Last week as usual I updated using software updater, ever since then Firefox has been crashing every few minutes. I have uninstalled and reinstalled it and still get the same issue.

This report also contains technical information about the state of the application when it crashed.

Can't figure out what's causing it to crash.


I can guess the cause of the crash is a addon:

error Add-ons: ubufox%40ubuntu.com:3.0,%7B972ce4c6-7e08-4474-a285-3208198ce6fd%7D:39.0,langpack-en-ZA%40firefox.mozilla.org:39.0,langpack-en-GB%40firefox.mozilla.org:39.0

Usually when Firefox updates these need to be upgraded, and this is usually done automatically, but in this case it won't. To try and fix it:

  • Start Firefox in Safe Mode - you can probably also do this using the command
    firefox -safe-mode in terminal, and then selecting Safe Mode. Then try to uninstall or disable the problematic addons in the Extensions/Languages sections of the Addon Manager. Close Firefox and open it again to see if it worked.

  • Make a new profile (use firefox -P), or reset firefox (use firefox -safe-mode again, but select Refresh). This is issue probably is just with the one addon so I would recommend trying normal Safe Mode and trying to disable it first.

  • thank you, it now stops crashing, it seems that there was two different issues of flash so it had the conflict issue i guess :) i will save this incase i get same issue again! – Rhian Griffiths Jul 18 '15 at 20:42
