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.
Why no google search?? Rated 3 out of 5 stars
It seems like the obvious first place to search for images (along with Tineye, which is also excellent) Why is a Google image search not included? Hope you'll be adding this in the next update.
The 'do it all in one go' option is particularly useful.
Update to version 1.1
Thank you. I've replaced the defunct GazoPa with Google Search by Image.
