Indespensible, but 1.4 is flawed Rated 4 out of 5 stars

This is an indespensible add-on, but as many have pointed out, 1.4 has problems. I won't repeat them, but I'll add that I don't like how firebug windows are now shared across all tabs that have pages open on the same domain -- whether you want this behavior or not (not sure whether this changed in 1.4 or 1.3). Used to be that each tab was treated as its own instance, which is how it should be. A lot of real estate is wasted now on tabs where I don't want/need firebug open. I'd really appreciate having firebug revert to its one-instance-per-tab behavior.

This review is for a previous version of the add-on (1.4.2).
