Apple does this by sending an imposter user agent from Safari on iPads.
If only that was expanded to iPhones, too. And then send rotating, or randomized user agents.
Google does.
And while Mozilla does too because the vast majority of their funding comes from Google, it’s more pertinent that they don’t have the market share to pull this off. Firefox would just stop working on major websites if they did this.
