Ages ago I used "Bigfoot"'s free email forwarding for life. Which turned into a subset of email with limitations, fees, ads, and eventually shutdown. Later I had my own domain, and did the address-per-site thing. Which was an absolute nightmare to undo when I sold the domain (grepping thru the raw self-hosted mbox and logging into and changing my email on hundreds of sites), although it was a great excuse to get going on using a password manager. At this point I could use "plus addressing" at Fastmail (e.g. amazon+me@domain.com), but I find the endeavor pretty pointless. My spam is low, and I never once found it especially valuable to be able to identify or isolate an offending domain. I don't expect that Firefox will go "full Bigfoot" on this one in terms of ads and fees but shutdown is a PITA risk. I would personally only use this kind of stuff for genuine one-offs where anonymity is paramount (read: probably not at all).
