Let's say I fat-finger a url (e.g., Facebook..com), or I type "fac" into the address bar and either miss the down arrow or hit "enter" before the websites containing "fac" appear in the drop-down. I realize my error immediately, hit "ESC"... and rather than stopping, Firefox continues on to the error message ("Server not found: Firefox can't find the server at www.facebook..com") or the search results (First Acceptance Corporation, according to Google) until that page finishes loading. This wasn't an issue with older versions of Firefox--actually, it was one of the reasons I preferred Firefox to IE, since all versions of IE always behaved as I described above. Is there a reason newer versions of Firefox can't stop loading a page immediately upon my hitting "ESC" the way older versions did perfectly? More importantly, is there something I can do to get my forced upgrade of Firefox to replicate the good user interface of previous versions? It's not a huge issue, but it's irritating and seems like a step back.
