I guess that can be healthy since that plug-in is undoubtedly used for Google's own profiling to somehow sell more ads, heh.

Don't worry, there are additional blocked domains just for that. :-)

post a copy of your hosts.conf?

Pretty much this: http://someonewhocares.org/hosts/

Note that certain adware/spyware domains, like google-analytics( look at the tags <maybe-spy> and <maybe-ads> ), are commented out, so edit the file as per your needs.

Google's re-capthas are coming from google.com, to block them add:

127.0.0.1 google.com

127.0.0.1 www.google.com

This may be a tough choice to make, depending on how integrated has Google become with your life ( note how I phrased this relationship ).
