Suddenly! Cannot open Firefox because of the error message: "Firefox profile missing or unavailable."

I found the profile in my Library.

Looked for internet advertised "Firefox profile manager," but could not find it. Only one I could find was obsolete.

Thank you.

Hello,

since yesterday after closing FF to restart, I encountered a problem. Everytime, when I try to open FF, it says that the profile isn´t available or not accessible.

I tried already to rename in /library/Application Support/Firefox, Profiles.ini -> Profiles.iniOLD and the folder Profiles -> ProfilesOLD.

As well I tried to call the Profile Manager from terminal using the below commands, since FF isn´t open. /Applications/Firefox.app/Contents/MacOS/firefox-bin -P /Applications/Firefox.app/Contents/MacOS/firefox -ProfileManager

No matter, whether I rename the profile.ini or try to call the profile manager. Each time I get the same warning, that the profile isn´t available.

Since I tried every possible solution, which I could find on the help pages, I hope to find help from the community.

best regards Corey

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

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!

I lost my Firefox profile data (amongst other files) after a hardware issue forced a repair and a factory reset. I purchased the EaseUS Data Recovery tool to try recover my Firefox data but am running into issues.

I located the two folders (one ending in ".default-release" and the other ending in ".default-release-1632317792925") from the PRE-reset file location C:\Users\[User]\AppData\Roaming\Mozilla\Firefox\Profiles.

I then close Firefox, delete all of the folders from the same location in the POST-reset location of those same files, and paste the older folders in their place.

However, when I start Firefox, it only shows me POST-reset tabs. Am I doing something wrong?
