How to get Google search suggestions in Firefox on Linux Mint

The Google search feature is not offered as an option in the version of Firefox that comes installed in Linux Mint. You can add it with the Manage Search Engines feature, but when you do, you will notice that there are no search suggestions when you start typing a search term.

To add Google search suggestions, you need to edit the file google.xml, located in the searchplugins directory, inside your Firefox user profile. In my case, the full path for this file is:

/home/marios/.mozilla/firefox/mwad0hks.default/searchplugins/google.xml

Yours should be similar, and the command locate google.xml can help you find the path.

Edit that file, and add the following line:

<Url type="application/x-suggestions+json" method="GET" template="https://www.google.com/complete/search?client=firefox&amp;q={searchTerms}"/>

...somewhere before the closing </SearchPlugin> tag. Restart your Firefox, and suggestions should now work.
