@Matjaž-Škabar I have the same issue with firefox 138.0.4 (64-bit) on linus (nixOS) running wayland as window manager.
I don't have an external GPU (laptop with intel graphics), so it might be a webgl thing?

It completly frooze my whole system twice after looking at the weather radar.
I'll try to reproduce with chromium and find some logs from the last crash.
