690999 - Connecting to myprofile.ignorelist.com slows or prevents sites from loading

Status: UNCONFIRMED

(Firefox :: General, defect)

Description

[ff.noush]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2
Build ID: 20110902133214

Steps to reproduce:

Tried to load websites.


Actual results:

On several sites (e.g., Amazon, Chase Bank), loading pages has been slowed down or completely impossible. In the status bar at the bottom of the browser, I see FF trying to connect or is waiting for myprofile.ignorelist.com. Several others have had this issue and it doesn't seem to be virus-related (view: http://support.mozilla.com/questions/863221).


Expected results:

No slow down in connection. No attempts to connect to myprofile.ignorelist.com.

This are actually two issues:

1) Insertion of myprofile.ignorelist.com into all pages
2) Firefox freezing on slow DNS lookups and invalid servers.

The second issues is well known, so let's concentrate on the first one in this bug report.


*Which Addons and Extensions do you have installed?*


Some unknown Addon is inserting links to myprofile.ignorelist.com into all pages. The most likely reasons for this is some kind of tracking or advertisment blocking. myprofile.ignorelist.com has a DNS entry pointing to 127.0.0.2, which is an IP-address on the pseudo network within your own computer. Depending on the operating system configuration and whether you have a local computer, request to that IP address are very quickly rejected or delayed for some time.



I don't have the issue myself, but I found CSP violation reports for myprofile.ignorelist.com in my log:

{
  "csp-report": {
       "request":"GET http://stendhalgame.org/item/documents/blank_scroll.html HTTP/1.1",
       "blocked-uri":"http://myprofile.ignorelist.com/js.php",
       "violated-directive":"default-src http://stendhalgame.org"
  }
}

I've had trouble with the same thing and tried stopping of my addons but it was still happening.  The only thing that worked for me was another addon called Blocksite.  I entered the domain and Firefox immediately stopped trying to access that domain.  Having said that would it not also work to add 127.0.0.2 myprofile.ignorelist to the hosts file in system32? I tried 127.0.0.1 but now I see why it didn't work if they were using a dummy DNS. 

I tried to contact them by the way and was forwarded to afraid.org.  This is the reply I received from Joshua Anderson on afraid.org "This DNS was suspended in August of 2011 for abuse of freedns.afraid.org's terms of service".  This would answer why you had the csp violation you did.  The script is only running on the individual pc and isn't accessing anything externally any longer.

Do you still see slowness when using current version?
