Librus Average is a Firefox extension designed to enhance the user experience on the Librus Synergia website by displaying your average grades. Many educational institutions may choose to hide this information, and this tool addresses that gap by providing easy access to your averages. Users can customize how their averages are calculated, allowing for a tailored experience that meets individual needs.

The extension is fully open source, providing transparency and flexibility for users who wish to explore its features further. Additionally, it offers a clutter-free interface, allowing users to hide subjects without grades through a simple options menu. Available on multiple platforms, including the Chrome Web Store and Opera, Librus Average is a versatile tool for students looking to keep track of their academic performance.
