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.

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!

ok thanks, so it really appears that they didn't get submitted. without a successful crash report it will be very difficult to give any advice other then generic hints like trying to perform a scan for malware with various different tools or trying to perform a clean reinstall and/or starting with a fresh firefox profile.
