It seems the latest Firefox is locked to 60FPS max now? How can I get it do display more?

I'm using Firefox on Arch Linux x86_64. I have a laptop with a 144Hz display. Websites and their animations looked super smooth. However, when I upgraded to the latest version of Firefox, everything seems to be locked to 60FPS max. It's ugly and jittery as hell. If I go to https://testufo.com/ it says "UNSUPPORTED: VSYNC is not available on the Linux platform." I haven't changed my system configuration or graphics settings at all.

Go to about:support and check the "Target Frame Rate" value.

Try downloading another copy of Firefox and run it from the folder. Do not sign into your Firefox account and see if you have the same issue.

That also doesn't work.

EDIT: I tried Firefox Developer edition. TestUFO still says that Vsync isn't supported but It's running at 144FPS now so that seemed to fix my issue (at least, until Mozilla releases an update that will ruin things again).
