Arora is a Qt browser that uses webkit (rendering engine used in google chrome and safari) as it’s html engine. It’s small, and fast too.
The current version of the windows build of arora (0.10.0) is not the latest version.
Presenting the windows build of arora 0.10.2 – git build version as of march 24, 2010. I myself have compiled it under Qt 4.6.1
