If you're typing in the Firefox address bar and alt–tab to a different window, then back, the entire text in the address bar is highlighted. This is extremely annoying to me. Is there a way to turn this behavior off? What I'd like to see is whatever I had when I left the application (e.g. either a selection or an insert point). My Firefox version is 3.5.3, if that matters. Thanks!
