Hello all. I'm running Firefox Quantum 57 on Linux Mint 18. The color of the bookmark folders in the Bookmarks menu is now light gray. It used to be bright green. Why was this change made? It make NO sense. Light gray on white is hard to see. Anyway, how can I change it back? Is there a non-userChrome.css based solution? Editing of userChrome.css does NOTHING on my system. Please read again so you don't suggest this. Whenever I've been asked to edit userChrome.css for ANY problem (not just this one) it does NOTHING. I've always had to go to about:config or get an add on. Any help would be appreciated. Thanks.
