In the past, Internet Explorer has received a lot of bad press for lack of updates, security issues, poor CSS support and more. However, since the release of Internet Explorer 9, we now have an ultra-fast modern web browser that offers an up-to-date UI, support for the latest HTML 5 and much more.
When you install Internet Explorer 9 on your system, the installed HTML web core is built in to Windows (and this element is very hard to remove), there have been a number of attempts to create a replacement for Internet Explorer that take this core HTML engine and add additional features to produce a even better web browser.
Maxthon is one of the more popular Internet Explorer replacement browsers and is constantly updated.
The latest version Maxthon 4 contains a number of improvements and fixes. There are tons of other minor updates, too.
