Firefox 20 was released just two days ago, but Mozilla has already debuted a new Firefox for Android beta. This new release adds open source custom fonts and HTML5 compatibility optimizations.

The Firefox beta for Android comes with the custom open source fonts Charis and Open Sans. They will replace the default Android fonts for what Mozilla claims is “a visually appealing and clear reading experience.”
