The problem seems to be caused by the BTTV extension. Even though this tool is very useful when managing emotes, having it installed will impair your ability to watch streams in full screen.

Please read on to find out what you can to do temporarily bypass the issue, and get back to watching your favorite streams in full-screen mode.

How to fix full-screen issue on  Twitch?

1. Try a different browser

If full screen isn’t working in Twitch, it’s possible that your browser is the issue. To check that, you need to switch to a different browser, such as UR Browser for example.

UR Browser is built on Chromium engine, so it’s quite similar to Chrome. In fact, all your Chrome extensions will continue working in UR Browser as well.

Unlike Chrome, UR Browser focuses highly on user privacy and security, and it comes with tracking and malware protection. In addition, the browser has a built-in VPN, for an extra layer of security.
