Bug Description

When Firefox has been running for a few days, with tens of tabs loaded and has started to run slowly, maximising or minimising a YouTube video can wedge it.

The audio keeps playing until the buffer is exhausted, but everything else is hung: no repainting of the window, no response to keyboard input. CPU usage does not fall to zero, but to around the steady state level it was at before the YouTube page was opened.
