Since upgrading to 8.10, my Firefox seems to have a mind
of it's own. I've used it exclusively as my web browser for five years
on Windows, Mac and now Linux, and I'll probably never use another
browser, but since I made the change to 8.10, it's really ticking me
off! Every time it opens, it goes into fullscreen mode, which means I
have to keep pressing F11 until it goes away. It's not that this is a
hardship, it's just a ball ache and it's annoying to have to do it every
time I want to see the time or navigate away from FF. Does anyone have
any ideas? (I didn't have this problem with earlier versions, by the way)
