It works on FF135.0.1 (aarch64) for me. Ad blocker?

Tried without adblocker and turned off pihole. I did get it work on Zen Browser (FF engine). So my FF might have gotten borked. Console is giving me:

Failed to create WebGL context: WebGL creation failed: * tryANGLE (FEATURE_FAILURE_EGL_NO_CONFIG) * Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

Glad its workin for others!

Worked for me (FF 135.0.1 on Ubuntu)
