Disable Google SafeSearch by visiting the search settings page. The search settings page can be found online by typing google.com/preferences into the Web search bar.
Once you get to the search settings page, you go to the SafeSearch filters section. Make sure that the box labeled "Turn on SafeSearch" is unchecked. Unchecking this box disables the SafeSearch feature. You can go back and enable this feature at any time, if you change your mind. After you have made your changes, click the save button at the bottom of the page. Once your settings have been updated you can go back into Google and search without this feature enabled.
