The scrollbar in Firefox disappears when the pointer isn’t moving. For example, the top right of this site looks like this.
If I touch the touchpad, it appears and looks like this. It’s very small.
Thanks to this note by @mgorny@treehouse.systems I learned how to make it better. Go to about:config
(and agree to the danger) then set widget.gtk.overlay-scrollbars.enabled
to false and widget.non-native-theme.scrollbar.size.override
to 24 or so. The scrollbar becomes permanent and clearly visible. I like this for a several reasons, a main one being that it’s always obvious how long a page is and where I am in it.
That’s far more technical than it should be to tweak this, but Firefox has bigger problems to fix (such as not getting bogged down in AI nonsense).
