Hi, I had the same issue, and 'ubuntu modifications' did resolve it so thanks!
A couple of things to add in case they help: For me the issue was not triggered by the update itself, but by me disabling an addon I had installed. Removing or reinstalling/reenabling the addon after that made no difference. What did help (temporarily) was removing all profiles. If Firefox could find no saved profiles when it launches, it worked - until the next restart of course, because then a profile was already saved. As for your workaround (thanks again), I'll only add it is a 'recommended package' for me, I cannot install it from within Firefox. Once installed with 'apt-get install xul-ext-ubufox' it appears as an installed extension and can be disabled (didn't try) from within Firefox.
