What is a DUMP file?
Crash log generated by Google BreakPad, a crash reporting tool used by Mozilla Firefox and other programs; may be saved by the program to the user's local file system when the program crashes, along with .EXTRA files.
DUMP files can be submitted with EXTRA files to the software developer so that the cause of the crash can be determined.
NOTE: DUMP files generated by Mozilla Firefox are saved to the [user]\AppData\Roaming\Mozilla\Firefox\Crash Reports\pending\ directory.
