Ever had the problem where you simply can’t stop accidentally closing a window, and the website programmers won’t prevent you from doing it? You can fix this problem with a tiny, simple application. Use Ctrl+1 to toggle the Close button on/off, or add it to a rule so it’s always disabled.
Hah! I just pressed the keystroke in firefox and jumped to my gmail tab!
@chris: Yeah, in Firefox it jumps to the first open tab. Ctrl+2 is second, and so on.
