Firefox browser used to crash more often in older days not that much with version 56+, the browser has way improved in performance and stability. The new Firefox crashes less these days, whenever Mozilla browser crashes due to a script or web page, the browser disappears and Mozilla Crash Reporter pops up and asks the user to send the crash report to Mozilla, so that the Firefox team investigates the reason for the crash and fixes the issue in future versions. Mozilla Crash reporter offers the options to restart or quit Firefox browser.

you have to open wordpad as administrator and then edit the (application.ini) file. You almost have to do any system change as admin in Windows 7. Sucks

The instructions are for Windows and they’re worked also, sorry can’t help if you’re on Linux. Check this, this might help you http://stackoverflow.com/questions/28393544/disable-crash-reports-of-firefox-in-linux
just rename crashreporter.exe to crashreporter.exe.bak and crashreporter.ini to crashreporter.ini.bak. Problem solved and now wait till the next update.
Thank you, Cooksad, for the reminder. Wordpad presents the correct formatting.
And thank you John P. Trying the .bak solution . . . until the next update which I presume requires doing the .bak solution again. It’s worth the small amount of time compared to the freezing of unnecessary crashreporting which takes complete control of all computer resources – of course at inopportune moments.
That’s my experience, too, M.G. The crashreporter takes over all computer resources and freezes it for 5 minutes. I’m amazed Firefox has not fixed this after all this time.
