## Description

Not yet, AV1 is a minimalist Firefox extension designed to disable the AV1 video codec on YouTube and other websites. By forcing the use of alternative codecs like H.264, it aims to improve playback compatibility and performance, especially on devices or setups where AV1 may cause issues.

Ported from the original h264ify extension by erkserkserks, this version by omsku61 offers a streamlined experience without configuration options, focusing solely on disabling AV1 for smoother browsing. Its extremely lightweight nature ensures minimal resource overhead while enhancing video playback reliability on supported sites.
