No, I refreshed it with the refresh button.

Anyway, I later went back in one of the chats on Firefox and again it didn't show me. I do think it's a local problem though, as I have seen Firefox work.
I changed like... 1-2 settings but I can't say which ones offhand (I'm on another computer right now) so later I'll revert the settings and see how I do with the default.
No one could see me though.
