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!

It's perfect. Thanks Manuel.

Best screenshot extensions in the shop. Saves PNG images of full page without compression!

I really like this tool, because it is fast and very easy to understand and use (also for older users, not only for experts). Thank you!

一键全网页截屏 很好

I just tested about 6 or 7 different screenshot extensions — including the big ones like Nimbus, Awesome Screenshot, and Fireshot — and Save Screenshot by Manuel Reimer was the only one that could actually (and COMPLETELY capture and) save the huge webpages I needed to screenshot for archiving purposes. Not only was the capturing process itself much faster the others I have tested in the past, it captured the entirety of the first webpage (in one try) as a 26.5 MB PNG file without any unnecessary loading, superfluous options, or other fluff that normally gets in the way of performing what should be a simple task in a timely manner. It delivered and did everything it promised to do for me as of November 8th, 2018 on my Firefox 62.0 Portable browser — in private browsing mode no less with a VPN on without needing to tweak anything beforehand.

*Funny story about this extension:

I had been so frustrated with the repeated failures of the other webpage capture extensions that, when I didn't see an immediate reaction to hitting the screencapture button, I assumed it wasn't working like all the others and uninstalled it immediately — within seconds because I had my extensions tab open for quick access. To my dismay the "save file as" window popped up almost immediately after I had uninstalled it. I was still able to save the image despite the extension being uninstalled and immediately undid the uninstallation once I realized it had worked. Talk about a close call.

Been looking a long time for a one click-solution that quickly and correctly gets what I want done - thanks!!!

很棒！可以在安卓上使用的长截屏扩展！

It s very useful and simple! Thanks!

Gutes Tool um Bildschirmfotos nicht in die Cloud laden zu müssen, wie bei der Firefox Erweiterung.

Simple without being too simple - this addon creates a whole page screenshot and then shows a download dialog.

просто супер ! легко ,удобно , работает !!!

I really like this minimalist app, very useful. unfortunately it stopped working in firefox 58.0 (Mac) :(
Thanks for the good work

Minimalist perfection. Don't change it. Thank you.

Superb.
Most importantly for me it allows you to capture a page zoomed out while maintaining capture resolution (i.e. it allows above native screen resolution capture). This is the only WebExtension I've found that does. I hope this never changes.

Add to that a minimalist approach without any superfluous services or tools, just capture visible/full page and jpeg/png: It's basically perfect.
