Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 

This happens when FF runs on WIN7, bur not on Vista

Reproducible: Always

Steps to Reproduce:
1. Just do it in WIN7 and it fails
2. Do it on Vista and it works
IE have no problems
Actual Results:  
414 Request-URI Too Long: Buffer overflow detected 

Expected Results:  
Normal response - with updated screen

The WEB server is an Embedded processor and is therefore more critical with the returned size rom INPUT/GET. 

If you need it i can device a special userid/password for your testing

Not security-sensitive. Please provide an HTTP log, which will show the URLs that Firefox is actually requesting: https://developer.mozilla.org/en/HTTP_Logging

The request looks mostly-identical: there is a slight difference in the User-Agent, but the working UA is actually the longer one. The Win7 version has two cookies, which is slightly odd. Could you try clearing cookies on win7 and trying again?

With Cookies cleared on WIN7 it worked.

This is a bug/limitation of the server in question, I think. Glad we could help, though!
