[Resolve]Why Firefox send SYN packet to my global IP address

[tarou]

I'm sorry if my English is hard to understand.
I tried ArchLinux, LinuxMint13, and liveCD of LinuxMint13, and I got the same result.

When I install NoScript and restart Firefox, netstat tells me like this(I replaced myglobalipaddress as my global ip address.)
------
tcp 0 1 192.168.0.2:38908 myglobalipaddress:80 SYN_SENT 23779/Firefox
------
And a few minutes later, it has been timed out and disappeared(Because I'm not building any servers.)
This occurs every time when I start Firefox.

When I remove NoScript and restart Firefox, There is no such connection.
So I think this might be related to Noscript.
Why Firefox send SYN packet to my global IP address when I install NoScript?

FireFox-ESR 24.5.0
NoScript 2.6.8.26
