User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3

Firefox create some pairs of localhost connections. 
(as described by  Wan-Teh Chang   2002-03-25)
https://bugzilla.mozilla.org/show_bug.cgi?id=100154#c18
But port numbers take randomly, and it create problems for other software, also running on localhost.  
If that software start after firefox and want to take, for example, localhost:1042, it cannot because firefox already taken it.

Please, add to preferences a port range in which firefox can take the localhost ports. Then every user can configure that ports in own configuration.







Reproducible: Always

Steps to Reproduce:
1.start firefox
2.netstat -ano
3.see localhost:NNNN Established 
Actual Results:  
  TCP    127.0.0.1:1677         127.0.0.1:1678         ESTABLISHED     3232
  TCP    127.0.0.1:1678         127.0.0.1:1677         ESTABLISHED     3232

Expected Results:  
want to configure NNNN range.

FF 4.0b4 using 62417 - 62418 ports... it's more reasonable.
