Add-on summary

This extension enables YouTube to default to theater mode for the player, even if you're not logged in. If you prefer the default mode, you can easily switch back by clicking the button in the player or using the "KeyT" shortcut. However, the next time you visit, the player will automatically be in theater mode again. The extension doesn't offer any configurable options; it functions seamlessly. It's important to note that the theater mode activated by the extension is authentic and not achieved through CSS or JS tricks; it uses YouTube's actual theater mode.

To use this feature in incognito mode, you must allow the extension to be active in this mode.

How does the extension work? The extension employs two methods to ensure the player is in theater mode:

  1. It sets the relevant cookie on each visit.
  2. It triggers the necessary button press when the player loads.

doesn't work. 1 in 3 videos or so still are in small windows even after manually forcing the theather

Fantastic extension. It does what it says, and it does it natively, which means theater mode just happens--no weird resizing glitches to wait for. The app uses the minimal amount of permissions possible. Well done.
