My firefox application crashes on closing half a dozen times a day.

I'm running Kubuntu 14.04.2 (Linux)

Firefox 39.0

I tried changing Firefox settings to suppress the reports but to no avail.

Hope someone can offer advice or help me to troubleshoot this since I have been unsuccessful using my own resources and limited knowledge.


A similar problem, due to add-on and plugin incompatibility - crash only on closing Firefox - happened in my Windows installation. To confirm it's an extension issue, restart in Safe mode.

If that solves the problem, then enable half your extensions, to see which half the troublemaker is in. Then in that half, enable only half of those left (i.e. one quarter of the total). usw. This binary search found the culprit (a download manager that needed updating) quickly for me.
