I believe this is my favorite add-on, so that grants another review from my part.

"I screamed foul curses for the last time. What the hell kind of shortcut layout is it that closing a tab is next to quitting the whole program?"

-- Same thing is true concerning Simple Scan (Ubuntu): the page-scanning shortcut (ctrl-1) sometimes causes finger to slip on the Q key and therefore exit the program and throwing all the current project away without any fault tolerance.

This review is for a previous version of the add-on (20110831). 

Does what it is supposed to be doing, under Linux at least. Rated 5 out of 5 stars

Another way to implement such a protection against the CTRL-Q shortcut feature is:

Depending on the circumstances of your current browsing conditions, you might like one better than the other. Personally, having tried both, and in retrospective, I like this one better than "always ask," which, like the title says, always asks upon browser exiting, even through CTRL-W-ing, which may be obtrusive at times.

Very useful. Mozilla should really disable that one shortcut by default, though. Or, at least do something about it.
