Goona Browser 0.6.0.1
Goona Browser is a free, opensource and fully standards-compilant web browser, released under the GNU General Public License 3.
Goona Browser has a Setup Center where you can define how do you want Goona Browser to look and act.
The download manager included isn't a standalone application, but a powerful multi-segmented download manager (comparable with the most known download managers currently available) that runs in a tab inside Goona Browser.
As a small detail, it also integrates with twitter letting you share any page and post tweets directly from the Goona Browser window, without needing to open any other tabs.
Since version 0.6.0.1 Goona Browser has an interface with Windows Aero effects (which will be visible if you are using Windows Vista or Windows 7 with Aero theme enabled), and a more complete First Run Wizard that makes easier for new users to set up Goona Browser the way they like. this First Run Wizard is able to import your favorites from existing browsers.
