have tried them all as well, apart from Rockmelt, and versio 3.5.2.600 of Maxthon is perfect.

Follow the zillion pieces of advice previously posted and forget about which browser you use. Well, don't use the one you loaded up in 1995.
iron ware is a very good browser

If you don't like Maxthon Cloud, then please try Maxthon 3.
