Strange message in terminal when visiting a website I have my terminal open most of the time. Today while I was searching for a software, search results took me to http://download.cnet.com. I didn't like the software, closed the page and carried on.
When I brought may terminal back up (it was open the whole time on the background) I had a strange message on the prompt saying
No permission to use the keyboard API for http://download.cnet.com

What is this and how the heck it has gained handle to may terminal and should I be worried?
P.S.
I visited another url from that domain and the same happened.
I'm running firefox on OS X 10.6.8
I launched firefox via terminal.
You are getting that message because you launched Firefox from the command line.

I assume that you used &amp; to put Firefox into the background but that doesn't redirect the output so any error will get written to your terminal session. To stop that appearing you need to add 2&gt; /dev/null before the &amp;.

As for what the error means I assume that website has run some Javascript that hit Firefox's security system and bounced.
