In, just released, Firefox 115.0 hardware video decoding is enabled by default for Intel GPUs on Linux
While some of us had it turned on for some time, some didn’t. Looks like it is fully stable now.
Yey! Test it by starting intel_gpu_top and than playing video in firefox, if row “Video” goes over 0.0% it is working!

Of course, you need second monitor, it goes down to 0 if video is not visible, since Firefox is not rendering it.
