Here’s a great extension for firefox that will tell you all kinds of SEO-related information. All accessible with a right-click. Isn’t open source great? It allows people to do things that make life more productive and it’s easy for them to do them. The guy who wrote this probably does a lot of SEO and just wanted to make his life easier. Since others have released a great open-source tool (firefox) that he’s using and benefiting from, he decided to also release his for free.
Win one for open source.
