I can't get firefox testing to be stable on windows
 
I launch firefox quite a few times (perhaps more than 10-15) during my
 test session, and it hangs at some random point, not the first, or
 last launch. I wonder if it is related to the no. of instances I
 launch (it probably uses 7055 port every time?)
 
I see this on:
 
Firefox v: 3.6.10, 4.0beta 7
 OS : Winxp, Win 7 64-bit
 Kaspersky antivirus 6.0 (Tried turning this off)
 
My test code looks similar to
 
b = new FirefoxBinary(new File('location/to/firefox'));
 Webdriver d = new FirefoxDriver(b, null); // I already tried the
 simple version new FirefoxDriver() as well, no help
 //do stuff
 d.quit()
 
I keep running into a serious hang, very often, though not every time.
 I am launching firefox quite a few times, but sometimes I get a hang
 even the first time around. This means I am not able to get firefox
 testing in my automated builds at all. If the server is being launched
 each time on port 7055, could that be the source of my problems? I do
 see about 5 or 6 netstat entries after launching one firefox window
 (using netstat -ao | grep 7055)
 
I see the usual error message:
 
org.openqa.selenium.firefox.NotConnectedException: Unable to connect
 to host 127.0.0.1 on port 7055 after 45000 ms

Here is some more information I gathered from a winxp, firefox4.0beta
 7, webdriver-2.0a5 setup:
 (Using 2.0a7 does not fix this)
 The error console gives me the following errors, when firefox is hung:

I can provide zip of the temporary profile directory if needed
