Since the last update (to level 37.0.2) I have been getting consistent CTDs when closing the FireFox window (all tabs when necessary). This has been going on for some time now, so I tried to find dump files for the crashes and found none where I would normally expect to find them (c:\program data\mozilla). So: Are you having difficulty solving this problem? Does FireFox even capture exception data when it crashes? If so, where does the dump file get saved? If not, do you have a version that does? If you have one point me to it and I will download/install it and send you any dumps I get from FireFox.
