Avant Browser is a freeware web browser from a Chinese programmer named Anderson Che, which unites the Trident layout engine built into Windows (see Internet Explorer shell) with an interface intended to be more feature-rich, flexible and ergonomic than Microsoft's Internet Explorer (IE). It runs on Windows 2000 and above, including Windows 8 and Windows 8.1. Internet Explorer versions 6 through 9 are supported.
Version 2012 (released October 2011) was separated in two editions: Ultimate edition, which added the Gecko layout engine (used by Mozilla Firefox), allowing the user choose between both layout engines, and Lite edition which contains only the Trident layout engine.
As of November 2008, total downloads surpassed 22.5 million.
Avant Browser is currently available in 41 languages.
History and development
||This article may require cleanup to meet Wikipedia's quality standards. (January 2009)|
Avant Browser was largely inspired by Opera, the first major browser to have a multiple document interface. The developer's objective was to wrap a comparable interface around the layout engine used by Internet Explorer, thereby achieving Opera-like ergonomics without suffering the frequent problems that browser had rendering pages tested only in Internet Explorer. In fact, it was initially released under the name "IEopera", though this was soon changed due to the obvious trademark issues.
The Avant Browser's default search engine is a version of the Yahoo! search engine renamed Avantfind and is given a custom look. Other search engines are available via the address bar' "Quick Search" facility, and instructions on how to change the default to an engine of the user's choice have been posted by the very active Avant Browser user community.
The community has also created other tools and extensions for Avant, including registry files which allow it to use the Information Bar and other security enhancements of Windows XP SP2.
Alongside Avant, the developer used to have a sister project known as Orca Browser, an Avant-like shell of Mozilla's Gecko layout engine as used in Firefox 3 and it has similar approaches to Flock.  Orca Browser project is now discontinued. Gecko layout engine was included in Avant Browser version 2012 Ultimate edition, alongside the traditional Trident layout engine.
Avant Browser 11
Avant Browser 11 (build 130 released on January 26, 2011), introduces more new features than any previous version. These include support for many toolbars that are compatible with Internet Explorer, a facility for users to create their own scripted toolbar buttons, and a password and form-filling wizard. The overall trend though seems to be a gradual movement away from Avant's Internet Explorer roots.
More radical is the addition of a native bookmark system in place of sharing Internet Explorer's Favorites. These bookmarks may be stored online - as can feeds, autofills, and browser settings.  This allows the user to synchronize any number of Avant installations on different computers. Avant can still share Internet Explorer's Favorites. This option was reintroduced by the developer after some users lamented its loss.
Another innovation is that Avant may now be run from a USB flash drive (or other portable storage device such as an MP3 player) without needing to be installed. In conjunction with Avant's session saving facility, this allows the user to halt a browsing session on one PC, move to another and resume viewing the same web pages.
Avant Browser 2012
Avant Browser 2012 Ultimate edition (build 3 released on October 25, 2011) added the Gecko layout engine (the rendering engine used by Mozilla Firefox), and the most recent release (build 168 released on April 6, 2012) also included the WebKit layout engine (the rendering engine used by Safari), making Avant Browser a three-engine browser. Layout engine is selectable by the user.
