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.
- Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
- In that text field, enter %APPDATA% and press Enter. An explorer window should open.
- From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
- 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.
- Open the most recent 5 files with a text editor and copy the IDs.
- Paste each ID with bp- into the reply window on the forums.
Thanks in advance!

Solved the problem. When Microsoft upgraged me to IE 10 which screwed up my computer, Microsoft installed KB 2670838. KB 2912390 updated this fix and caused Firefox to crash. When I uninstalled KB 2670838 and hid that update, the problem went away and I am back browsing in Mozilla's arms.
