Thanks for the bug report. Could you please go to about:support, click "copy text to clipboard" and add it as an attachment to this bug? Thanks.

The profile seems to indicate texture upload is causing the jank.

Some notes on this jank: It occurs when scrolling past this image which is about 10MB...and firefox does not like it at all! Just opening it in a new tab and panning around is causing some pretty bad jank. I have opened larger images in Firefox before with no problems, something must be special about this image. When I remove it in devtools, I can scroll the page just fine.

The component has been changed since the backlog priority was decided, so we're resetting it.
