<p dir="auto">Mousewheel click for opening a new tab in background doesnt't work for me in Firefox (19.0.2, Win7 64Bit). In Chrome it works fine for me. Seems that is something wrong with bootstrap.js.</p>
<p dir="auto">Example: <a href="http://twitter.github.com/bootstrap/">http://twitter.github.com/bootstrap/</a><br>
Steps to reproduce: Try to click with the mousewheel on a link.</p>
<p dir="auto">Issue: middle mouse click on a link in Firefox, nothing happens.<br>
Expected behavior: middle mouse click on a link, open in new browser tab.<br>
Live example: <a href="http://twitter.github.com/bootstrap/">http://twitter.github.com/bootstrap/</a></p>
<p dir="auto">Tested on Win7/Firefox19 Safemode/Non-Safemode failed. IE9/Chrome25 ok.<br>
Notice it when I upgrade to bootstrap v2.3.1.<br>
Switch back to v2.3 and the middle button works again.</p>
