4:3 Aspect Fixer (Simple)

Adds simple 4:3 correction and zoom-to-fill buttons to YouTube.

An extension that adds a button into the Youtube UI that will take 4:3 content that was stretched to 16:9 by the uploader and force it into 4:3. I personally use this on a 4:3 monitor which has a secondary effect; the content aspect ratio is fixed, however half the screen real estate goes unused because the content still does not fit the screen. To fix this I have added a zoom button that will fit the content properly for a 4:3 display. To use, just hover your mouse over any youtube video you wish to fix, fullscreen the video first if you wish to use the zoom feature, click the 4:3 button to fix the aspect ratio, and then the content will display correctly.
