I'm not talking about the the main notification bell. I'm talking about the bell that you find on individual channels that allows you to select whether or not you want to receive notifications when those channels upload content. When I click on the bell, the grey selection circle appears, but the menu doesn't pop up. This is only happening in my Firefox browser. I tried disabling all Firefox add-ons, but that did nothing.
更新1:
I know it's working for others in their Firefox browser. It's just not working in mine for some reason.
更新2:
It randomly started working again. I didn't do or change anything else, so I have no idea what happened. Just a weird bug, I guess.
