Very good when i want to download porns

Addon never works, it does not download any videos (on any website that has video embedded). All it provides are tiny "video" files, none of which are the actual video! I have used many addons over the years, this is definitely a faulty one. Judging by other revews, a scam and stealing data doesn't sit well with me after being hacked a few years ago!

it doesnt work.

nice

Scammish. Doesn't record live streaming videos. Gives you a hit, and then takes you to a page where it wants you to pay $20 or more to download the Ultimate version which apparently gives you the capability. I have no problem paying but be upfront about this being a paid app from the start.

A short trial of the software (a few days to a week) would be good to let potential customers test out the basic features to determine if this is the extension they want to use and spend their money on.

It is unable to identify playing streams and just shows ad for downloading their android app

This is suppose to be one of the best downloaders. I beg to differ. On about 1/2 of the time it can't even detect file download links or streaming links even with all ad and script blockers turned off. I have to use "Video DownloadHelper" instead. My old XP64 with FF52.9esr and "Flash Video Downloader 16.3.8 by Paul Saint" is/was better by leaps & bounds, and I am still using my old system. If Paul Saint reads this, I beg you, PLEASE, PLEASE upgrade your old Flash Video Downloader to work on the latest FireFox browser.

This addon does not download 4K videos. It opens another page on the Internet where you have to pay 19.99$ for this functionality.
That's why the words ''- supports up to 4k videos'' are a lie. Now it does not support 4K if you do not pay.
WARNING! NO 4K
I will find an addon which can do what I want without paying 19.99$ because maybe for you 20 dollars mean 3 cups of coffee, but in my country it is one week of buying food.
IMHO< the author should mention that you have to pay, in the description!
Anyway, I have tried 6 other similar addons, and 2 scripts for Tampermonkey, and none of them did what they promised, they did not download 4K or were not free, or wanted the user to use command line if they need 4K.
I will have to continue using web-sites for downloading YouTube videos, and hopefully Firefox can make it easy for developers to make a functioning 4K downloader.

only add-on I could find which also downloads Spotlightr videos

It is a reliable add on

Doesn't work. Dev is Trash.

One of the best working Download helpers for Videos.
