Sorry to hear about the crashes, and thank you for the report ID: https://crash-stats.mozilla.com/report/index/3f1e4f58-369b-4278-b6a1-8ca0a1170920 Unfortunately, I am not personally able to extract anything from the report to solve this problem. Are there particular circumstances where Firefox crashes? If this occurs frequently, could you test whether it occurs in Firefox's Safe Mode?
