Ever have one of those days? I just wasted 3 hours tracking this down.
I had this document open and the JS Tabbed panels would not fire in any browser. WAMP is my local testing server.

Good grief! It turns out jQuery must load first otherwise Bootstrap doesn't load.

If you missed the comment that said "<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->" in the basic template code example on http://getbootstrap.com/getting-started/#template then the first line of bootstrap.js should of tipped you off:
if("undefined"==typeof jQuery)throw new Error("Bootstrap's JavaScript requires jQuery");
