I appreciate that inspector now has options other than rgb and rgba to display colours but.. Default colour unit should have an 'original' option, to display the colour the way it was actually written. Why firefox does has to modify the css, and not show the actual, original css. Sometimes you have to use extra rules, like prefixes, and inspector won't show those. I know, it's only showing the rule that firefox uses, meaning it ignores -webkit and -ms, but if it showed those prefixes, then I'd know places where they're missing.
