I think #Sidecar is the best full-fledged #nostr signer/wallet (browser extension) I've used so far! It covers all my needs and has the following features: Multiple accounts Multiple NWC wallets (each account has its own wallet) wallet connection backup Wallet spending budget Signer activity Nostr profiles Relay lists Backup and restore profile, follows and mute lists A Nostr composer If you need a Nostr signer that's a browser extension, I highly recommend Sidecar.
