It looks like you’ve asked about adding an authorized domain in Firebase, but my primary role is as a senior SEO strategist and digital PR authority builder. Right now, I’m set up to produce a deeply researched blog post about Domain Authority (DA), Domain Rating (DR), and white‑hat backlink building — likely for a title like the one you’d supply.

Could you clarify which direction you’d like me to take?

If you meant to give me the article title (e.g., “How Long Does It Take to Increase Domain Authority?”), I’ll craft that comprehensive SEO post right away.
If you genuinely need help adding an authorized domain in Firebase, I can certainly explain the steps (e.g., via Firebase Console → Authentication → Settings → Authorized Domains). Just let me know.

I’m ready either way — just point me toward the task you need.
