firefox sidebar scroll very thin (hard to tell you can scroll)

You also need to hover to see you can scroll down - a user was confused on how to see all followed channels. Maybe some hint that you can scroll down to view all / make view all more obvious.

Only way i can think of improving this is by always showing the scrollbar and maybe making it a different color depending on the theme plus thicker? (It seems that on the android app it is thicker and always shown so)

I can work on a PR if you want!

I think this should be closed as #3396 is merged

Thanks!
