Enfin une extension capture d'cran qui fait ce qu'elle annonce (totalité de page). Efficace et simple Parfait !

非常好，希望移动端也可以手动截图

This extension did take screenshot of the entire page for me. Also recommend enabling 'devtools.command-button-screenshot.enabled' in 'about:config' as described by another user below, but that workflow would be less convenient.

Наконец-то контекстное меню, по экрану и сразу большой выбор варианта Скриншота !!!

This is EXACTLY what I've been looking for in a screenshot tool! (I've looked through many screenshot tools. Too often they involve arcane approaches to screen captures -- or, more often, just don't deliver what they claim to do.) Really glad I found this. Thanks Manuel -- nicely done: 5-STARS

A huge change/update to this addon. I like this.

This is the ONLY, absolutely ONLY Screenshot Addon which I have found that really works. I have tried ALL of them, methodically. Many do strange stuff like zooming in and taking screenshot only of the left side of the page, another was taking well the width but not going till the bottom, another was not having the option for full page, etc.
With this you can do ALL, full page, selection, visible part, perfect.
Thanks Manuel :)

Firefox default tool refuses to take lossless screenshot of long pages (.png or lossless copy). Sounds crazy, but it's true - you can read the issue "Ignore the PNG to JPEG Cutoff Limit...". This addon can be used as a workaround. Another workaround is to use developer tools screenshot (devtools.command-button-screenshot.enabled in about:config).

Format string similar to default tool is "Screenshot_%Y-%m-%d %t".

I just installed and have only used once to copy a full page to clipboard - but it worked like a charm! No scrolling, just click the icon, choose what type of grab you want, presto, done. If it works this well once I've used it more and with different types of grabs, I'll certainly come back and give it five stars and a rave review.

Thank you for creating this!

Очень удобно. Ничего лишнего

Really amazing. Capture a scrolling page without the page scrolling before our eyes!
This add-on would be wonderful for Chrome (Skype) too ...

a refreshingly simple screenshot extension which does its job well.

I like how it has no extra bloat, it just efficiently saves a screenshot of the entire webpage or current viewport depending on your needs.

The best part is, it is open source, so you can see how well made it is for yourself! :)

Very good extension!
Author did react very quickly to a reported bug on Github, thanks!
