Firefox crashes

A "crash" is what happens when Firefox closes unexpectedly. After a crash, the Mozilla Crash Reporter will appear, asking if you want to send technical details of the crash to Mozilla for processing. This article explains how to get help with your crash in the support forum and directs you to articles about specific crash symptoms.


Processed reports are given a crash "signature" which is often indicative of what caused the crash. Because there are so many possible causes for crashes, the best way to get help is to post your crash signature in the forum or live chat.
In the Firefox Location bar, go to about:crashes. A page listing crash reports that you've submitted will appear.

1. • If you cannot start Firefox, see Firefox crashes when you open it.
2. Click on the latest crash under Report ID.
   
   
3. You will be taken to a page on crash-stats.mozilla.com, saying that "Your report is being processed". When it is finished processing your report, the crash signature will appear under the ID. (e.g. nsCrasher::Crash())
   
   
4. In the top right corner of the page, click on Search Mozilla Support for Help to search for Support articles that match the crash signature.
