Large letdown. Does not work at all.

A program/utility/addon should be rated as a sum of two parts: the utility itself and the documentation.

The documentation provided by the homepage for MSI Multiple File Downloader I rate as F minus: horrible beyond belief.

As for home this addon works, I have no clue because the makers decided to put tons of information on their site, EXCEPT HOW TO BEGIN TO USE IT.

So, what don't I know: I do not know how to download files with it. It is installed. I have no clue how to use it.

Does not work at all. Icon appears last in three dot menu instead of normal place and is gray and unusable.

it's crap.

It does nothing, including showing up as an option. Firefox should remove this from its site. It's worse than a waste of time.

Just. Does. Not. Work.

It's an amazingly poorly written add-on where no one is able to use it properly. Not sure what are "MSI Developers" doing. For one, nothing shows up in the downloadable content list (it's always greyed out). Even when you do the stuff some enlightened person wrote in the reviews section (marking the pngs downloadable, for example), it now lists them, but still errors out and does not download them with the error "Unchecked lastError value: Error: filename must not be an absolute path" in the Browser Console. This shouldn't even be alpha.

It does not work. Poor tutorials and hard to find help with problems.

100% Useless. DO NOT WASTE YOUR TIME. Does not work as expected.

Multiple File Download button doesn't show next to address bar, even after i confirmed Enable it. So how can i use this extension if it doesn't show? Please fix this because DownThemAll has not yet release Firefox Quantum version. Next to address bar only has Page Actions, Pocket & Bookmark button.

Totally useless, no directions or indication it is on your computer. That coupled with no response from the developer leads me to think there is something nefarious going on here.

not usable - the button is greyed all the time

kein Menüpunkt zum Verwenden des addons, nichts im Kontextmenü, sofort deinstalliert

Any amount of instructions/documentation would make this even barely usable.

I have a Firefox Quantum 59.0 (64 bits) on MAC High Sierra. The button is on the menu but greyed out. Maybe because I am trying to download pdfs?

I see no answer from the developers so maybe this is an abandoned project? If you are out there I am willing to contribute documentation if you explain how this works.

i can see some users say coding is needed to make this work. i dont think this is user friendly for most users.

this does not work at all.
the icon is not pressable

It didn't do anything. Just sits there. I think its actions are suspicous.

Does not work for me. There is no toolbar button and I can find no way to activate the extension.
