Between FLoC and AMP, Google's attempts to destroy the web have surpassed even IE levels of toxicity. It's good to see the consumer focused forks of Chromium take a stand here.
Do you honestly see any signs of Firefox's situation getting better and not continuing its free fall?
Market share has nothing to do with whether something is an option.
(But also, what Mozilla has been doing to Firefox last few years if both a travesty and a good thing.)
In terms of what it does well, it’s far better than Chrome. Fencing alone makes it better for almost everyone.
