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The articles on restoring from backup are outdated.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!

Dell desktop running Mint Mate 22. Bookmarks missing about 50% of bootups. Saved bookmarks to both HTML and JSON during an occasion they did appear, when they next were missing attempted to restore them via Library pop-up (Manage bookmarks). I could not determine a path to direct the system to either locally saved file. In Library, selected Restore, which then asks me to choose file, but none of the data fields accepted or acted upon input. re-installed Firefox but same result. Then clicked on the saved HTML file, multiple screens flashed on the display, with multiple items in the tray. The final result was the bookmarks were all displayed as expected, but since the problem has been inconsistent, unknown whether they will display on future bootups.

Wish to have guidance on using the Library pop-up to restore saved bookmarks when they are missing. Perhaps some knowledgeable user could post a step-by-step through the restore process.

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

ello. My favorites have disappeared from my Windows 11 PC. It has happened once before and then I was able to get them back by deleting the sqlite file, now it doesn't work and I need your help with ending firefox processes etc.

Ok, I screwed up.

I was trying to solve a problem I've been having with regular releases of Firefox and it occurred to me try the ESR release so I downloaded and installed it. The good news is that it solved my problem, the bad news is that I just barrelled into it without thinking, assuming that my logins and bookmarks would just transfer over like with regular releases. They did not. It turns out I should have made a backup of those things first and I can't open the old regular release of Firefox to properly back-up those things now. Oops.

I've been reading lots of forum posts here and elsewhere trying to get those files into ESR and I haven't been successful. From the profile manager I've located the profile that still contains that info and I've tried:

Copying and pasting the "logins.json" and "key4.db" files from the "default-release" profile into the ESR profile which didn't work.

From "about:profiles" I also tried to "launch profile in a new browser" of the default-release profile so I can open that profile and properly back-up bookmarks and logins but I get a prompt to create a new profile which I tried several times and only resulted in several profiles of the ESR release.

Then it occurred to me that If I could just delete all instances of ESR and open the old default-profile then I could back-up the logins and bookmarks, THEN download and install ESR again and import those files but before diving into that I need to make sure that won't loose my original default-release profile info.

So experts, does that sound reasonable? Delete all instances of ESR so I can open the regular Firefox? What's the best way of going about that?

Thank you.

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.

1785894397652 SessionStore ERROR NotReadableError when reading session file: recovery: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.jsonlz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available 1785894397756 SessionStore ERROR NotReadableError when reading session file: recoveryBackup: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.baklz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available

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.

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

I am at a complete loss on this. A recent firefox update has shifted all my site logins and passwords elsewhere in mystery and impossible to recover nor find them. I tried "Restore bookmarks, passwords and data from an old Firefox profile" but the profile is simply not there and the instructions completely haywire. I have nothing on the profile page. What have you lot done to make this completely unusable for the small person ? I thought I was computer savvy but now firefox is making things unnecessarily invisible and over-complex.

Installed to new system because old system was updated to Win11 and it failed. Old system is only partially operable. Trying to copy (export and import html files) of the bookmarks to the new system, but even though the import seems to have worked, I cannot get the program to show the bookmarks correctly (or at all). They appear in the Manage Bookmarks window but will not appear on the desktop view. What am I doing wrong? When I import them, I select the All Bookmarks item to copy to but it copies everything to the Bookmarks Menu folder.

So I just upgraded my pc and it bricked my windows and to reinstall, I forgot to save the Firefox data before doing so because I thought it wouldn't cause any issue, well, now all my bookmarks etc. are gone and I'm wondering if there is some sort of backup somewhere saved by Mozilla in the cloud.

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

Hello,

My Firefox app was crashing, so I turned off my computer. When I turned it on, Firefox was completely reset: no profile, app initialization... I also cannot find my profile into my files.

Could you help me please ?

Lost all tabs during an update including(weirdly) all theme stuff. Its not in the restore in history. But the themes part is the one that is strange, because why would themes change during an update, all while all my tabs are lost?

You forced an update and all my open tabs vanished into thin air. I was working with those!!!

I tried to follow the history recover path, no-go. I tried the json file path and can't get Firefox to open the tabs in the json recovery file from a month ago, not that that would be helpful anyway since I want yesterday's before the update!

Now I gotta spend a lot of time finding those scientific papers again - should charge you my hourly rate for wasting my time.

It's sh.it programming that's what it is. Bet you they were using AI to do the update.

Well never mind, I've grown tired of Firefox anyway since it just starts using 80% of my RAM when I have more than 10 tabs open. There's other browsers.

Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.
