StumbleUpon is one of the most used web 2.0 social networks on the Internet today. It has become so famous because of its innovative technology which allows StumbleUpon users to discover new websites and rate/review each website according to one’s taste and liking.

Originally, the StumbleUpon toolbar came out as a Firefox extension and later it was developed for Internet Explorer too. Opera and Safari users can be considered unlucky in this case as they cannot enjoy the StumbleUpon features because of the toolbar not being supported by these browsers.

There is however a workaround, discovered by Amit from Digital Inspiration, which allows users of Opera and Safari to use a web-based version of the StumbleUpon toolbar.

The web-based toolbar can be accessed through the url:

http://www.stumbleupon.com/demo/#url=http://www.sizlopedia.com

where, url=http://www.sizlopedia.com is a general parameter used to access any site with the web-based StumbleUpon toolbar.

It works great for non-supported browsers like Opera/Safari and also works for Internet Explorer/Firefox as you might fall in a situation where you don’t have the StumbleUpon toolbar but you can still use all its features using the web-based toolbar e.g. at school or at work.
