We all witnessed AOL's bold move to offer a public download of 20 million searches that more than 500k of their users had conducted over a period of three months. The backlash from the Internet community and the media was enormous and as I expected AOL quickly fired three of its employees including CTO Maureen Govern. This does not help the 500k users whose searches are now publicly accessible though
If they would have used the Firefox extension Track Me Not the profiling of those searches would have been harder. Instead of using proxies and other methods to avoid detection the track me not extension sends periodically bogus searches to major search engines. The main goal of track me not seems to be to avoid the profiling of users by search engines. It is hard to say what they actually do with the data but a possible scenario could be that they either sell the data to marketing companies or use the data for their own marketing purposes.
Track Me Not runs as a low priority background task in Firefox "that periodically issues randomized search-queries to popular search engines, e.g., AOL, Yahoo!, Google, and MSN." Track Me Not is currently able to generate three million static queries and further versions will most likely generate the fake searches dynamically to further improve the method.
Update: Mozilla recently has introduced a Do Not Track feature in the Firefox web browser which is turned off by default. To enable it, click on the Firefox button and then on Options. Click on the Privacy tab in the preferences window, and check the Tell websites I do not want to be tracked option there if it is not already enabled.
This sends a do not track header to all websites that you connect to letting them know that you do not want to be tracked.
TrackMeNot may prevent search engines from creating a thorough user profile. It does not prevent them from creating a profile though, and the only difference in this regard is that the information may not be accurate due to the bogus searches that TrackMeNot conducts regularly.
The extension is still available and seems to work just fine. It displays the most recent search term in the lower right corner of the Firefox window.
