This is the best screenshot add-on that I have found for Firefox. I see some people are having issues, but it works great for me.

Literally awesome! Really enjoying the experience with this.

Very helpful extension, and easy to use.

It's very usefull and handy as well. Congrats to all developers!! Thanks!!

This add-on is an amazing tool to have in your arsenal. Super easy to use and mega useful on a daily basis. Everything run smoothly (unless you create too many annotations on the same screenshot with many tabs opened). Considering upgrading to a paid plan.

A daily staple. Thanks folks.

great, best i have used, highly recommended

One of my trusted Useful addon

User-friendly and very flexible

I really like it because it is easy to use and always at hand!

Simply perfect. My best choice for this function.

So practical and really easy to use. Great thanks to the developers!

I especially love the immediate notation before download/save. So helpful when explaining things to non-technical users/clients. Awesome Screenshot is Awesome!

Awesome Screenshot is just awesome. Best feature is taking shot of the entire web page, not just what you see on screen. It works consistently well in Firefox.
