I can also confirm this is true. Not working for me either.

Works fine with Firefox 133.0

I'm having the same exact issue. I don't want to move up to a modern version of firefox because it would ruin my set up for making my computer look like if it's straight out of windows XP. I am using the same version of firefox as you and I have no idea what's causing it. I tried adding exceptions and everything but nothing seemed to work. I really hope that they fix this issue.

My mistake. I use version 113.0.2, but I still have the same exact issue

Try latest version, maybe fixed
