las versiones antiguas eran buenas, ahora las ultimas dañaron todo, para descargar un video salen un monton de opciones que no sirven, al menos salieran los tamaños de los videos para saber cual descargar

Used to be ok, now it doesn't work and they still ask money

Used to be good addon

I'm deeply disappointed with the developers decision to charge $30.50 for a premium wrapper for ffmpeg. So I am leaving this review to help others understand what you are actually buying for $30.50 (or the subscription fee).

To be fair to the Developer: Paul and his team built a very polished Link Sniffer and a nice UI. They also updated the 'Companion App' to handle HLS streams smoothly. For a non-technical user, this convenience has some value.

The 'Red Pill' Reality: However, the 'engine' doing the heavy lifting (downloading & converting) is still just FFmpeg, which is free, open-source software built by volunteers. You are essentially paying $30 for a dashboard that drives a free car.

Why $4.99 is the fair price: You are paying for the convenience of not using a command line. That is worth a cup of coffee ($5), not the price of a full AAA game ($30).

How to do it yourself for free (The steps they don't want you to know): If you have 5 minutes, you can replicate this 'Premium' functionality for $0:

Option A (Web-based & Clean): Use cobalt[dot]tools. Unlike other sites, it has NO ads and NO trackers. (Pro Tip: Smart users run uBlock Origin anyway, which makes the free web safer than many paid apps).

Option B (Power User):

Install 'The Stream Detector' (Firefox addon) to sniff the links just like this extension does.

Click it -> select 'Copy yt-dlp command'.

Paste that into your terminal with yt-dlp (free open source).

Verdict: Great UI, but the 'magic' is free elsewhere. Save your money unless you are allergic to keyboards.

It's with a heavy heart, I've updated my 2 year - 5 star review by changing it to a 1 star. 😞

Yeah, absolutely no one wants videos with watermarks added.

In order to actually be used, requires another program to be downloaded.

scam... it simply doesn't work unless you install an companion app on your computer, stay away form it

エラーだらけで全然使えない。詳細でもtxtにしかならなくて使い物にならない。

Ne fonctionne plus avec YouTube + Licence payé qui n'est plus valide

pay , or choose other solutions

Since a Firefox update to 116.0.3 (64-Bit), Downloadhelper doesn't wworks more. Very sad. Now I use the free Mediahuman without problems.

This extension used to work great for YouTube downloading. Now it hasn't worked in about a year. Supposedly it was fixed for a moment with version 8, but now it doesn't work again. Hoping that it gets updated and fixed, but I'm not optimistic after this long.

No I don't think I need external app to use this extension

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

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.

Upate 21 August 2023
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.

Garbage add-on! It won't download any videos unless you install the companion app.

It doesn't work, it requires an additional app to be installed (that for example on Macos it cannot be checked for malware), and even with that installed, it doesn't work.

When trying to download videos, another page opens asking to install another extension.

Капец, почти два ляма скачиваний, и нифига не работает; даже в настройках копалась. Ничего из видео всё равно не грузит, только картиночки .-.
