This extension makes GitHub use the system emoji font on Linux, FreeBSD, and other non-Windows, non-macOS systems. – Details When browsing GitHub on non-Apple and Microsoft platforms GitHub performs image replacement on emoji, replacing the text with mis-aligned images of the super ugly Noto Color Emoji font. This extension alters the user agent to appear as Windows when on GitHub so that it does not mess with the emoji and uses the emoji font installed on your system. – Acknowledgements Icon made by Smashicons from www.flaticon.com.
