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

This extension forces YouTube to open its player in the theater mode (theatre mode) by default, even if you are not logged in. You can simply switch back to the normal mode by pressing the button in the player or pressing the "KeyT" shortcut, however, on the next visit, the player will be in the theater mode again! The extension does not have any options. It just works. Note that I am not using CSS or JS tricks to simulate theater mode. This is the actual theater mode that YouTube offers.

To have this option in the incognito mode, you need to allow the extension to be active on this mode.

How does it work?
The extension uses two methods to make sure the player is in the wide-screen mode:
1. Set the relevant cookie on each visit
2. Press the relevant button when the player loads.
