I am the extension author. My extension exists since a long time. And recently
I discovered a problem that exists only for some HTML pages ? when they are read from the cache.

In Firefox 2.0, when looking the same page, Firefox completely hangs.
In Firefox 3.0, it is better. It seems to work fine. But when exiting Firefox, the process stay alive. You need to kill it via the Task Manager on Windows.

It happens after opening a channel for getting a HTML page from the cache.

    var ios = Components.classes["@mozilla.org/network/io-service;1"]
                        .getService(Components.interfaces.nsIIOService);
    var channel = ios.newChannel( url, urlCharset, null );
    [...]
    var stream = channel.open();  <- HANGS


Reproducible: Always

Steps to Reproduce:
1. Download the HTML Validator extension. It is available here:
  > http://users.skynet.be/mgueury/mozilla/download.html
2. Restart firefox
3. Go to http://www.dquinn.net/home/404.php
4. Exit firefox
Actual Results:  
-> The process stays in memory

Expected Results:  
-> The process quits

I logged a bug some time ago for Firefox 2.0. This is exactly the same bug but for Firefox 3.0. The result is different, but the cause is the same.

I tested this with latest trunk on Windows XP but couldn't reproduce the problem. When I close the browser the process exits normally.
