!important / @namespace
Is it still necessary to use both !important and @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul) inside userChrome?

I've been on a warpath against using @namespace for nearly four years. Ref. https://www.userchrome.org/adding-style-recipes-userchrome-css.html#namespaces
You need !important in many cases to overcome the sometimes unpredictable way that browsers apply the precedence rules of the CSS cascade: https://developer.mozilla.org/docs/Web/CSS/Cascade
Thanks for that. I have been suspicious of @namespace for some time. I will omit it for the time being.
