Rated 4 out of 5 stars

Just freshly installed and I love it.
It works fine with Panoramic view and on any website that I've tried it on. Only downside is that it doesn't capture Java based items such as any video on Youtube.
All-in-all, it's quite handy and more than a "glorified prt sc button".

This review is for a previous version of the add-on (2.0.1-signed).
