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.
