Der Video DownloadHelper arbeitet sehr gut. Ich habe keine unerwünschten Nebenwirkungen festgestellt.

And another re-edit: Seems like Github is not a good solution to collect failure reports. Yesterday I reported a complete YouTube DL-failure - what wasn't replied at all. Today another user reported the same failure. But I was blamed to having posted twice (!!!) and caused by this the risk for the account owner to be 'sued' for SPAM - Guys, by now I won't any longer report ANYTHING! If it won't work in the future - well, bad luck and uninstall!

Thank you and 2* !

I've owned and used for many years, usually with the companion app. Basically stopped working with YouTube over a year ago, but continued to work on a few other sites. Now as of Aug 2023, it gets nothing at all. I get messages about not being able to aggregate streams, regardless of video type or size I try to download. Definitely don't pay for this

This is an amazing app. I can't find the words to describe all the convenience it has given to me. What others hide, it brings to the surface. :) be blessed! ♥

某J、FC動画がダウンロードできて重宝してます。ありがとうございます！

Nice Add-on. But Latest Version has no function "2K/4K" Youtube video saving.

Melhor app para baixar vídeos. Salva vidas, facilita tudo. Excelente, baixa tudo muito rápido, grátis, simples. Não tem melhor!!!!!

molto buona anche se in certi siti si fà fatica a scaricare perchè bloccano il down e in altri non sincronizzo video con l'audio ..purtroppo noin posso contribuire in questo momento per supportare lo sviluppatore ..ma spero di dare con questa recensione di dire che rimane tra le migliori se non la migliore..by by

Mir gefällt der Video Downloader sehr gut . Er ist einfach zu bedinen und vor allen können Leute die nicht so viel Geld haben benutzen. Vielen Dank Dafür.

14 Aug 2023: Does not work. Paid $28 U.S. and can't get a refund. I want a refund. No videos download. It indicates "downloading" but just sits there...dead. I've tried several video sites but none work. I have the latest v8 *.tpi and I have latest 1.63 companion app and I have paid the "premium" fee of $28+ U.S. Beware because there is no way to get a refund. It's just money lost. Yes I have uninstalled and reinstalled several times. I have also tried manually removing the *.tpi from Firefox as a prep to do one of the many reinstalls. Video DownloadHelper (VDH) just dead and there is no live support. The so-called "forum" has nothing but people like me who know nothing but need help so we have idiots trying to help idiots and the only suggestions are: (1) uninstall and reinstall, (2) clear the cache, shutdown and restart. I've done all of that. No good. I have 3 computers and Video DownloadHelper is not working on any of the 3 computers. That's a clue that the failure is not something I'm doing incorectly. Is it my ISP blocking? No. I fired up my VPN and tried downloading to those 3 computers. All 3 have Video DownloadHelper doing nothing but sitting there stating it is "downloading" but it is not. I am thankful that I have other Firefox extensions for video and they are working. Those other Firefox video extensions work and they are free with no QR watermark and they don't charge to remove a watermark. Video DownloadHelper ate my $28 U.S. and just sits there and hides behind some 3rd party billing service that I cannot contact to refund the charge to my credit card. Video DownloadHelper states that PayPal won't deal with them. Well...now I can see why PayPal has shunned them. This is scary because VDH stems from the github. I trusted them. Now I can't believe in anything anymore.

Update 15 August 2023
I have contacted sales@downloadhelper.net on 14 Aug 2023 and 15 Aug 2023 trying for a refund. It is that email address from which the registration key was sent. I am getting no response. The email address is just as dead as the Video DownloadHelper servers are dead. It's all dead to me. Black hole. Dark matter. Empty void. Money gone. Now I'll be forced to engage in the credit card dispute process for the charge made to my credit card.

Update 19 August 2023
They ignored my repeated request to cancel my premium payment so today I filed a dispute with VISA. VISA issued a refund to my account and VISA states they will take it from there. Over the last several days, I've tried Video DownloadHelper at several of the sites it states it can manage. None work. Sometimes it will download the advertisement prelude but the topical video is never captured. Maybe it's just me because I am seeing people post their successes with the addon. I have updated the browser, updated the add-on, and updated the companion application. I have reverted to older versions of each to run some tests to see if I can discover an algorithm that brings about a successful download. Hours I have tried and achieved only failures. I seriously doubt it is anything I'm doing wrong because I've tried several computers where each computer has different configurations. In all cases, other Firefox video downloaders work fine. It's only Video DownloadHelper that continuously fails.

Today, a glimmer of hope shone through the Firefox GUI. VDH did work once at a non-YT site. I'm running out of text allowance so I have to be brief now. Anyway, it did work once today. Maybe there's hope.

I gave a FALSE 5 stars to get it back to how it was before.

Was working fine on Aug 13, 2023. Now on the 14th, crap. Adds a QR code again to encourage ''donations'' after a long and useless conversion process, which it didn't do YESTERDAY.
I'll give it 5 stars again like I gave it before but for now it's 1 out of 5 stars.

J'ai donné un FAUX 5 étoiles pour que ça revienne comme avant.

Fonctionnait bien le 13 aout 2023. Maintenant, le 14, de la merde. Rajoute à nouveau un code QR pour inciter aux ''dons'' après un long et inutile processus de convertissement ce qu'il ne faisait pas HIER.
Je lui redonnerai 5 étoile comme je lui donnais avant mais pour le moment, c'est 1 sur 5 étoiles.

Works very well! Thanks for the addon!

Works perfectly well once I got the hang of it and added the helper companion app.
