Comment(by offthewheel):

 This is somehow relevant to your TBB issue of add.my.yahoo.com:

 Not using Tor.
 Using Firefox 12 through Comodo Firewall.
 Firefox about:config has had the "add.my.yahoo.com" entry removed as
 recommended above.
 BUT, if Comodo Firewall is set to block "add.my.yahoo.com"
 then Firefox will not open some web pages  e.g. https://www.startpage.com

 Comodo Firewall writes to the DNS Cache.  The DNS Cache may get flushed by
 other apps, or the DNS TTL expires, which can make it seem like everything
 is working ok, but then Comodo Firewall updates the DNS Cache and Firefox
 is broken again. (This is theory) Also DNS Cache gets very large by Comodo
 Firewall, which is slow to rebuild & recache, which hinders debugging.

 I had to put the "add.my.yahoo.com" into the hosts file as a 0.0.0.0 entry
 to get around the problem and still block it.

 This "add.my.yahoo.com" entry is bug or spyware for Comodo Firewall
 possibly, or it could be hardcoded into Firefox in spite of the
 about:config setting.
