Thank your for reporting this problem and for helping improve Ubuntu. I believe this may be a duplicate of Bug #192888. Do you have flashplugin- nonfree installed? If so, try removing it with Synaptic and see if you can still duplicate the crash. I experienced similar problems (seemingly random Firefox crashes) and resolved it by using a beta release of flashplugin-nonfree. The crashes are gone, but I can't say that the beta of flashplugin-nonfree is without issues (namely video quality). If you are interested in using the beta release of flashplugin-nonfree, see attached.
