Maxthon is a tabbed browser based on the Internet Explorer rendering engine. It supports mouse gestures, ad-blocking, skinning and a built-in RSS reader sidebar. It also has privacy protection features. For example, you can erase browsing history, cookies, cache etc. with a single click, or configure the browser to clear them automatically when it closes. Download the installer and install to the default folder. Then copy all files (except MaxthonUINST.exe) to a folder of your choice. Finally, uninstall the program. Launch Maxthon.exe.Note: I did not select "AI RoboForm Plugin" and the various sidebars during testing, so I am not sure if any of those external components/plugins are portable.
