Duckduckgo and Google Ghrome
As I am running code club at Paignton Library, I need to use Google chrome, as this works really well with Scratch. It make it easier to manage some aspects of code club from home.
In order to mitigate what chrome does as a browser. Once I had installed, on the first run I Opted out of having chrome as my default browser and also opted out of the tracking it offers.
The first thing I did. was to switch my default search to duckduckgo.
First step click on the URL box and select Manage search engines

You will then see the list of search engines. I have already taken the step of adding duck duck go to Chrome.

You need to remove the unwanted search engines with the menu

Note: in order remove google as a search tool you need to make duckduckgo default then go ahead and remove google.
