Simply interacting with the firefox window, like moving it around or resizing it, seems to cause it to freeze up, and when it does, so does the rest of the gui, including local apps and the taskbar, etc. firefox seems to be the only app over ssh that seems to cause it so far, xeyes and other things don't.
Something that might be related, is that when I am connecting to a mint debian machine over ssh, and try to launch something that asks for permissions, such as synaptic, it freezes everything up to the point that I have to ctlr-alt-f1 and kill the ssh terminal just to get everything to work in ubuntu again. This might happen if the host is something other than mint debian, but I haven't had a chance to test that yet, or try it on a different ubuntu client either.
