Add Bidi Support is a Firefox extension designed to enhance web accessibility by adding bidirectional text support to websites. This tool modifies the display of text to ensure that both left-to-right (LTR) and right-to-left (RTL) languages appear correctly, improving readability for users who work with various languages. Currently in development, this extension aims to provide guidelines for web developers to integrate bidirectional support into their designs, ultimately making the tool less necessary as web standards evolve.

The add-on is freely available under the GPLv3 license, allowing users to utilize, study, and distribute the software. Importantly, it does not collect any user activity information, ensuring privacy while enhancing web experiences. Users can access the source code on framagit, promoting transparency and community involvement in its ongoing development.
