The screenshot feature can't capture the full appearance of scrollable interior regions of a page. If the mail site has a simplified print layout (some sites use an overlay, others pop up a new tab or window), that probably would work better. Otherwise, some style hacking might be needed (someone with a Proton mail account would need to get hands on with it).

Hi!

"The screenshot feature can't capture the full appearance of scrollable interior regions of a page."

I do not get it :) Page is rendered (all items are in DOM), so the only thing that mozilla must do is to take a complete screenshot of the page. Where lies the problem? If there is an overlay/commercials/pop up - mozilla should screenshot those things also - everything that is visible at the page/screen.

Can't you extend the selection of the area to include in the screenshot by dragging the bottom border?

If that text is in the DOM then you can use "Screenshot Node" in the context menu in the left panel in the Inspector.
