I’ve used Firefox on YouTube and Twitch for thousands of hours over the last years… never an issue. Doesn’t matter if it’s normal videos, memberships, live streams, chats, Prime rewards, reward drops, uploading videos to my own channel, …

Actually there was a small issue with live chats on YouTube having a memory leak, but that has been fixed for over a year now.

That sounds like someone who has never even used Firefox in the last 10+ years. What the hell dude.

Show me a popular website that doesn’t work in Firefox.
