firefox-chrome

firefox-chrome is a CSS & styling skill for AI agents, published by adriankarlen in the textfox repository on GitHub. Skillspace rates firefox-chrome D (59/100) and it passed the safety scan; the rating is based on static analysis only.

Ground truth for Firefox's internal chrome UI — the DOM structure (browser.xhtml) and built-in CSS that userChrome themes target. Use when writing or fixing textfox CSS and you need to know a real selector, element ID, attribute, or Firefox's own default styling — instead of guessing. Triggers: "what selector", "what element is X", "did this break", "firefox renamed/removed", "userChrome", "why doesn't this rule apply", "find the real DOM node", any time CSS targets Firefox internals. Always targets the LATEST Firefox release (the only version textfox supports).
