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.

By building error reports into your app, your users can send detailed bug reports with just two clicks.

Here’s a self-destructing MJT app with error reporting.

Is there any interest in having this included in the MJT library? It could be My demo shows how it could be added to the template compiler and the the MQL task runner. (Updated: 21 Aug)
