Same question as I had a few months ago:

The solution given worked fine... until I just upgraded from 68.0.2 to 69.0.3 (and now it no longer works).

Hi n.p.

Firefox no longer loads userChrome.css or userContent.css by default improving start-up performance. Users who wish to customize Firefox by using these files can set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true to restore this ability.

See the Fx 69 release notes.
