|Google Chrome for Linux (Beta)
At Google, most engineers use Linux machines, so we certainly heard loud and clear how much they wanted Google Chrome for Linux. Just like Google Chrome or Windows and Mac, we focused on speed, stability and security, but we also wanted a high-performance browser that integrated well with the Linux ecosystem. This includes tight integration with native GTK themes, updates that are managed by the standard system package manager, and many other features that fit in natively with the operating system where possible.
