excelent

Erfasst ganze Websiten nur, wenn diese nur einen Scrollbalken haben. Ausserdem ist das Addon Mühe mit sich verschiebender Leiste (beim Scrollen). Somit ist die Leiste wiederholt auf dem Ergebnis drauf,

very good

Overall a very convenient and easy to use app. One glitch: periodically when I use Capture selection and try to save as a PDF, the app saves the selection as a MS DOS.exe file--I have to try several times before it finally saves as a PDF...

Truly great, capture selection, capture whole pages, copy to clipboard or export to pdf or jpeg.
Only thing it cannot do is capture those floating windows within windows (like for example facebook picture that you open when you click on the picture in the home page so it hovers above the home page. It would captue the homepage behind the floating windows. So for that I use prntscr)
But all else, this one is the best so far.

doesnt work
captures nothing !!!

Works most of the time to capture full web pages or user selected parts but sometimes the region captured does not correspond to the region selected and sometimes parts of a page such as columns in some tables are not captured.

Entire program suddenly vanished from Firefox 87.0. Nothing in toolbars, not listed in addons list, but this page has a "remove" buton on it still.
Turns out they listed it under "Take.." in the addons list, but the addon begins with "Full.." on the addons.mozilla.org site so you can't find it! They also used the similar "S" for the icon in the toolbar as "HTTPS anywhere" thus making it appear that the icon had vanished. After reinstalling the program there are 2 copies listed in the addons menu, one of which is shown as disabled for some reason. All of this conspired to cause suicidal thoughts.

Advantages
Can capture entire browser window including toolbars, or specific sections.
Converts to PDF instantly, very fast

Disadvantages
Not free.
Why not make it easier to get to the editor window? It's not mentioned in the docs or video.
Needs better documentation including: Videos with a narration
Written documentation needs an update as it refers to an older version

Works well, however cannot successfully take screenshots to save when a webpage is on Firefox's Reading Mode. If you use Reading Mode a lot and want to gett a screenshot of it all, you might need to look at another extension.

This Add-On works pretty good and does exactly what is advertised...it makes screenshots ;)

Firefox latest version, never worked on scroll capture. Looked through tech support responses - uninstall/reinstall, disable all other extensions. Not very useful if I have to disable everything just to do a screen capture.

A nearly perfect tool for capturing images and full pages from the web. The only way to improve it would be to add a save to ebook format.
