Make it Easier to Adjust Frame Rates

[MarjaE]

A lot of common web design practices give me motion sickness.

Animation, more animation, non-scrolling nav elements alongside or in front of scrolling elements, non-scrolling backgrounds behiond them, more animation, everywhere animation...

I know Firefox has options which can help.

prefers-reduced-motion, disabling smooth scrolling, disabling autoscroll, disabling autoplay, disabling blinking cursors, using my own animation-blocking css, using uBlock Origin, etc. can only do so much, especially when many sites use Javascript or obfuscate their css. I can't scroll about:preferences or about:addons, and have to search the one and page down the other.

I've only found one solution which works on all this animation, and all the incomplete scrolling: to reduce layout.frame_rate to 1.

But I have to switch the frame rate back and forth between 1 and 50 or 60, depending where I am and what I'm doing. I can't use a middle value because that would cause a strobe effect.

So I don't know if anyone else would find it helpful, but I'd find it very helpful to be able to toggle layout.frame_rate without going through about:config every time.
