The Firefox codebase: CSS Guidelines
99% theme 70% theme 70% content 99% content font-*, color, *-color, border-*, -moz-appearance [1] line-height, padding, margin cursor, width, max-width, top, bottom [2], etc overflow, direction, display, *-align, align-*, *-box-*, flex-*, order if some css is layout or functionality related, then it is likely content css.
...ride the content values (which is probably what you want), and you're going to want them both after the global values, so your imports will look like this: <?xml-stylesheet href="chrome://global/skin/global.css" type="text/css"?> <?xml-stylesheet href="chrome://browser/content/path/module.css" type="text/css"?> <?xml-stylesheet href="chrome://browser/skin/path/module.css" type="text/css"?> [1] -moz-appearance is tricky.
... generally, when specifying -moz-appearance: foo; you're giving hints as to how something should act, however -moz-appearance: none; is probably saying 'ignore browser preconceptions - i want a blank sheet', so that's more visual.
... however -moz-appearance values aren't implemented and don't behave consistently across platforms, so idealism aside -moz-appearance should always be in theme css.
