What is Github Whitespace Disabler?
Github Whitespace Disabler is a Firefox add-on that forces Github to open diff pages without displaying whitespace changes.
The add-on requires permission to access only relevant Github pages, but it's only evaluating the URLs and determining whether or not to redirect to the same URL with "w=1" appended. It is not reading any content.
