Opera was my main browser. I loved using it until I started getting these weird news pop-ups that wouldn't go away even though I turned off notifications for Opera. I thought that would be the only problem I'd run into; then I hear about the crypto browser. I doubt those at Opera are unaware of the toll that many servers running at once takes, energy-wise, and I can't support a company willing to lay waste to the environment. I'm not going to be using Opera anymore.
