Sam,  can you also indicate what versions of plugins you are running.  you can find this by typing about:plugins
> firefox has been closed

can you also check for any resent crash reports?

type about:crashes in the location bar to see a history of crashes.

if you can paste the crash report ids into this bug.
As requested, list of plugins

about:crashes shows one crash from 2009 which is pretty old one so not relevant

Is this report still useable after 2 years ?
