A place to discuss the news and latest developments on the open-source browser Firefox
I don't know what to do. I've tried searching through google and all the answers don't seem to work. When I use Firefox (this is librewolf but it's the same on Firefox), games like Tetr.io or Friday Night Funkin lag real bad but they're buttery smooth on Chrome or Chromium. I have an iGPU and a "Cedar" AMD GPU according to lspci. Someone please help me, I don't wanna use Chromium just to get good performance. Please tell me if I need to provide more information.
I don't understand why this stuff isn't enabled by default on Linux, it's such a detriment to new users when super basic features don't work out of the box.
Firefox Hardware video acceleration
If hardware video acceleration is blocked with error code FEATURE_HARDWARE_VIDEO_DECODING_DISABLE or FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED in about:support, you can override it with media.hardware-video-decoding.force-enabled=true. See [10] for more information. Alternatively, you can install firefox-vaapiAUR.
Also make sure that in about:support Compositing in the Features table under Graphics is set to WebRender if it is not than set gfx.webrender.all in about:config to true.
I had the same issue but I have a NVIDIA gpu. but I just had to install libva-nvidia-driver and edit Kernel parameters and Environment Variables . I got this to work with both Firefox and Librewolf but only some video codecs.
note i have 1080ti so i don't have hardware acceleration for av1. also the only time a problem when I turn off hardware decdoing on firefox is when I watch a HEVC stream on twitch for some reason i get drop frames every second.

Did all that but it's still the same. I really don't know what's the root cause of this.
I sure you have but have you tried checking the out put of vainfo Arch wiki since Firefox only supports Hardware acceleration with VA-API.

This is what I got, I still dunno what it means. which gen is your igpu? Older intel igpus need libva-intel-driver pkg installed (on Arch, not sure whats the Fedora equivalent) and the env variable LIBVA_DRIVER_NAME set to i965.
See also https://wiki.archlinux.org/title/Hardware_video_acceleration#VA-API_drivers.
According to fastfetch it's a "Intel Xeon E3-1200 v2/3rd gen core processor"
When I tried to run "LIBVA_DRIVER_NAME=i965 firefox" it spat out "restorecon: SELinux: Could not get canonical path for /home/[myusername]/.mozilla/firefox//gmp-widevinecdm/ restorecon: No such file or directory."
What’s your distro?
How is Firefox installed? Distro package or flatpak?
Fedora, but I had the same problem on Arch.
Currently I have it installed through Flatpak but I have the same problem with distro package.
Is media.ffmpeg.enabled set to true in about:config?
It’s also true that graphics performance of Firefox is just not as good as Chromium, even with hardware acceleration.
I have the same exact set up on my Thinkpad x240 and it's running smooth on Firefox so I dunno... I'm ripping my hair out over this tbh.
Yes.
