Help! I had a ton of open tabs and bookmarks on my firefox, and it just updated itself without my permission and now everything is GONE. I can't click on Restore Session or find any bookmarks! I am very very sad.... can anyone help me recover these things?

I use firefox on Mac OS 10.14.6. Every time I quit firefox (Stopping the program, not simply closing all windows) everything is reset to defaults. For all intents and purposes, it's as though I deleted and re-installed firefox every time I quit out of it. Bookmarks are removed, and any default bookmarks I removed are re-instated. It also opens up the set-up and privacy web pages that it does for the first time when you open it. None of the preference files are locked, it's set to remember history and I'm not permanently in private browsing, it's not even supposed to delete cookies. It's been like this since the moment I installed it; refreshing firefox changes nothing, uninstalling and reinstalling it also changes nothing. The only thing that stays the same is that my computer keeps firefox as my default browser.

Firefox was one of the system updates I installed today on my Linux Mint 19.3. I updated it and discovered all history and bookmarks are gone. I have no Old Firefox Data folder. I tried about:profiles but the only other profile is the default Linux one. I tried to Restore from Import and Backup in Manage Bookmarks for several different dates, but only get "Unable to process the backup file" error. I also tried to choose several .json files from the STG-backups-FF-8x folders in Linux Downloads directory, but it doesn't seem to do anything. I've tried using Timeshift to restore from previous system dates, but it would only create Firefox folders with the same outcomes as above. I don't really care about history, but I have a lot of bookmarks that would be very difficult to recreate.

Thanks, in advance, for any help getting my bookmarks back!

All my Bookmarks and Tabs have vanished after the Firefox 82.0.3 update yesterday. Related? Searching for hours, including Firefox site and cannot find solution. I noticed 'Restore Previous Session' was recommended as a 'fix' at some links. Mine is grayed out...if that matters. I have VERY important bookmarks, including links related to Hurricane Sally destruction to my home. PLEASE HELP! I'm not very computer savvy, so 'instructions for dummies' would be helpful. PS...I was able to bookmark this page, but at least 100 bookmarks vanished. Tabs & Bookmarks are fine with Safari and Chrome. Unfortunately, I rarely used those and did not migrate most Bookmarks to them. Lesson learned. Thanks in advance John

I needed to have Windows 10 wiped and reinstalled from my laptop, and the guy who did it cloned my files to save everything. I saw instructions on another post on how to find the bookmarks file under Profile, but it didn't do anything after confirming that it would wipe out all current bookmarks. What am I doing wrong?

Hi. i ma having trouble restoring my bookmarks. firefox crashed and has deleted all my bookmarks. when i try to restore from a json file i get the error message cannot process the file. i have tried the json file restorer but it doesnt help.

This new 'update' has just caused me to lose all my tabs and bookmarks. The new version is c**p and it is awful. I went to the page to install the previous version I liked and worked perfectly and when I installed I now have none of my tabs and bookmarks. My pc is nearly unusable and I am now out of business until I can get them back if I can. It will be months to try to get back to where I was and will never get all of what I had. Is there any way to fix this? I need help immediately.

I'm getting Profile Missing: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I don't have a caches folder I can remove the contents of the application support folder and nothing changes.

When I go to open the profile manager I get:

MyName$ /Applications/Firefox.app/Contents/MacOS/firefox-bin -P Error: Access was denied while trying to open files in your profile directory.

1. 1. 1. !!! [Parent][RunMessage] Error: Channel closing: too late to send/recv, messages will be lost

I tried running Disk Utility but it froze the machine as it's a time machine disk and that slows it down immeasurably.

What's my next option?

I store passwords on firefox account and use sync to share passwords across devices. I did not delete any passwords on any device. recently, I saw that only google account passwords are missing and rest passwords are intact in saved passwords. my google passwords have been stored since a long time. all my old and recent stored passwords are shown in firefox but only my google account passwords are gone on all the devices. I tried login-backup.json but there is no change in passwords shown. need help.

