Hi,

I haven't been able to reproduce this issue using Firefox 63.0 or Firefox Nightly 65.0a1 on Fedora, Ubuntu 18.04 or Windows 10.
All three screenshot-taking methods work correctly for me.

Could you test if the issue is reproducible in safe mode, here is a link that can help you do that:

If the issue still occurs please try using a new profile, you can find the steps here:

Thank you for reporting!

Thanks for checking.

I did reproduce on two friends Windows 10 computers.

I did reproduce after restarting in safe mode (all add-ons disabled).

Creating a new profile, fixed the issue for me.

Thanks!

Screenshots (and the devtools screenshot tool) can only take full page screenshots when the page itself is scrollable. If there are elements inside the page that can be scrolled then we aren't able to take full page screenshots of that (or rather, the "full page" is just the visible viewport). In each of these sites there is an internal element that is scrollable.
