None of these "YouTube Downloader" helpers have been working for a while now.

Do not spend money on these things, they're all broken until further notice. Youtube changed too many things and now all of these are broken.

(PS: can you detect the fake 5-star reviews? Use your head people, it's easy to see when the author is engaging in fake reviews for an add-on that doesn't even work).

плагин последней версии (10.22), Firefox win64 (115.6)

Опять не появляются ссылки для скачивания на сайтах:
ok.ru
vk.com
youtube.com и так далее...

Зачем (опять!!!) выкладывать не работающий плагин??

found no Links

not working on youtube . im removing it till they fix it

1. Sometimes the downloading part does not appear on the youtube video. Why?
2. Even when you place ss between www. and youtube, it doesn't download!

Давно не скачивает через кнопку в Ютубе. Скачивал последнее время через ss - сегодня перестало работать и это.

Sadly does not support properly facebook anymore. Videos like relations, rolls etc can not be downloaded because the add-on icon does not shows up on those media like it did previously.
Additionally the user-script variant of the add-on notoriously popups very irritating ads on the pages about some "OrangeMonkey" add-on. Those can't be disabled or turned off.
Sorry folks, but I won't use such OrangeMonkey junk just because you want me to use it.
Just f-off with that crap please!
Such nasty behavior should be also reported to Mozilla due to the violation of their rules!

From the pop up page after clicking on the icon:

Subject: Discontinuation of Service in the United States

April 16, 2020

Dear Savefrom User:

As you may have heard, our industry has been under strenuous attacks by certain US copyright holders. Because of these attacks, it has become financially impractical for Savefrom to continue to provide services in the United States.

Accordingly, Savefrom will be terminating its services in the United States as of April 28, 2020.

We thank you for your past loyalty and patronage and wish you health and safety during the present health crisis and beyond.

Very truly yours,

Savefrom
