This one is a mixed bag. On the good side, it works well and effortlessly. No doubt about that. I mostly use it for one site only and it works seamlessly with that site.

On the other hand, there are 2 flaws with it that make me take down the rating to neutral. Its not the generic UI or anything, that is fine. Functionality over Looks.

1. It requires setting a default download folder, which I have never done since I started using firefox over a decade ago. I always need to save files all over the place, and this extension now forces me to set a default download folder. However, the developer has mentioned this in his description, so this is not something egregious. But I do wish the developer can address this by having an option to set a default folder option within the extension.

2. This one is egregious. It CANNOT handle simultaneous downloads and CANNOT skip already downloaded files. So, if I am downloading from one webpage and I start another wenpage before the first one completes, it aborts the first one midway and starts the new one. Then if I reload the first one, it does not skip already present files, but rather renames the duplicates and downloads them.

3. (EDIT) I have no idea how the thread sucker option works. It sounds like something useful, if I want to rip images off a particular post in a thread, and not the whole thread, but there are no instructions or hints on how to use it.

All these are very basic areas where the developer has made compromises, which is why I am rating it a neutral 3-stars.

I hope the developer takes this as a positive feedback and updates the extension to handle these basic intuitive conditions.

EDIT: Support for imx.to and vipr.im (which is basically imagetwist) will also be greatly appreciated.
