Not often, but twice already I have been watching a show when all of a sudden firefox simply shuts down for no reason. It is not difficult to restart the program where it left off, but this could point to a more significant issue.
Indeed. I have seen this too. We have a new version of the system that's just been released, per http://forums.neurostechnology.com/index.php?topic=9592.0
which I'm in the process of testing myself. It's supposed to improve stability on several fronts (hopefully including this one)
