What makes Thunderbird observe settings in userChrome.css

For years I have had customised folder colours for new mail in Thunderbird. These are set with a file userChrome.css in a chrome folder in my user profile. I created a new profile to try to sort some bugs and copied the file and folder from the old profile to the new profile but Thunderbird will not observe the rules in the file in the new profile If I swap back to the old profile all is OK again (except for the bugs I am trying to avoid).

Is there setting in Thunderbird (like Experimental) that I might have set in the old profile to get Thunderbird to look at the css file.

Thanks, steve

Chosen solution

Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor for the new profile.

Thanks very much, worked a treat. Would have taken me a long time to find that. My old profile config has a huge amount of stuff from deleted accounts, deleted add-ons, etc.

Where does one do this? We don't have a new profile, but are trying to start using userChrome.css to improve the appearance of 78 on one of the machines here and so far it seems to have no input. But, what is config.editor?

In reply on another thread I found out how to do this, so we'll see if it helps!
