Review edited to reflect the latest update. The new 'Block content on any page' setting permits the page you're on to tell the extension to disallow downloads. So now YouTube, for example, sets a cookie with this extension and you can no longer download anything from YT. This extension is now basically useless.

It used to work just fine. Now, it's just crap. No one wants videos with watermarks.

This app requires you to download a program to your computer. Do not download.

tl;dr: 3rd party app installers req'd by this extension fails malware test on virustotal dawt com
Dev is very vocally frustrated about their OSS extension flagging spuriously in VirusTotal.
TO BE CLEAR: Their code is clean, if/when audited.
**The MAJOR problem is with their installers that are SUS AF.
**The solution: d/l their code and build it locally on your won machine, bypassing their sus installer apps.
**If you can't DIY, don't even think of installing on a machine you use for secure purposes like Banking.

Ahora te pide descargar una aplicación externa a firefox para poder funcionar... aléjense de esta extensión.

I download videos to play them back later using VLC and playing at double speed. This video download tool did not download videos with sufficient clarity to allow the double speed. When I speeded the playback up, the soundtrack was broken up. It would play for a few seconds, then stop for a few seconds, all the way through the video. The soundtrack had an intermittent clicking or popping sound at normal speed like it was barely keeping up. This extension could be a good tool if the soundtrack problem were corrected, but as it stands, it is not yet ready for prime time. FYI, I was downloading from a Kajabi storage site when I had this problem. The sample YouTube download you suggested in your installation process worked fine. Your extensive made me download an app from another vendor, MIG, to effect the download process. I don’t know if the problem came from your extension or that app, but they want $28.50 per year to use their software, and given this problem in downloading, I chose not to use or pay for the MIG app. Please let me know when you’ve corrected this, and I’ll try again.

Requires a companion app to do anything. Do not install this.

Ha dejado de funcionar, posiblemente el creador quiere que compres la licencia.

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
