If that would be true, the websites would only support Safari and Chrome. But it's not true and websites work just fine on Firefox - so stop peddling this crap to defend lockout of choice.

There are plenty of websites that have degraded performance or functionality in Safari and Firefox. The most obvious being many of Google's products.

I use Firefox extensively with Google products and I don't know what you're actually talking about? Degraded how?

Ah yes, you're right. We should be thanking Apple for restricting user choice...
