@TeamYouTube I'm regularly finding the chat box in live streams and replays crashes the browser tab in @Firefox 68.01 (32bit) in Windows 10 pro 64bit version 1803 build 17134.885. Just me, or is this a known issue?
Good to know it's working on other browsers so far. Since this is only happening on Firefox we suggest you try reinstalling the browser. Can you also submit this using our feedback tool? Here are the steps: https://yt.be/help/feedback
