I went with SimpleLogin since I’m working on shifting my Gmail over to Proton, and the integration was a perk. I did go ahead and upgrade to the Proton Premium to get more email addresses, and I want to try out the custom domains.
Firefox Relay was my second choice since I already have Mozilla account. Mozilla killing services in the past, Lockwise and Persona 🤨, didn’t help it’s cause.
Yes, MZLA is different then Mozilla Corp. It’s still under the Mozilla Foundation, but separate from Mozilla Corp.
