Gmail and Firebug.

[kgun]

What has FireBug to do with Gmail? Today when I logged into my Gmail account I get the following message in red:

"Firebug is known to make Gmail slow unless it is configured correctly. Fix this. Hide".

So Gmail finds out that I have FireBug installed on FF?

Anybody know more about FireBug and Gmail in addition to the message

"Windows or Linux Users
To disable Firebug:

1. Click the green or red icon in the bottom right corner of the browser window to open Firebug.
2. Click the bug icon in the top left corner of Firebug and select 'Disable Firebug for mail.google.com.'"

I get when I click "Fix this".

Only reason, more code on FF?
