This option works fine in the Mail extension, but when I try to use the same option in the Calendar extension, the color I pick in the color box doesn't apply and I get this error:
onClick@moz-extension://28503361-88a0-45c8-a3f3-1864f73ec089/js/popup.js:5447:25
Also just want to say thanks for these extensions! Been using them for years and they have been very handy.
