R3byR2

Now, easily add reviews right from a web page. The extension will automatically figure out what type of content you are trying to review - video, book, or just a web page. 
This makes it easier to add your reviews, as you can add them without leaving the web page, and without having to copy / paste the URL into R3byR2 web site.

Using this extension, you can not only add you rating, but the full review as well (tags included).

For the first time, you will be asked to login (if you are not already logged in).
