there is some of points for this extension :
1.This extension does not include many servers. There are only Germany, the Netherlands and Canada.
2.This extension needs to be developed in order to become stronger, because sometimes ads and clips appear on the page that do not belong to the country in which we use the server for which the user is used, meaning that the server is penetrated by local Internet providers.

Excelente extension modo gratis para desbloquear las pagina y accesos a la web funciona bien tanto firefox como otro navegador
