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

Best in Show! Flawless as far as my experience with it goes!! Thanks for an add-on that makes the internet that much more useful !

Great "NO BS" screenshot extension.
Very intuitive yet flexible interface. Not loaded with ads or bloat.
Default naming scheme is excellent for captures.
Been using FireShot for a little over a year now (2020) and it is one of my core extensions I add to my browser upon spinning up a new machine. Can't live without it.
For a free extension there is no comparison, IMO.
I don't write reviews normally but this one deserves one. Just hope it stays this way.

Best screenshot addon i've seen so far. Good work!
