My esteemed listmates, This is a very serious. Normally, in Firefox when I want to take a screenshot of all that I see as I scroll down the page I press Ctrl + Shift + K and then type in :screenshot --fullpage and it captures WYSIWYG in a PNG on to my hard drive. I try that with back and forth emails in Gmail but that doesn't work. If I want to capture all the emails exchanged with a person in a gmail account normally I press Reply or Forward I can capture all the back and forty. That doesn't work with this gmail exchange. I'vde taken to snapping photos wiht my cell phone of each screen as I screen down to capture the WYSIWYG. In Chrome and The Edge I can use that Screen Devouring icon which resembles a Pac Man as it bites along the screen from left to right and captures all the scrolling down as WYSIWYG but I must use FF in this case. Is there any Screen Devouring extension for FF? Thank you for your understanding, nonjudgmental help. Charles. Charlotte County Public Library
