This is a thread where you can share your favourite Google Chrome extensions that you found to be useful. I'll go first. 'iChrome New Tab' is a great extension for customizing your new tab behaviour. Want the weather? Set the weather to show up every time you click a new tab. Insert your bookmarks bar. Pick a background that you like. If you hate your existing new tab setup, you can customize your new tab to look like virtually anything you want in a few clicks.
