cannot get help in activation Pro version.

Because you have to pay to download mp3 WTF !!!

In oorder to use it you have to buy it
Чтобы пользоваться надо купить

Doesn't download mp3s unless you pay for it.

Unable to download mp3 files without "upgrade"
YouTube switched to separate audio/video streaming technology for higher quality formats and no longer provides direct 1080p/mp3 streams. Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users.

"...therefore 1080p/mp3 downloading has been limited to PRO users." = Waste of time, instant uninstall

Site down or something ? Fix please.

it pushes trojans which shows adds many times. Also I found that my saved passwords got leaked after installation of this addon. Beware guys you may be watched.

Not free

Worked great, since I paid for it, but after reinstalling Windows a week later, it's gone. I tried contacting these guys, and said I have a PayPal receipt that's only a week old.. No Response. That was several weeks ago, still no response. I won't give them any more money. I found another one that works better, downloads HD and is free.

This developer is not correctly informing you that you cannot download high definition, 1920x1080 or greater, videos from YouTube or other streaming video sites without needing to pay the developer for this service. If this were true then, you would not be able to use an open source project like, youtube-dl, to download these high definition video streams, which you can still do as of today. Also, there are many other download managers, such as JDownloader, which can scan the URL and download these high definition videos. So, this is a devious tactic by this developer for financial gain only, as opposed, to being upfront and honest about wanting more donations. They are making up an excuse and blaming YouTube or other sites that offer high definition streams. Try for yourself, using youtube-dl, VLC, JDownloader, IDM, etc. and you will see that you can download these high definition streams.

Garbage

not free for hd with audio (mp3)

none of this shit works!

No permite hacer ninguna descarga en MP3 y dice que se debe hace un upgrade visitando una pagina web.

Does not deliver what it promises.
Removed after 30 seconds.

Version 19.1 does not work. anybody who posts saying it does after Oct 2024 is spreading fake news.

the developers lie saying they had to make mp3 download a pro paid feature saying that YouTube changed thing and they have to use there own servers to process it, this is a lie i just used another free one called YouTube mp3 to download the mp3 for free only took less then one minute, https://addons.mozilla.org/en-US/firefox/addon/youtube-mp3-revised/?src=search

cant see extension in browser

Doesn't work.

I'm giving 1 star only, because the developer of this add-on wants to deceive users.

1.:
This add-on DOESN'T support downloading 1080p videos for free. You have to pay for that.

2.:
When you try to download an 1080p video with the free version, you'll get the following message:
"Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users."
This is an obvious lie, since downloading these videos doesn't need third party servers at all, but it's a good excuse to harvest some money from the unsuspecting users.

Other 1080p youtube downloaders use ffmpeg on the users' computer to merge DASH streams together, so there is absolutely no point using third party servers for that. That's the safer, faster, cleaner and cheaper option, so don't get yourself scammed.

I see no way to use it. Its in Add-Ons but not in the taskbar. I see this frequently with Add-Ons. Not sure what they are thinking. Make a product then hide it making it impossible to use. Brainless.
