What versions and operating system are you using?

OS: Windows 7 32bit Firefox: 6.0.2 Firebug: 1.8.2 FirePHP Server Library: 0.3.2 FirePHP Extension: 0.6.2

What is the problem? When the FirePHP extension is used in Firefox 6.0.2, it doesn't add the "FirePHP" to the user-agent header.

I've also triple-checked that I've enabled "Modify User-Agent header" setting for FirePHP.

What steps will reproduce the problem? 1. Open Firefox 6.0.2 2. Enable the "Net" tab under Firebug 3. Ensure that the "Modify User Agent header" setting is ON for FirePHP. 4. open any website (e.g. http://www.google.com/) 5. Have a look at the User Agent string in the Request headers.

What is the expected output? What do you see instead?

Expected output is: Mozilla/5.0 (Windows NT 6.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 FirePHP/0.6

Instead I see: Mozilla/5.0 (Windows NT 6.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

Please provide any additional information below.

Downgrading Firefox to 5.0.1 running FirePHP in Firebug 1.8.2 solves the problem.

Try with a fresh Firefox profile using Firefox 6. That usually solves things.

Alright, that did it. Thanks.
