Rated 5 out of 5 stars
The best screen shot grabber I have found for firefox so far.
It is not too complicated - either full screen or drawn box but that is what I want.
As for the 'large space on toolbar' someone complained of - it is just a toolbar button. Move or remove it as normal. I just use the status bar button myself.
One feature request. Would like option to simply open screen cap in its own tab. That would make it easily available for a wide number of other plugins to act on or play with immediately.
