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.

Per app. Every connected site has its own daily and per-payment budget. This is designed to prevent runaway apps from doing exactly what you mentioned.
