Hello,

I'd like to make the scroll bar thinner and don't know how, all the advice I have found online either doesn't work or isn't clear enough for me to follow.

The scroll bar is ok on a new tab but becomes wider on websites and sometimes creates a horizontal scroll bar.

Thanks.

Hi tommagu

Websites can create their own scroll bars and override the scroll bar width and color via CSS rules.

Firefox 64-78 had prefs to prevent a website from overriding your default scrollbars, but this is no longer possible in Firefox 79 and newer.
You would have to use code in userContent.css to set scrollbar color and width.