My laptop died - but have FULL back up on ACRONIS cloud ... I want to find & restore my Firefox BOOKMARKS/ favorites etc. FIREFOX creates a PROFILE that contains all the data... BUT its hard to find!!??

I know location is USERname>AppData> Roaming>Mozilla>Firefox> PROFILES

BUT ... on my NEW Laptop when I go down through C:Drive hierarchy I cant see "AppData" If I search I can find ... BUT I cant actually locate via USER NAME.... Is this to do with HIDDEN FILES???

So when I go to my CLOUD BACKup I have the same problem. I can search & see ...but cant find in the hierarchy so I can recover those files & re-install on my new laptop... Any ideas where these hidden files are located?

Any ideas?

Thx for any help Cheers Keith

Hello,

For 1 week, perhaps since August 17, 2021, all of my usernames, passwords and main password have frequently disappeared.

This morning I closed the browser and launched it again. I have, a priori, lost nothing.

I restarted the computer. Again, the usernames, passwords and master password were gone.

I didn't changed any settings before or after the last update.

Any solution ?

Regards.

Opening FF today had error message about bookmarks and something (sorry cant remenber exact details) but had to shut down & restart which I did and now, whilst bookmarks are OK all my logins & passwords have gone. Opening the logins.json file shows nothing - it's empty. Checking the about:profiles shows the current one plus 2 others. One has logins but is from 2018 so most are wrong, (most of my currect logins have the firefox generated passwords) the other has none. Can I get them back?

How do I contact Mozilla Firefox to ask if I'm able to access to my Firefox profile on their cloud server?

Windows 10 would not update so I contacted Microsoft Support and a technician spent two days trying to various methods to get the updates installed on my computer. After several failed attempts it was determined a Windows "reset" was needed. The reset stated it would uninstall apps but save user data. However, it appears the reset uninstalled and wiped my profile off the computer.

I've already asked a previous question using the Mozilla Firefox support section and verified the profile is in fact gone. No backups are available to rollback using Firefox and the backup profiles in the "Windows.old" and "Windows.old(1)" both contain saved profiles from after the reset.

It sounds like my last option is contacting Mozilla directly to verify my account information and see if they can access my profile on their cloud server?

So how does someone do that? Thanks

Firefox continiues to wipe all of my saved password and bookmarks. After fresh windows install, I signed into my account and figured out that all of my bookmarks are gone. It happend for the second time. I have a mobile device running firefox which is lincked to my account. It's also gone there. How can I fix it or restore my data?

I recently got all new devices and traded in my previous ones and when trying to login to Firefox Sync, I can sign in successfully but then I’m required to provide the 6-digit code that is sent to my email. I am unable to login to my email because the password in stored in my Firefox Sync saved passwords.

Attempted to reset my email password (Gmail) but I need to enter the last password that I used, which I have no idea since I’ve always used Firefox Sync and all I get from Google is “we are unable to verify this account belongs to you”. So not much traction on gaining access to my email account.

In my mind, I assumed that by utilizing Firefox Sync as a form of a password manager, I wouldn’t be in this situation as long as I knew my Firefox Sync password. I have since learned otherwise. I can sign-in on accounts.firefox.com but of course making any change requires that I put in the code that was sent via email.

I attempted to download Lockwise and again prompted to enter the code sent via email.

So at this point, I’m just wondering if I’m out of luck and although I know my password to my Firefox account that I’ll be unable to regain access to it or my email because I can’t access the 6-digit code being sent to that email.

Any additional support or suggestions are appreciated but I feel like I’m unfortunately at the end of the line here on what else could be done.

Happened once a while back but happened again today. Firefox Sync asked me to reconnect, which I did. After that reconnection, and even if "password" is checked in the parameters, all my passwords have disappeared. I do also have Firefox on my phone, which have all my passwords from before the first instance it occured, but it never synchronized to Firefox on my computer. No error messages appears when synchronizing, and everything seems to be normal. Any way to correct the non-synchronization of passwords ? Is there something I'm doing wrong ? Thanks.
