Scrollbars in Firefox
I wish permanent scrollbars, because in black mode i don't see the bars, bars to thin and Video/Stream overlay the scroll bar in not fullscreen.
I agree, you should never replace the system scrollbars. They do not behave as users expect for the platform and to be frank the ones Twitch uses are awful - they're far too narrow and autohide.
using a usb mouse might help the issue. It seems laptop users talk about this a lot.
Scroll bars that disappear or lose functionality when you are not already scrolling defeat the point. The scroll bar is so small that it is literally impossible for me to click on. It does not even reappear when I mouse over where it should be.
The scroll bar is an accessibility feature, and making it "sleaker", or more "discreet" literally lowers the accessibility of Twitch.
