Smooooth as silk.

how can i revert back to defaults?!

Thanks for developing this. I am a laptop Linux user and I have a 4k external monitor, so the output is rendered by Nvidia GPU. When I used Firefox with smooth scrolling (which is set by default), there were always lags whenever I scrolled in Google. But after disabling it and using this extension to tune scrolling, everything has been perfect!

does not work!

It stopped working for me after a Firefox update but I did get it to work again after fiddling around toggling settings in about:config and uninstalling/reinstalling the extension a few times. Not fun thanks to the FF update but at least it is working again.

I'm not sure of exactly what did it but if anyone else is having issues, try uninstalling YASS, enable FF's default smooth scroll, reset the general.smoothScroll.mouseWheel.migrationPercent setting to 100, and toggle mousewheel.enable_pixel_scrolling off then back on again. Leave both pixel scrolling and FF's smooth scroll enabled, restart FF, and reinstall YASS. Might work but YMMV

Some folks are complaining that this add-on no longer works. I installed it and had it working as I wanted it within 5 minutes. Maybe I'm odd. I'm pleased with this add-on and if I had found it sooner I would of saved me a couple of hours messing around in about:config trying to make my scrolling smoother.

Unfortunately, the add-on no longer works with the update to Firefox 84.
I ask for an update. Many Thanks.

Edit:
Thanks to User 6859214, his Workaround works for me. Now it scroll smooth again.

I can confirm that after last FF update this extension isn't working at this moment.

had it for many years. however, no longer has any affect. doesn't work at all. Is it possible its due to that I also run Gesturefy ?? i dunno. but the addon should self actualize if its no longer having an affect, or why. compatability issues?

FF's built-in smooth-scrolling features no longer seem to work, so I've returned to this extension, which had gotten unreliable—and now it works! Yay!

The addon is very customizable and works as advertised, but there's one big problem. On websites with lots of autoplay videos, like Reddit for instance, scrolling through will become very laggy and skip around repeatedly, losing all smoothness. This doesn't happen with Firefox's native smooth scrolling or autoscrolling feature. I'm on Linux by the way. Not sure if that's relevant.
