Page Eraser is a Chrome extension that lets you erase elements on a page. You can use it to remove sidebars, distracting content and even Flash banner ads, all the while maintaining the layout of the page. Simply click the button (or press Ctrl Shift E) to enable this feature, and click the element you want to erase. If you want to get the content back, just refresh your browser.
I recently installed SpoofStick for Internet Explorer and I am very impressed
