This addon detects Blogger local domains like http://diegocg.blogspot.com.es and redirects to the international version of the url, also asking the website to stop using the local domain, as documented in https://support.google.com/blogger/answer/2402711
Starting with version 5, it should be redirecting all Blogspot domains, but in case there is a domain left out, it can be added in about:config extensions.no-more-blogger-redirect.domains. You can also report the missing domain to add it by default.
There is an option in "Addons - No More Blogger Redirect - Options" to enable a mode compatible with NoScript. It is NOT recommended to use this mode if you don't have NoScript ABE ( https://noscript.net/abe/ ) enabled.
