I'm install the firefox20 ,it often starts with the Mozilla Crash Reporter,but in the guest session it work fine.I think it must be something wrong on my configuration files, but even when I delete all the configurtion file and other ralated files with firefox to reinstall firefox ,it also starts with the Mozilla Crash Reporter,how should I do to make my firefox work fine ?

This doesn't look like a Firefox bug. It's crashing inside libfcitx-gclient.so.0.1

[csslayer (wengxt)]

this is fixed upstream for long time. 4.2.4.1 is the last version with this bug.

[Aron Xu (happyaron)]

12.10 is not supported anymore, and upstream has replied to this specific problem, please upgrade to a newer release to see if this crash still exist. Thanks.
