Sorry for my English.
A new button with a "cogwheel" icon will appear below the video player. When you click the button, a panel will show up with three options:
You can choose your preferred playback quality which is set automatically when the video loaded. Beside the standard resolutions (144p, 240p, 360p, 480p, 720p, 1080p) there are two special options:
|AUTO||Let the player choose the proper quality. (default)|
|ORIGINAL||Set the highest available quality.|
Please keep in mind that YouTube tends to override your preference when you switch to fullscreen and you have chosen a quality below 720p.
You can set the default player size to:
|AUTO||Let YouTube handle the player size. (default)|
|WIDE||Set the wide size as the default.|
|FIT||Set the player width the same as the page width, keeping the aspect ratio.|
You can set the default playback state:
|START||The video starts as soon as possible. (default)|
|PAUSE||The playback is paused but the player keep buffering.|
|STOP||The playback is stopped and the player doesn't buffer either.|
|AUTO PAUSE||Like PAUSE but only for videos opened in a background tab, and also the playback will automatically be started when the tab gets focus.|
|AUTO STOP||Like AUTO PAUSE but the playback will be stopped instead of paused.|
"It would be great if I could disable annotations permanently."
