One moment I was using Firefox the same as I always have. The only difference was that I changed the preferences to erase history when quitting Firefox. When trying to open the program again, it is immediately unresponsive. I attempted opening it in safe mode and a window will appear but never load, and Firefox remains unresponsive. I could not reset Firefox either. I deleted the application and re-downloaded Firefox, but it changed nothing. I am in OSX 10.7.4. Can anyone help?

Hello chillman4130, try to create a new profile(in case that you profile is corrupted), go (with closed firefox...... it is anyway) to /Applications/Utilities > Open the Terminal application > in the Terminal application, enter the following:

  • /Applications/Firefox.app/Contents/MacOS/firefox-bin -p

Press Return

the above opens Profile Manager, if the profile manager open then see : Creating a profile

then see: Recovering important data from an old profile
