@spiritwind I'm using the Chromium-based ffmpeg.so to get videos working seamlessly, just not the video previews. I'll try grabbing the github version and trying that to see if it works for my problem.

Just installed 107.0.5045.21 from .deb package after bypassing multiple versions (was using 98.0.4759.39 for a long time) due to video preview crashing pages problems. The problem persists with the newest version available for Linux, running Pop!_OS 22.04 (latest LTS). I have replaced libffmpeg.so (the video codecs) to fix problems with video playback, but can't find a solution for the video preview causing crashing. This happens on news sites that auto-play videos, or on-hover video previews. Reverting back to 98.0.4759.39 fixed the problem.
