Sigh, still no private payments through Monero support from a privacy focused browser with crypto features.

I can't vouch for the quality of the project.

Monero has slow confirmation times. It requires a 0-conf to be able to do micropayments. Most wallets also require a full 10 confirmations before you can use your balance.

There isn't Lightning on Monero, how would you do micropayments?
