I have no idea what the other reviewers are talking about. Before blaming the app, perhaps you might want to take a look at your firefox's about:support settings and make sure that your settings/OS/drivers aren't blocklisting the h264 functionality. This project has made my old Sandy Bridge i5-2435M, Ivy Bridge i5-3320M and Haswell i7-4960HQ fully USABLE in the year of our lord 2025.

Of course certain iGPUs aren't powerful enough even with AVC decode (thinking about my first gen Arrandale i7-640M) on 1080p, but hell, this thing just works! Thank you for continuing this project Alex.
