The Problem Explained & User Frustration

Occasional bugs are unavoidable, even on a platform as large and reliable as Twitch. Fortunately, Twitch’s support team is usually quick to provide a solution for any new bugs discovered by the community.

However, some bugs aren’t considered widespread or significant enough to be priorities, so it’s up to the community to find a fix.

One of these bugs is the Twitch fullscreen not working problem.

As you can see in this Reddit thread, it’s easy for users to become frustrated when a simple feature doesn’t work. One user even created a GIF to illustrate the problem better. However, an official solution is nowhere in sight.

Fullscreen mode on any content-streaming website is one of the fundamental features for allowing you to enjoy it properly.

Let’s take a look at some of the proven fixes for this problem.

Fix 1: Use This Simple Workaround Trick

Many Twitch users prefer keeping their extensions active while watching a stream to enhance their viewing experience. Some of these extensions are designed to prevent ads from showing, while others provide a redesigned interface.

BBTV is one of the most popular extensions for Twitch. More than a few million users currently have it installed.

What does this have to do with Twitch not opening streams when clicking on Fullscreen?

According to this Reddit thread, disabling BBTV is guaranteed to solve the problem. However, many users prefer keeping the extension active while on Twitch, so how can they enjoy the best of both worlds?

A user known by the nickname”taurmice” found a simple workaround. To apply this method, follow the steps below.

  1. Open and sign in to your account.
  2. Load the stream you want to watch in “default” watching mode.
  3. Instead of clicking the Fullscreen button located in the bottom-right corner, click the one next to it, which is for Theater Mode.

  4. Now that your stream is in Theater Mode, double-click with your left mouse button on the viewing window itself. The stream will go into Fullscreen mode.

You should now be able to watch Twitch on Fullscreen without disabling or uninstalling your BBTV extension.

Fix 2: Use A Different Browser To Access Twitch

Although Chrome is the preferred choice for many millions of PC users, other browsers shouldn’t be disregarded.

Chrome is a great universal browser, used daily by countless people. However, there are alternative options available for accessing Twitch. You won’t know whether or not they are more suitable until you try them.

For example, you might try OperaGX, a gaming browser with a built-in Twitch section. Perhaps the Twitch fullscreen not working problem won’t be an issue in that browser. It’s worth finding out.

Many alternative browsers are also available. We have a comprehensive guide covering that topic, which you can find here.


You should now be able to fix the Twitch Fullscreen Not Working problem and enjoy streams the way they’re meant to be seen.

You can always use a different device to watch Twitch for an improved viewing experience if playback isn’t as smooth as you want on your PC.
