I'd need to change the background color of the message list/inbox panel. I tried changing in userChrome.css but it doesn't work, while in the previous TB version it used to work. All the colors of the new UI are fine, except for the black inbox background that is a bit heavy for my eyes... if possible I'd like to make it a bit less dark. Hope you can help me. Best, Gio

Ciao, purtroppo la soluzione che hai provato è l'unica possibile. Solo che i codici di userChrome.css vanno aggiornati spesso e le relativa modifiche sono comunque non supportate -> https://support.mozilla.org/it/kb/userChromecss-userChromejs-userContentcss-non-supportati
