Firefox does not respond when I click the Help menu and select Troubleshooting Information.

more options

I have a deeper problem with Firefox, which is that it doesn't respond at all when I type something in the address window and press return. Following some of the help pages, I am advised to try resetting Firefox by clicking on the help menu and selecting Troubleshooting Information, and then pressing Reset. However, nothing at all happens when I click on the help menu and select Troubleshooting Information. Also note that I tried restarting in "safe mode". I'm told that this can be done by selecting "Restart with add-ons disabled" also in the Help menu. However, this doesn't work either. I have to hold down "option" while starting Firefox. Does firefox not work with OSX 10.9?

Holding down the option key should work to get the Safe Mode / Reset dialog. However, if Firefox is still running, you will just get a new window. You might need to force quit the program

Holding down option key worked, but Safe Mode didn't do anything (didn't fix the problem) nor did Resetting. Firefox ignores everything I type in the address window. There is no way to use Firefox (it doesn't respond to anything other than bookmarks - which were imported from Safari).

No other suggestions? That's unfortunate, because I'd like to use firefox. Does it just not work on some systems? Any ideas what might be wrong?

Sorry, as a Windows user, I'm not handy with some Firefox issues on Mac.

Could you check cor-el's reply at the end of this thread and see whether that helps:

Did you try to open a new window to see if it works there?


Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

OK, when I create a new profile and start Firefox with it, it works perfectly... UNTIL I close Firefox and restart. What could be corrupting or causing the profile to stop working, simply by quitting Firefox and restarting??

It happens without fail every single time I restart Firefox.

Does it help if you start Firefox in Safe Mode by holding down the Shift/Options key?

more options

No, it doesn't help to start in safe mode. The only way to get it to work is by creating a new profile. However it only works once per newly created profile. The very next time I try to open Firefox - without fail - it opens but is completely unresponsive. Something is corrupting the profile every single time. Any ideas?

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that has effect.

I'm not using a windows machine. What would the mac OS X 10.9.2 equivalent be, do you happen to know?

more options

Does anyone know what might be causing the profile to work once, and only once? Quitting Firefox and restarting hoses the profile so that it isn't useable anymore. Creating a completely new profile every time is obviously not a viable option. I need to find out what could be corrupting/changing/modifying the profile every single time I quit Firefox. Any ideas? And to repeat: starting in Safe Mode does nothing to solve my problem.

The only thing that worked was downloading and installing the Beta version (29.0).

Hi ptsii, it's possible this was a bug in Firefox 28 that is fixed in Firefox Beta (future Firefox 29). If the problem doesn't come back, you can mark your post as the solution for future reference.
