locate this file on your box, ignore the path if you don't use linux:

/usr/lib/firefox/distribution/searchplugins/locale/en-US/amazondotcom.xml

it should look like this:

pro tip: search box dropdown (clickly ye olde magnifying glass), Change Search Settings, remove amazon, restore default search engines.
