Rated 4 out of 5 stars

The add on is great, but it seems that it causes firefox to crash when you try to open a high resolution image with it activated.

Other than that it's excellent for what it does.

This review is for a previous version of the add-on (3.0.4.1-signed.1-signed). 

I just uploaded a fix, which I've been sitting on for far too long. Sorry about that.

(As far as I know, 3.0.4 hangs if a) there are multiple spaces in a row in the image filename, or b) you're using either the Greek or Luganda locale. If it still hangs in 3.0.5, please email me.)
