You’ll never be alone

● Google, Yahoo and Bing 'Track', 'Target' and 'Bubble' you. They:

– Tune your search results to what they know about you

– Send you annoying adverts– Limit the results to your searches

● Avoid this with Firefox or Chromium and the DuckDuckGo search engine:

– Firefox settings– DuckDuckGo settings

Tracking 1

● When you search Google, Yahoo or Bing:– Your search term is also sent to the requested site

– Unless you take precautions it will also be sent to other sites. You will be tracked

– Check your browser with Panopticlick https://panopticlick.eff.org/

Test Results

Tracking 2

● Who cares about which sites they visit?● Many sites have third-party ads, and those third-

parties build profiles about you, so they can follow you.

● Your profile can also be sold, so if you had a cold sore and looked up 'herpes', your insurance might go up.

● Your searches are saved by Google, and may be legally requested.

● The same applies to your email.

Firefox Search Engines

● You can add any search engines you like

● Click on ‘Manage Search Engines’ to change the order or delete the unwanted

DuckDuckGo

Firefox will check that you really want to install duckduckgo

Tracking 3

● Bubbling is when your search history is used to promote what you like, and demote what you do not like.

● Different people get different results.

Firefox - Security

If you share a PC with your dearly belovedand don’t want them to know what birthday presentyou have bought them, use the ‘Privacy’ setting.

– Use Lightbeam to see how successful it all is

● Some sites may stop working, but the measures can be reduced to make them work again
