Light/Dark theme auto switching Firefox

Hey All

I am running Firefox on pop!_OS and have an extension that switches my themes between light and dark. It works really well and have set all my apps to follow system theme. I am running Firefox and it does switch well and my Lemmy setting is set to follow the browser. It was working well for a long time, but the last two months I have noticed that lemmy does not auto switch the theme. Is there something I can do on my end?
