Good, but... Rated 3 out of 5 stars

I use this plug in extensively but it's in desperate need of an update. Some of the searches don't work, and haven't for a very long time, though these are the less important ones and can be turned off.

Does not work with Facebook and some other major pic hosting sites, whereas equivalent plug ins for Chrome do, so it's obviously possible.
