Was using Firefox then shut it down. Opened PhotoImpact Pro 13 and was using that when about 10 minutes later I reopened Firefox. It crashed without opening. Couldn't get it to start. Other browsers worked fine. Searched internet, tried resolutions like: Restarting PC, refreshing FIrefox, troubleshooting PC, starting Firefox in Safe Mode (wouldn't start), deleted Firefox, did clean reinstall, nothing worked. Even replaced wifi net connection with cable, in case wifi adapter was interfering somehow.

I'm running Windows 8.1 64-bit.

Hi, we're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

  1. On the keyboard, press [Windows] The image "Windows key" does not exist. + [R]. This should bring up a Run window that contains a text field.
  2. In that text field, type %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!
