Rated 5 out of 5 stars

Thank you Kevin Nguyen!
Your hack is remarkable; it works flawlessly. Brilliant coding.

This is the fastest screen-shot add-on, tiny footprint, and effective area selection.
I think you should take over the maintenance of this useful tool.

Btw, I edited the rdf file to MaxVer 24.* (just for the sake of not installing another add-on; and to not get worried editing the xpi file later). I zipped the edited jar file first, and the edited xpi file later.

Thanks again and keep it going :)
