Full Page Screenshot Not Working

[rammjet]

Firefox 150.0 on Linux Mint.

Tried several times to take a full page screenshot and every time it only took what was visible.  Yes, I clicked on Full Page.

This is bug 1643719. You can see in the screenshot that the scrollable area is the main/bottom-right region of the page - the page itself is not scrollable. So we would need to guess which part of the page to scroll and how to assemble a single image with it. Should the left toolbar get stretched to the full height? Or just left hanging. Its a surprisingly subtle problem. That said, we can probably do something that gives you the expected result most of the time for most pages.
