random pages make firefox crash

[Guybrush88]

Binary package hint: firefox

i noticed that when i open any type of web page firefox exits without any explanation mask forcing the user to restart firefox. i don't know exactly how to reproduce that. if it can be useful i use the latest gnash plugin for firefox. one of the sites i experience most this error is the italian version of wikipedia (www.wikipedia.it) when using the random voice link.
i use ubuntu gutsy

could you start firefox from a terminal and include the console output when firefox freezes

do you have anything in the /var/crash directory concerning firefox, if so please double click on it in the nautilus file browser - this should start apport which will send useful information about the crash

Hi,

   could you try to reproduce with the following changes

   1. make sure you're using the Human theme (System->Preferences->Appearance)
   2. turn off the the visual effects (System->Preferences->Appearance)
   3. start firefox after having entered the following in a console : export MOZ_DISABLE_PANGO=1

   thanks,

      Koen

doing your changes, koen, and opening firefox from terminal it says this:
davide@Linuxster:~$ export MOZ_DISABLE_PANGO=1
davide@Linuxster:~$ firefox
