I have problem with Firefox on Ubuntu. When I scroll on facebook or youtube it doesn't scroll smoothly like it used to on Windows. It's hard to explain but main point is when I scroll down/up it doesnt go smoothly and it's obvious.
Firefox 46 brought GTK3 integration and true "pixel-perfect" scrolling for touchpads.
To enable it, you must set the
MOZ_USE_XINPUT2=1 environment variable.
There are a number of ways to do this, one of them would be to add it to
/etc/environment and then
reboot the machine:
echo MOZ_USE_XINPUT2=1 | sudo tee -a /etc/environment
First of all, this is basic. Unplug your mouse, and re-plug it back in, into a different USB port on your computer. This may just be a loose connection. If that doesn't solve it, keep reading.
The problem could be a certain number of things, but I've narrowed it down to 2 possibilities.
Your mouse scroll wheel is having problems communicating correctly with Mozilla Firefox.
Mozilla Firefox is having other problems, like not finding drivers for your mouse, or simply not connecting to it sometimes.
What I'd like you to do is download another web browser such as Google Chrome, and tell me if the scroll still isn't working. If so, it's a problem with your mouse/mouse drivers. If it does work on another browser, It's a problem with Mozilla. To fix the mouse drivers, just look up ('Mouse Brand Here') Mouse Drivers and download & install them. If it's a problem with Mozilla, just uninstall Mozilla, and reinstall it. If it still doesn't work, leave a comment.
I installed Ubuntu LTS 20.04 and Firefox scrolling wasn't as smooth as in other apps.
I followed advice from this link : in
layers.acceleration.force-enabled to true
