Way to disable or retheme scrollbars?
The scrollbars in firefox don't look great on dark themed websites, which I strive to do for most websites I visit, additionally the scrollbar popping around according to where your mouse is is incredibly jarring. I understand that the new web extensions don't provide a way to do this anymore (there were numerous addons pre-57). The only solution right now is to change the size of the scrollbars in windows with a registry tweak, or stretch the scrollbar off the screen with a userChrome.css tweak. Neither of those are very good options. If WebExtensions aren't going to have the ability to make this change, I know a lot of us would appreciate it being an option in preferences.

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for what you want.
There is not an addon that suits my needs, and from what I understand regarding the permissions of WebExtensions, there never will be, unless there are changes made to their ability to change user chrome elements, or an option is added directly to a later version of FF.
