Opera Software has announced the release of new one-click setups that customize the company's Opera browser so that it mimics the look and feel of Internet Explorer, Apple Safari or Mozilla Firefox.

The setups change Opera's skin, toolbars, menus and keyboard shortcuts, and the developer also offers a series of setups that open advanced Web developer capabilities.

You can download the necessary files, which are free, from the Opera Software Web site, where the company also hosts a My Opera Community that features hundreds of user-made modifications to the browser.
