Canvas allows you to instantly wrap your Firefox browser with any photo or image. Add photos from your computer, or from sites like Flickr and Facebook. Click the “MyPix” button to switch the picture in your browser any time you wish. Clicking “Manage” in the toolbar allows the user to add and remove images, or to modify the look by changing image position, background color and tiling.
