pc specs: https://pastebin.com/vVYLjhDR firefox version: 75.0 (64-bit) system and firefox are up to date. sketchfab.com became unusable. webgl window has low fps, as if the hardware acceleration was turned off. i've tried turning it off and on with restarting firefox after each action. doesn't help. im not sure if it became an issue after last update, bc last time i've visited sketchfab was a while ago. it is working fine in chrome and opera
