How can I add a custom toolbar button to Internet Explorer?

Question

How can I add a simple toolbar button to IE that gets the current url and redirect to another url?

Answer 1

• Powering up with Internet Explorer Extensibility
• Adding Toolbar Buttons at MSDN

Answer 2

If you don't want to get deep into all the IE extension stuff, you could go with a bookmarklet and just use javascript to get the same behaviour you are looking for:

javascript:if(location.href="http://www.google.com"){ location.href="http://www.yahoo.com"}

This also has the advantage working on many different browsers.
