Hang Firefox 3 on Mac with Firebug

July 4, 2008

This 2-line web page will hang Firefox 3 with Firebug on a Mac:

<body onload="debugger">
<img src="">

(With Firebug scripting enabled)

This completely hangs the Firefox user-interface, so you can’t access your other tabs. The only thing to do is a Force-Quit. I reported the bug but unfortunately I just don’t have the time and energy to learn how to fix it myself. Hoping somebody out there might have some useful insights.
