Middle click not working

I switched to Firefox DE because I wasn't able to install 3rd party extensions. Just now, my middle click isn't working. I can't use the middle click to open/close tabs and to open links in a new tab. I checked my settings, tried a new profile, nothing works except in normal Firefox, the middle mouse does work, but I don't want to switch to that. My middle click also works in Edge and other apps, but please fix this issue as soon as possible. Thank you. PS. Please add biometrics to Firefox, like how Google did with Chrome.
