mma-blindfold от ActivityWorkshop

On the wikipedia.org domains, a new page icon appears allowing you to switch the blindfold on and off. This status is stored in a cookie so you can navigate around Wikipedia keeping your blindfold on. When off, the pages are unaltered, allowing you to see all results. When activated, the results tables on all pages (if found) are altered to hide the winners and losers (by randomly swapping the competitor names) and the win method / time are deleted. A green sidebar is added to make it clear whether the blindfold is on or not before you scroll down.
The extension has been tested with a variety of Wikipedia pages but may not support all organisations, or pages about all combat sports.
