StumbleUpon is a wonderful way to randomly explore some of the best web content, photos and videos on the Internet. It shows websites that you are very likely to enjoy as they are recommend by like minded people..
To use StumbleUpon, you need to install a toolbar that is available only for Internet Explorer and Firefox. There’s no official support for Opera and Apple Safari.
There is however a quick workaround so you can continue to find great websites with StumbleUpon without downloading the toolbar – the trick works on non-supported browsers as well. (see screenshots).

To see how this works, visit the URL stumbleupon.com/demo/#url=http://www.labnol.org/ in any web browser – you will immediately notice a virtual toolbar over the web page with separate buttons for stumbling websites, blogs, photos and videos.
Click the stumble button again to see another site and so on. No installation required and a perfect way to cure boredom.
