Here's a tip for those who, like me, still juggling between Mx5 and Maxthon 4.4.8.2000 Cloud.   It is possible to have access to new Mx5 features from Maxthon Cloud 4.4.x. To do this, simply go to this site:   https://www.uu.me/   and connect with your Maxthon Passport identifiers. You will find the left Mx5 tab.
