YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

Chosen solution

An obscure Reddit thread recommended changing these settings in about:config

gfx.direct3d11.reuse-decoder-device-force-enabled: true media.wmf.zero-copy-nv12-textures-force-enabled: true

This appears to work, at least for YouTube
