Is Refined GitHub safe?

Low risk

Refined GitHub fetches version-specific CSS from refined-github.github.io and injects it into GitHub pages.

When a supported GitHub or Gist page loads, the extension asks its background script for a style hotfix. The background script retrieves CSS for version 26.7 from refined-github.github.io/yolo and, if present, prepends it as a page style unless the page is GitHub Enterprise or a development build.
