Google Chrome (free web browser)

A web browser to replace Microsoft Internet Explorer, Apple Safari, or Mozilla Firefox. Provides bookmark, password, extension and tab syncing across systems, is very fast and standards compliant, has built-in Flash and PDF readers, silent auto-updates, has lots of new technology and is pushing forward the boundaries of web browsing while staying more secure than the competition. I use this application more than anything else installed on my systems. Based on the open source Chromium.
