there are plenty of discussions about it. I didn’t find full solution. You can add google as a search engine. But suggestions don’t work for me.

My approximate solution

  1. remove standard firefox:

     sudo apt-get remove firefox
  2. remove search addons. Source. I am not sure if this step actually helped. TODO: Check if it is required.

     sudo apt-get remove mint-search-addon
  3. delete file (or rename to have a backup):


    and contents of the directory:

  4. download, install and run firefox from official website. It will create a new version of

  5. in .mozilla/firefox/sf8ha7dx.default/searchplugins create a file google1.xml with contents:

     <SearchPlugin xmlns="">
     <Url type="application/x-suggestions+json" method="GET" template=";q={searchTerms}" />
     <Url type="text/html" method="GET" template="{searchTerms}" resultDomain="">
  6. remove official normal version of firefox

  7. install mint version of firefox:

     sudo apt-get install firefox

    Now “mint” firefox will use search.json.mozlz4 version from normal firefox and suggestions should work

  8. Optional. I also removed (actually renamed) from /usr/* all directories like searchplugins that contain files like yahoo.xml. I think they are created by “mint” firefox. Not sure that it is a necessary step. Further check is required here.
