Quick PSA : yes, #Mozilla has been disappointing, but so far, they’re the only organization preventing Google to have a full control over web standards. Blink/WebKit-based browsers (Chromium, Vivaldi…) do NOT help at all in that regard.

So please use #Firefox or a #Gecko-based alternative ( #ZenBrowser, #LibreWolf…). Ride the nightly release train and report bugs if you can. #Servo is getting ready, but for the next ~5 years, Gecko is our only suitable option.
