Maxthon 5, huh?
Well, based on this thread I decided to download it.
Things haven't worked out quite so well in the hour I've used it.
First it wanted my phone number to send a verification code. That didn't work. Then I was asked for my email address. That eventually worked, though I got a message saying, "Sorry, sever break down. Try again" a few times. Very broken English. Turns out Maxthon is made by a Chinese company.
We shall see how this works.
