Based on IE5, Phoenix Pro can run all of today's Internet technologies, including Java, JavaScript, HTML5.0, SHTML, DHTML, XML, ActiveX and more! This Internet suite includes single-pane browsing, multi-pane browsing [five browsers at once, via tabbed interface], System Tools, e-mail, file management, FTP support, a download calculator, helpful tour, and stunningly easy interface, none of which interferes with your Windows settings or registry. To add to all that, Phoenix Pro does not require Internet Explorer to be installed!
