Review for Thumbnail Zoom Plus by Sam Bo
Rated 5 out of 5 stars
An option to add sites in a black list (disable on specific sites listed by the user). And if you can correct the wrong title when you download the image pressing your hotkey ( context menu + z ). Try google images, you can see that the name retrieved is almost always the size of the image.
This review is for a previous version of the add-on (2.3.1-signed).To create your own collections, you must have a Mozilla Add-ons account.
