should be a builtin feature Rated 5 out of 5 stars

Takes a great interface detail from Opera and makes it even better with the instant load a la Google. The builtin plugin list is very useful and adding another one is as easy as it could be. I hope Firefox adds an identical feature to the standard browser since only a small number of users will bother with finding and adding a minor tweak that doesn't fix a security flaw. For those who love the keyboard it is fantastic.

This review is for a previous version of the add-on (2.8.2.1-signed).
