Trident, Gecko, and Webkit host the engines behind Internet Explorer, Mozilla Firefox and Google Chrome, respectively. Users can choose whichever engine they like by default and switch to others when they can not render a default web page properly. And users can also define different render engines for each website, so Avant Browser Options will automatically activate the render engine when browsing these web sites. A browser that uses the internet explorer sub-structure but opens a page better than that. An opportunity to squeeze from the internet explorer. Automatic text completion, rss feature popup blocking and security features.
