Hi, it should not be set as default as Google is the default.

So I do not know if this is the search or if it is your homepage that is now GoDuckGo.

To change your Search engine if using top right search box click on the Search Icon magnifying glass and change to another.

if it is set up still wrong please go to the 3 Bar Menu --> Options and then Click on Search . Change Default and can also remove goduckgo from the larger menu.

If it is set as your Home Page please go to what you want as your home page and in General --> Home Page click on Use Current Page.

Many thanks for this. Pkshadow said
