Yep.

The program is what we cal call a "client" - much safer 
than a server against crackers.

> 3. Most er go ports open @ your computer ?
No, no open ports, no trojans or spyware: the sources are 
available for audit and recompiling if necessary - this is 
one of the advantages of free (libre) software.

> 4. most your connection be changed ?
You have to give access to outgoing HTTP(s) (outgoing TCP 
port 80 and 443), which should be sufficient.
