Comodo Dragon is a free browser based on Google Chrome, with some additional enhancements to increase security and protect your privacy.
If you visit a secure site that has a domain-only certificate, for instance, then most browsers will accept it without question. Comodo Dragon, however, will point out that this may not be reliable. Domain-only certificates are available to anyone, at low cost and with no verification, so shouldn't be regarded as conclusive proof of identity.
Comodo Dragon is equally cautious with your personal information. The company point out: "Other Chromium Project-based browsers refer software errors to remote servers. When it finds software errors, Comodo Dragon responds with error messages found on the PC browser, keeping information about the user's Internet travels private."
You also get a shiny new set of browser icons, which give Comodo Dragon an appealing look. And the browser's memory footprint is a little reduced, because Comodo doesn't include some features that are standard in the current version of Chrome, like bookmark sync and extensions support.
A good looking Chrome variant, which may be worth a try if you like the browser and don't mind the lack of support for extensions
