When working hints on Ancestry.com, under certain conditions a second scrollbar is generated to the immediate left of the right hand scrollbar. This second scrollbar is used to move downward in the hint compare area on the right hand side of the open page. When running under Firefox on Windows 11 systems "this second scrollbar is not there"! Everything works fine using any other browsers (EDGE, Chrome, Brave), but not Firefox! Works fine on Windows 10 systems. I have tried this on 3 different Windows 11 computers with the same failed results.
