I’ve been using the Slash Mark – Fontstyle Checker extension and it’s quickly become one of those tools I don’t know how I lived without. Hover over a word on any webpage, click, and it instantly shows you the font family, size, weight, color — and even gives you a copyable CSS snippet. extpose.com What I really like: No fussing around with dev-tools: click any word, and boom—font-details popped up. You can drag the popup anywhere, keep it pinned while you browse, and switch to dark mode if you’re working late. extpose.com Totally helpful for designers, front-end devs (and even me just curious about what font a site uses).
