does not work out of the box Rated 5 out of 5 stars

first: i read a lot here before i was willing to test and likely buy this piece of software later because of the good price.
so i just installed it on my ff7.x
after restarting, i navigate to a normal page which contains some simple imagelinks to test the addon.
after clicking the button a new tab opened with nothing more to see as:

Gallery created by FoxySpider (and some lame facebook text)

i guessed, there could be problems with other installed addons (or whatever reasons), so i installed ff7.x portable and then only this addon.
starting the portable version and going to the site with the simple imagelinks and pressing the addons-button worked as expected. an image gallery was shown.

so that leads me to the point on which i need to check, WHY my fully functional configured ff does not work with the addon (or the addon does not work with my ff...i don't care)

because i did not find any help anywhere, i will write the developer.
if he can help me, i will add some info here.


EDIT:
great. both the support from the developer and the addon itself.
i was able to test it the 30 days and i must say it's a quite useful and good working tool.
imho, its worth the price you pay and there is nothing to complain about.

you can download all the images from a website you like to and you don't have to install 3rd party software on your computer (beside firefox and this addon of course), thats why i choosed it as my favorite tool. quick & easy. intuitive.

Only thing, i'm missing, is that no Imagedimensions are shown in the resulting tab. That would help decide which images to download.

This review is for a previous version of the add-on (1.3.4). 

Thank you for your review. I am not familiar with a compatibility issue with Firefox 7 (and in fact FoxySpider does work on one of your machines with FF7). I will appreciate it if you get in touch with me directly (foxyspider@gmail.com).
