Freschy is a malvare http://www.spywareremove.com/removefreshytoolbar.html

look at FredMcD 's answer in this link https://support.mozilla.org/sv/questions/1041810#answer-678575

SpyHunter did NOT fix the http://services.freshy.com problem, did even find it.

Same for ESET OnLine Scanner & MS Safety Scanner.

Your System Details list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts. The user.js file is only present if you or other software has created this file and normally it wouldn't be there.

You can check its content with a plain text editor (right-click: "Open with"; do not double-click). The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.

Deleting user.js did the trick.

Thanks.
