so far so bad Rated 1 out of 5 stars

I've tried it on a number of sites, big and small. Nothing so far [Windows 7, Firefox 28]

Please give me links to the sites.

option for FILTERS Rated 5 out of 5 stars

Please add an option for FILTERS.
Size. Only BIG or SMALL images.
Scroll only through images of a specific range size.

Type. Only JPG or PNG.

And others like:
Width: only the images that are at least NNNpx width.

In some sites like Wikipedia the Alt Up behavior does not work well.

Sorry, I will not add options — don't want to complicate the logic of add-on.
I checked wikipedia and alt+up working for me, can you find a page where not?

Useful addon Rated 4 out of 5 stars

Well I'll try to write in english. This addon is a good idea and it will be better if it could be connect (in option for example) each people with the addons firefox website of its country not only with the US addons website. For example, the french with the french addons website, the german with the german addons website, etc ... I hope, even with my bad english, you will understand what I mean.
