There is a bug in Firefox Browser where it doesn't allow you to scroll up in the chat during the livestream and keep your place there to read a message. It auto scrolls down to the new messages everytime a new message appears in the chat. Firefox is the ONLY browser that does this so it must be a bug. Chrome, Edge, Opera, Brave, etc none of these do this. It is especially problematic in livestreams with many viewers and an active chat, making it impossible to read a previous message if you want. It happens on all platforms, twitch, kick, YouTube, Parti, Rumble, anything with a live chat
