Confirming a great Alernative Program! Rated 1 out of 5 stars

As "Kevin" already pointed out . . . there is a most excellent alternative add-on program called " "context-menu-image-saver" found right here in the add-on section. THIS will be my new go to program for quick image adding to various folders and it automatically can rename them if a duplicate already exists. So long "Save image in Folder". Thanks to Kevin for the most exclllent find.

This review is for a previous version of the add-on (1.3.10). 

I feel so happy for you, Mr. Cobra. Thanks for sharing your thoughts. Be safe. ;-)

How long till a Fix? Rated 1 out of 5 stars

Well like everyone has already said, this flat out no longer works in version 18 of FF. It was a five star program prior to this and I can only hope the functionality is restored. Until then, I'm on a search for something similar and if I find it I will NOT be back.

Frankly, I'm sick of lazy developers who drag their feet supporting their own creations. If it's not important to you to refresh them well then that's fine. However, it will also no longer be of importance to us to support you. Products that have been abandoned should be removed from the site and developers who repeat this should no longer be accepted for future programs. I'd much rather see fewer programs that are truly functional than wade through a ton that are no longer working or being supported.

This review is for a previous version of the add-on (1.3.10). 

Wow! Nice speech. :)
I have nothing to add.
Enjoy your future Firefox-experience, Mr. Cobra. ;-)
