When I'm on the Hotmail website, I can't quit (Command+Q) the Firefox browser. This never happens with any other website. Very irritating that a website has more power than my browser. Please advise!
This can happen if a text area or plugin has focus.
Did you try to click on empty space on that page to set the focus elsewhere?
Yes, I did (and did it again just now to make sure). Doesn't make a bit of difference, unfortunately. Other ideas?
