As I said, use the CustomCSSForFx addon at https://github.com/Aris-t2/Cus... and enable toolkit.legacyUserProfileCustomizations.stylesheets in about:config.
All you have to do then is edit a single configuration file, and in that just comment out/in the options as you like.
Only problem is that when a new version of Firefox lands, this addon needs to be updated too and then you need to do a diff for the configuration file. That's why I use ESR so I don't have to do that too often.
