Firefox Screenshot Tool

Hello,

I recently started using the firefox screenshot tool and was wondering if something was possible with it. Here is a screenshot of me using the tool within my companies online software. You can see that the blue box from my software has
a scroll bar on the side, and when I hover over the element to take the screenshot with your tool, it even recognizes that the frame goes beyond what is visible. I was wondering if there is any way that the screenshot can capture what is not visible. As the
“Save Full Page” option seems to handle this on pages that scroll down, I would imagine this is possible.

Basically, instead of getting a result like the left image (using your tool), I would like a result like the right image (a splice of two images using the Windows SnippingTool)
