Adding google search to Firefox on Linux Mint

Linux Mint has removed Google from the search engines available by default, and we have to follow a "Microsoft-esque" convoluted procedure to make Google search available from the address bar or the search box - following https://www.techbrown.com/add-google-default-search-engine-firefox-linux-mint/

• Go to https://linuxmint.com/searchengines.php
• Scroll down to the bottom of the page and click on the Google logo
• The page which loads up then has instructions to right-click on the address bar and add Google search from the context menu. 
• Then we can choose to make Google the default search from the search box from the "Change search settings" gear icon under the search box also.
