Google Chrome already sports a number of security-minded features, from Incognito mode to a software sandbox which makes exploiting the browser a Herculean task. Now, Google has announced additional protection for Chromium and Chrome users.

Built upon the Safe Browsing API, the new feature introduces protection against malicious downloads. If a download link appears in the Safe Browsing blacklist, Chrome and Chromium will warn users against downloading -- a save button is still presented, of course, in case you're convinced a file is perfectly safe to download.

We'd like to see something a bit more eye-catching than the red warning icon -- like perhaps painting the entire bar red. Many of the people a feature like this aims to protect probably won't notice the icon or change in wording as they'll be focused on clicking the save button.

Google is initially making download protection available to Chrome dev channel users, and you'll likely see it in Canary and Chromium snapshot builds as well. After thorough testing, beta and stable users will be next in line.

The first is a full-featured proxy API, which will, for example, allow users to set different proxy servers for normal browsing and Incognito mode. Proxy auto-config scripts are also supported by the API.

The second -- Web Navigation Extension -- is a bit more expansive. This API will allow devs to build everything from more powerful safe browsing extensions -- like Traffic Light -- to data analysis and reporting extensions.

Both APIs are currently experimental, so you'll need to enable them on the about:flags page to try out any relevant extensions. Apart from a proxy example built by Google and shipped with the Chromium source, we're not aware of any examples just yet, however. We'll let you know when we spot any slick, new extensions which do surface.
