I tried downloading a fresh copy of Firefox, but it didn't help. I also tried starting in Troubleshooting mode. Here's the ID of one of the crash reports: 790A4DDA-72FA-44A6-BF81-E6F8D126D507

We're sorry to hear that Firefox is crashing when you open it. Please do the following to give us crash IDs that will help us understand more about the crash.

  1. Click the Finder icon in the dock. On the menu bar, click the Go menu, hold down the option or alt key and select Library. A window will open containing your Library folder.
  2. Open the "Application Support" folder, the "Firefox" folder, the "Crash Reports" folder and finally the "submitted" folder.
  3. Open the 5 most recent files with a text editor and copy the IDs.
  4. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.
