Impossible to read any pop-up window on Firefox

Any time I click on an option that opens a pop-up modal to fill in details, it’s impossible to read it as it’s almost entirely see-through.

I did a quick test and this behavior does not happen with Chrome

I don’t see this with Firefox (143.0.4 (aarch64)) on MacOS 26 Tahoe - behaves just like it does on Chrome.

I’ve seen this on both Windows and Mac, also on 143.0.4 (aarch64)

Might be a plugin I’ve got, I’ll see if I can narrow it down.

I have tried to tone down the horrible Glass effect in Tahoe. Maybe that’s why I don’t see the transparency…
