Oops, this is the version with corrected grammar, sorry...

I just need to know how to enable the hardware decoder on bilibili.com when watching videos using Firefox on Android.

I have tried to solve this problem using AI, and I followed the steps provided by DeepSeek. I made sure my device supports HEVC and AVC hardware decoding (Snapdragon 870). I also tried switching my User-Agent to Safari 18, macOS X, but it didn’t help. However, when I followed the same steps on Edge Canary, it worked. This has been frustrating for me. Every time I switch the quality options to 8K, the video playback becomes very choppy. According to `edge://gpu`, I’m very sure that 8K video hardware decoding is available on my device. Thank you, whether you can or cannot solve my problem.

(Sorry about my poor English; I’m still learning it in school.)

Try to open about:support and go to the Media section. There should be a list of supported codecs. I'm not sure that we support hardware accelerated HEVC on Android right now.

This is a screenshot, hope it helps.I've also attached a screenshot from edge://gpu in edge.

It could also be an issue with the video platform. I just tried using the PC adb command `adb shell dumpsys gfxinfo` on YouTube and observed that the hardware decoder is indeed working. Thank you for your trouble, and I appreciate your help.
