firefox-bin crashed with SIGSEGV

StacktraceTop:?? ()

please post the install.rdf files that are in the directories

   /home/shirish/.mozilla/firefox/hqk033vx.default/extensions/{DDC359D1-844A-42a7-9AA1-88A850A938A8}
   /home/shirish/.mozilla/firefox/hqk033vx.default/extensions/{d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}

Then disable all extensions and see if you can still reproduce this issue.

Thanks,
 - Alexander

I have no idea how to upload the install.rdf files as if I try uploading the files, firefox crashes. I disabled all the addons but still the issue is there. If you have any idea how I can upload the files please do tell. I have tried, FF2, FF3, Seamonkey, even links2 -g all of them give the same issue. I have no idea where or what the issue is. It still crashes :(

Hi all,

Here's the install.rdf of the 1st extension requested : - This is Seamonkey

I also found I have ubufox extensions installed, perhaps they are the root of the issue ?

Uninstalling them to see if it makes any difference.

stop firefox ... move your $HOME/.mozilla directory to a safe place (backup) ... and start firefox (aka with fresh profile).

I did mv $HOME/.mozilla $HOME/.mozilla.backup1 & still it crashes. I get the same error on the CLI.

Segmentation fault (core dumped) :(
