the best one i ever used

Just the best web screenshot add-on to me.

For taking full-page screenshots, this program is fantastic! It allows screenshots from URLs and other features but I haven't tried them.
The interface is very clear and structured. Simple and effective. You can save as an image or PDF, copy to the clipboard, or print. A must-have.

Son los mejores!

Works great for my ESL students. I can capture and print an image of their Kahoot scores to share with them.

Anda perfecto y simple para lo que se necesita

This works exceedingly well; I especially like that it saves the visual representation in a PDF (unlike trying to "print" it to a PDF). Recommended.

This thing is just great!

What a great extension! I use Fireshot almost daily and am grateful for its ability to capture really long passages of text.
