I've used this extension for a long time now on my PC and Mac. I enjoy using it.

功能上和chrome插件相差很大，无法保存pdf

isn't working on entire page

When it works, it's great but there are too many times when it doesn't work for me! :(

I'M STILL LEARNING, BUT SO FAR I'M LUVINIT~!!

This add-in does everything that it advertises. Save a great deal of time and frustration.

Powerful, but simple and quick to use. Very good add-on!

Very good app...been using it for years, never let me down!!!!

Excellent Full screen and web-dev screenshot ability, as well as excellent save ability.

Excellent but clear capture and crop software with a fast learning curve.

It used to work in FF, but no longer. Dead in the water, does not respond. Webpage says it is only for Chrome. Too bad, I liked it, but I won't use Chrome (because Google).

Great tool. Can markup web pages, add info and use on your website or blog.
