James HarrisSo happy to see stylable scrollbars out in Firefox Nightly. If you're running Nightly, you can install Stylus (https://addons.mozilla.org/en-US/firefox/addon/styl-us/) and copy these into a custom style:
.scrollable {
scrollbar-width: thin;
scrollbar-color: #444b5d #282c37;
}
Colors are for the Mastodon default theme. For toot.cafe theme, use #494558 #2a2833.
