Yes

无法滚动截屏，只能截当前看到的部分。

Can't access the add on.

The addon seems very shady, the whole screenshot with alot of permissions, based in bejing. claims 2 million users, but i will be one less

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
