Better Github Favicons is a Chrome extension that enhances the pull request experience on Github. It provides a visual cue by changing the favicon color of each tab to reflect the status of continuous integration (CI) on the pull request. This simple yet effective feature allows users to quickly identify whether tests are passing and if style guides are being enforced.

With Better Github Favicons, users can easily track the status of pull requests without the need to switch tabs or delve into detailed reports. The color changes in the favicons provide instant feedback on the health of each pull request, streamlining the development workflow.
