Firefox cannot read or write to profile

I'm on OSX 10.6.6 and recently used a recent Time Machine backup to restore my system on a new 1TB western digital drive. After doing so I cannot start Firefox (3.6 or 4 beta). After clicking on Firefox.app I get "Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible."

The following message is printed to the console: [0x0-0x31031].org.mozilla.firefox[493]: Error: Access was denied while trying to open files in your profile directory. com.apple.launchd.peruser.501[275] ([0x0-0x31031].org.mozilla.firefox[493]): Exited with exit code: 1

I tried to delete my old profile from ~/Library/Application Support/Firefox and the problem persists. Running /Applications/Firefox.app/Contents/MacOS/firefox-bin -ProfileManager results in the same error.

The file permissions on the ~/Library/Application Support/Firefox directory are:

drwxrwxr-x 2 my_name staff 68B Feb 20 08:31 Firefox

I'm at a loss here because the permissions look correct. When I run the ProfileManager as "sudo" it starts correctly and let's me edit/create a profile for "root".

Any help regarding getting the correct permissions would be very helpful.

Did you remove the file profiles.ini as well?

I believe it's concerned with the profile directory rights. On Linux, I've cracked the problem like this: chmod ugo+rwx [dir.name]

Thanks for the replies. The profiles.ini file was removed too. I tried changing the permissions like:

chmod ugo+rwx Firefox chmod ugo+rwx Firefox/Profiles

But the problem persists. I did a full check of the actual disk using Onyx and everything checked out. I can't imagine what the problem with that directory could be.

I'm not familiar with Mac. On Linux, it's possible to change an application's start parameters by editing shortcut. One can change Terminal string from false to true. Thereafter a console report would follow.

Try to move the Firefox folder in /Library/Application Support/ to the trash to make Firefox create a new file structure for the profile.

I'm experiencing exactly the same problem on Mac OSX 10.6.6 after a Time Machine restore. I have attempted the following:

1) uninstall and reinstall FF 3.6.15 2) manually remove profile folder 3) install FF3.6.15 4) install FF 4rc over 3.6.15 5) reinstall java: Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode) 6) executed sudo /Applications/Firefox.app/Contents/MacOS/firefox-bin -ProfileManager

Using sudo, Profile Manager will launch from the terminal, and allow me to create a new profile. However, if I quit FF and try to launch it from the dock, I get the same "Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible." error again.

I can't determine whether there's a connection or not, but I've also suddenly lost the ability to attend GoToMeeting sessions, and those used to work fine as well.

It may be related because I realized I can't attend gotomeeting sessions either. I also can't use any MS Office features that need the MS Office Database. Must be a time machine restore issue of some kind. Strange that disk utility doesn't spot any errors though.

How do you "run" a command? And where is my "home directory"?

I know how to open Terminal, but past that I have no idea. Do I copy and paste, hit enter? No clue...

Sounds like you are on a mac jayriggs. Just copy and paste the following command in to terminal:


sudo chown -R `id -un`:`id -gn` ~

and then hit enter. your mac will then update the permissions on all of the appropriate files in that directory. Depending on how many files you have, it might take a couple of seconds.
