YouTube Windowed FullScreen από navi.jador

UPDATES!!
-More consistently loads button onto page even with ads.
-There is now a OPTIONS page with 3 new options. To go there, either click the icon in your browser, or head to about:addons and click on Youtube Windowed FullScreen and click the options tab. Please not for Shortcut Key not every key may work correctly as YouTube may block them. Most keys should work if they are not reserved.

NOTE: PLEASE RESTART FIREFOX OR REFRESH YOUTUBE IF IT DOESNT WORK AFTER INSTALLING.

A simple and lightweight extension that adds an icon which allows the YouTube video player to fill the entire page, as a full browser player. This is especially useful for dual monitor users that may wish to continue working on other tasks with a large video playing.

In other words make your youtube fullscreen in your window!
FYI the shortcut key to toggle this without clicking is "`" on your keyboard! Change these in settings at about:addons

Updates:
1. Now works with the new youtube layout!
2. Fixed compatibility issues with MagicActions and Adblock
3. Added shortcut key "`"
4. Added Options page at about:addons, for 3 new settings (Auto-Toggle, Hide Full Screen and ShortCut Key)
