Several days ago i updated my Ubuntu «Gusty Gibon» installation. And after that Firefox keeps crashing randomly, saying ``Floating point exception`` in console.
The reason of this issue seems changes in libcairo2 made by security update. Latest version of this library is libcairo2_1.4.10-1ubuntu4.1. Downgrading it to libcairo2_1.4.10-1ubuntu4 fixes the problem.
The bug is reported already and I hope libcairo2 will be fixed soon. But untill that moment sudo apt-get install libcairo2=1.4.10-1ubuntu4 can help.
UPD: Issue is fixed in 1.4.10-1ubuntu4.2:
libcairo (1.4.10-1ubuntu4.2) gutsy-security; urgency=low
