Unusable, can't make the page overlay that it creates to go away.

无法滚动截屏，只能截当前看到的部分。

best screenshot making addon
wish other browsers had something like this
only reason why I still use firefox

Choosing whole web page only captures visible area. Other two options work well.

Does exactly what I wanted it to do, screenshot a selectable area WITH scrolling, but without a bunch of extra's like uploading to cloud or going through some service, simple, and works.

Many screenshot tools allow select-able areas ,but not if you have to scroll, others will work ,but manage to capture "floating" elements that then ruin the shot.

This one just simply works

Very good. Simple. Just a missing : the ability to choose the output format of the capture : jpg or pdf instead of png. A tip : scroll from down to top for best result
