Theater Mode for YouTube™ (large player view)

Forces YouTube to open the player in the theater mode (full-width mode) even if you are logged out

Theater Mode for YouTube™ Chrome Extension

Theater Mode for YouTube™ is a seamless Chrome extension that sets YouTube's player to open in full-width theater mode by default, regardless of login status. It provides an authentic theater mode experience by using YouTube's actual theater mode feature, not through CSS or JS manipulation. The extension works by setting the relevant cookie with each visit and triggering the required button press when the player loads. It also functions in incognito mode as long as you allow it. The next time you visit, the player will automatically be in theater mode again.

Extension 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.

Немає ніякого ефекту кінотеатру. Мабуть не просто так навіть скріншота в описі розширення немає.
