Using Windows 10, 64 bit system. My problem with Firefox and Wordle is similar. Only the top (blank) squares are shown. The bottom half of the game, that shows letters of the alphabet used and remaining, does not appear and cannot be scrolled down. I know this is Firefox as I tried it on Google Chrome and it works just fine, with all elements appearing. Please fix.

I need to disable Enhanced Tracking Protection via the slider in the padlock drop-down list to make the Wordle page work properly. If you have other content blocking extensions then you may have to disable those as well.
