so I can prove the basic steps SHOULD HAVE worked. Unfortunately, I cannot do the same with THE (more recent) folder in question. I can't get rid of parent.lock, either (and I have ensured no Firefox processes are running via Task Manager).

Repeatedly.

Something else is at work, here. Any help or assistance from community experts would be most helpful.

Thanks very much in advance.

I was trying to Sort by Name, but hit Delete, because the right-click menu presentation shifted. No worries, Ctrl Z should undo on PC. Nope. Now I'm learning the only restore is through JSTOR/backup. I don't want to restore a previous state of operation. I want to un-Delete a folder. Is that a feature somewhere, somehow?

And secondly, can I force confirmation for all future folder deletions?

There are times that when I open firefox that some of my tabs that does this weird thing where my tabs from the previous session that I left doesn't load up, from what I see is a blank tab that doesn't access the sites I left. It's been twice since I encountered this and I can't replicate the issue. When it happens I try checking out the recently closed tabs or window it doesn't show the ones that didn't show up.
