Description

I'm not sure if this is Firefox's fault or the extensions fault, but I thought I'd post it here just incase someone else has choppy scrolling and can't figure out why.

To Reproduce
Ensure smooth scrolling is on in Vimium-FF and firefox preferences
Go to about:config and set "privacy.resistFingerprinting" to true
Scroll using vimium keybinds

Browser and Vimium version
Firefox Version: 79.0
Os: Arch
Vimium-FF Version: 1.66

Research direction

Start by reproducing the reported behavior in Firefox 79 with smooth scrolling enabled in Vimium-FF and Firefox, then set privacy.resistFingerprinting to true in about:config and use the Vimium keybinds. Determine whether the choppy scrolling originates in Vimium-FF or Firefox, and document the result or a confirmed fix.
