For me yes it has.............. I dont know why or how people get different result using the same program but some seem to. FF has an array of programs (all free of course) all about privacy , Privacy Badger deletes your cookie as soon as you leave the site.....Facebook fence -puts a fence around Facebook stops it following you when you sign out--- There is a free VPN if you want to use it---- most programmers put their new stuff on there to try out---you can send a small donation to them if you want--but mostly they want feed back from the millions who try it. I am not really up on computers, but I do find its an easy one to use.
