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?

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

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

I haven't been able to use my bookmarks now for a few weeks and you keep updating but nothing gets resolve. Years ago MOZILLA was great with not issues but lately is always a problem and sometimes is even blocked. Was going on there?

1- Firefox shows I have windows 10. Not so. I have windows 11 home, version 25H2. This may be problem that causes the issues. 2- Since Update months ago, profiles, bookmarks and passwords disappear constantly only for me to replace manually the bookmarks and passwords to disappear over and over again. Don't need multiple profiles just one that works as in the good old days. Used it for years but cannot find help and ready to delete and just use microsoft edge. Totally out of patience. ?????????????????????????????????????????????????????????????????????

Every few days, when I start Firefox, my bookmarks load, but they are non-functional, and the logos to the left of each bookmark name are missing. I can restore previous days sessions, but I lose all of my saved log-ins to frequently visited sites. Why is this happening?

Running Windows 11. Firefox was running at the time the hard drive crashed. When installing FF on the new drive, found the last profile folder set to parent.lock. Since it's the entire folder, I can't see which of the files in the profile were locked. I have a backup of two weeks prior (separate issue -- I was unaware my nightly backups weren't working for two weeks), but I'd like to recover the bookmark and password changes in that time.

Is there a way to get into the folder, or do I just need to accept the loss and go with the previous backup?

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

Every time I go into firefox there seems to be another update to download. I conform to ensure I'm up to date. The latest has changed my display to a basic display. All my bookmarks are gone. I cannot access the back up file on my W11 computer. I have a new android phone and I installed firefox on that, but I have yet to use the application as a browser, on that phone. I tried to recover from the phone, but it does not give me the options to select to follow the steps firefox says I should take. It does not allow me to scan the QR code. I desperately need my bookmarks. If I go to the help, obviously others have the same problem. I see the questions but no answers, I am signed in. I have been trying now for 2 hours. Please help.

Why does Firefox do this? Its not the first time this has happened to me, but now I'm lost.

After several windows problems, I did a clean install with forgetting to sync or backup on my profile and lost a good bit of my bookmarks. However, I managed to retrieve some files, but they seem corrupted and after going through forums and several researches, I am unable to use them. I tried to look at the files and some of them turned to chinese and others have strange symbols in them. Thanks lovely people!
