[Chameleon] request failed: error reading the headers in Firefox Explorer

[Brian May]

I see this problem, too, when using the latest FireFox 2.0.0.8 on 
WindowsXP. I tested with FireFox 2.0.0.6 on WindowsXP and no problem. 
Same behavior tested against two MS4W installations v. 1.5.1 and v. 
2.2.6 using Apache on Windows 2000. IE 6 and 7 on WindowsXP work fine.

The Apache POST request shows a 400 error, i.e. Bad Request

Seems Apache doesn't like the way the latest FireFox is sending the POST 
request.

Any clues as to how to fix? Just wait for a new FireFox?

thx
