I just installed Little Snitch on my Mac. When I start up Firefox it now popups with the above warning.

I can't seem to find any information regarding sype-transport or port 9911, beyond that it is used for SypeCom transport protocol.

Anybody can help enlighten me?

Could be a firefox addon. Try disabling them all then re-enabling till it appears again. – MrStatic Dec 20 '10 at 0:08

@mrstatic - hmm i doubt it, i just have adblock plus, web developer and firebug.... i have many more including these installed on other computers and don't see this behaviour.... – w-- Dec 20 '10 at 7:15
So, where did you download your copy of Firefox? – Arjan Dec 20 '10 at 7:35 appeared in the download for Firefox 3.6.13.I DID NOT run the file!Instead, My security software scanned the file and tagged it a "ZOMBIE": a file that terminates itself so as not to alarm anti-virus programs. It can, under certain conditions on your computer, launch malicious code from a remote hacker. When I tried to download Firefox 3.6.13 again, Mozilla's name as publisher was on the download AS IT SHOULD BE! How got there is a question for Mozilla. You may well have a malware infection.

It appears it is/was/could have been a mirror site for Mozilla?

For instance, this page shows & below various mirrors. (It does not show the particular port.)

I picked one of the mirrors, "".

Going here,, I find neither "stonekitty" nor "saudi".

Though viewing the source of the page, I do find, "href="", so you would expect that to be legit?

Perhaps stonekitty was at one time a mirror?

In any case, what I surmise above proves nothing.

Do you still have the downloaded file? If so, you can easily verify its validity,

(And in any case, 3.6.13 is dated & you should update to 3.6.17.)

I just ran into this too. Very weird. Stonekitty is listed at that mirror site though as a secondary mirror. Not that I trust them with my browser. – mlissner Sep 29 '11 at 20:35
