We seem to suddenly be experiencing two issues seemingly linked to Firefox or Firefox-related browsers.
The entire chat function has disappeared for users. The speech bubble icon has disappeared and if users are tagged in chat a blank space appears in the notification list. The list of chats and DMs has also disappeared from the left hand menu (under the different forum sections).
Users are unable to vote in polls. The options are displayed but the check box next to them is non-existent or just a ‘dot’.
