One of our users was experiencing a lot of crashes in Firefox v25.0 The
browser was relatively up to date, had been uninstalled and reinstalled a couple
times and was even updated to the latest version from Mozilla... all to no
For reasons that aren't clear to us, it turns out FireFox was creating
thousands of Crash Reports which were "clogging up the system". A bit of digging
revealed 88,955 crash reports totalling 2.56GB worth of data!! In the end, we
solved the browser instability by manually deleting the entire Crash Report
folder, as going to - History > Clear Recent History > Time Range to clear
"Everything", check all boxes > Clear Now - only caused the browser to
have a heart attack and restart.
If you have a similar unexplainable crashing issue with FireFox, 1) check
your system for a build up of crash reports, then 2) disable crash
To disable crash reporting in Firefox: Go to Tools > Options > Advanced
> under the Data Choices tab uncheck "enable firefox health report" and
uncheck "enable crash reporter" > OK.
To manually delete FF Crash Reports, go
delete everything in that folder.
