Going down the NOSTR rabbit hole, using the Primal client...

It seems to work well on my phone, with me being able to Like and Zap notes, and I have my own @`primal` wallet with a few thousand sats in it. But on the PC, using Firefox (which is what I WAS writing this note on) I can't see my wallet, I can't Like anything (it lets me click the heart but it goes back to being not selected), can't leave comments and can't Zap. What am I doing wrong?
