How do you maintain feature parity across Chrome, Firefox, and Edge?

Thanks for noticing — this is genuinely one of the hardest parts of building a browser extension! 🙏

Here's a peek behind the curtain:

• 🛠️ Built with WXT framework — a modern extension framework that handles a lot of cross-browser plumbing

• ⚛️ React 19 + TypeScript — single codebase for all UI surfaces, strongly typed to catch platform-edge cases early

• 🧪 932 automated tests — our test suite runs across the extension to catch regressions before they hit any store

• 📦 Manifest V3 compliant — built natively for MV3 from the start, not ported from MV2

• 🔄 One codebase, three builds — platform-specific quirks are handled at the build layer, not in feature code

The goal was always: you install it on your browser of choice, and it just works the same way. No "Firefox version is behind" or "Edge is missing features" situations.

"Write once, run everywhere — except this time, we actually meant it." 😅
