Excellent. Allows full page or selected area screenshots in to various formats. Simple to use.

Takes a few seconds to capture the website, so be patient :) Then offers the option to save as pdf, image, copy to clipboard etc. Works well and is flexible with options.
It can be triggered with a button from the toolbar, which is good for capturing mouseover and popup texts which would disappear with right click - take screenshot.

A real working fullpage screenshot Add-on

This is quite the best browser screen-shot saver I've come across. Thoroughly recommended!

Created an empty file after taking longer capturing the page then competitors, competitors also don't push another lite version down your throat. I tried this thinking the negative reviewers must be stupid given the majority of positive reviews, I was wrong. Don't make my mistake. Go somewhere else.

К сожалению не может сделать скриншот с прокруткой текста решения в гас правосудии (например - https://bsr.sudrf.ru/bigs/showDocument.html?id=3_f434687b44db6739ce986e5b8cfe4427&shard=%D0%92%D1%81%D0%B5%20%D0%B4%D0%B5%D0%BB%D0%B0&fieldName=case_user_document_text_tag&from=p&r={%22id%22:%223_f434687b44db6739ce986e5b8cfe4427%22,%22hlColors%22:[%22searchHL0%22],%22uid%22:%228456f599-6e0c-4b57-9f17-e1c445061121%22})

This is the first full-screenshot plugin that works perfectly with scroll pages. Wow!!!

It's the best I've tried and I really recommend it!

Hasta funciona genial en Kubuntu 20 es genial :D

This addon no longer works. After several months of use, the plugin scans the page but does not save the screenshot to a file. The problem also occurs with other users, which can be checked on the forum and unexpectedly, buying the pro version helps with this problem. It's over for me
