What is "js.revsci.net"? Firefox will hang saying it is waiting on js.revsci.net


When trying to load a page or if I click on a link, Firefox will just hang saying it is waiting on "js.revsci.net" and then won't load the page correctly or won't take me to the link. Is this spyware?

I HAD the same problem too. All I did to fix it was delete the revsci cookie file. Go to: Tools - Options - Privacy - Show Cookies, and then search for the "revsci" folder which contains those cookies. I deleted the whole folder. No more delays! But I went back to the cookies and found that it puts itself back in there but it's been 3 days and the problem hasn't come back. If it does come back, I now know what to do. I'm using Firefox 3.6.8 Hope this helped
