Honest question: Can you tell me how to increase the scrollbar size of Firefox browser on a Pop!_OS operating system?
edit: https://old.reddit.com/r/FirefoxCSS/comments/15kk98z/how_can... looks promising
I changed the setting for widget.non-native-theme.scrollbar.size.override from 1 to 50 and it increased size.
The initial value of 1 was confusing me because I kept thinking it is Boolean 1.
Posting a solution here in case someone else finds it useful.
about:config is invaluable, but better documentation on the options would really be nice.
