Thank you!

There's currently no simple way to import via Facebook, but a workaround should let you do it.

(as a disclaimer, you'll need an unrelated Chrome extension that I didn't build. Hope I can built an official birthdays.app version at some point)

Essentially, you can: 1. Export your Facebook friends to a .ics file using the extension called "Birthday Calendar Exporter for Facebook" from https://chromewebstore.google.com

2. Upload your friends and their birthdays to your Google Calendar

3. Go to https://birthdays.app, login via text code, and click "import via Google Calendar"

Let me know if any thoughts or questions come up :)
