Chrome kills Firefox by extension(s)

Google Chrome is not only overall better than Firefox, it now supports extensions (yes, including for blocking ads) and in a whole new and better way. Extensions are basically a web page, run as separate processes, and can be installed, uninstalled, enabled and disabled without restarting Chrome, they can also be killed from Chrome's task manager. What this means for you, Google and the extension developer, is extensions are instantly available after submission unless they use native code or access the file system. Google still retains a kill-switch for any extension that is found to be malicious, which as far as I'm concerned is a good thing.
So basically Google not only perfected a browser for Windows, Mac and Linux/X/GNU, but they also perfected extensions. I only wish I had Chrome on my iPhone.
