The Fingerprints of Abrowser

Hi,

Here I would like to address two issues relating to privacy of our Abrowser:

1. The fingerprints of my Abrowser gave me like this:

User Agent:
Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0

HTTP_ACCEPT Headers :
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 gzip, deflate en-US,en;q=0.5

-- So my question comes: since "LInux" and "X11" mark me unique among other ordinary users around me, could they be modified or spoofed manually? As I see Abrowser may did a good job that it hid the "abrowser" word while Iceweasel show itself in the User Agent.

--Could I modify other fingerprints ?

2. When I turn on my Abrowser, at the first few minutes, I observe the following active connectivities (while I had not opened any webpages yet):

Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port
tcp SYN-SENT 0 1 192.168.1.107:33126 223.73.1.207:http

tcp ESTAB 0 0 192.168.1.107:47046 52.88.81.160:https

So what are these ip addresses?

Thanks a lot for answering!
