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://cup.aihedy.com/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.

no longer provides direct 1080p/mp3 streams. Want money to upgrade

Doesn't work. Downloaded videos are 0 Byte files. For HQ you have to pay.

Requires you to pay to be able to download 1080p.

This used to be my favourite add-on to download from YouTube. Now, it doesn't allow downloading separate video and audio streams, requiring payment... Really? If I would ever pay to download from YouTube, guess what, I would pay to YouTube for downloading, not to third party. Edit: as of Feb/2023, it's still a click bait.

I just discovered that another add-on has options to enable showing the high resolution file links, making this add-on fully useless.

If you're going to charge for certain resolutions, make that clear up front, and don't make users go digging to figure it out. Also, don't make it seem like users can donate whatever amount they want. You have specific amounts, so it's multiple choice, not any amount you wish.

It has ads, it's not offline and It sends the videos you watch to videodroid.org, and apparently they charge for 1080 but the claim they're the only add-on to support 1080p is blatantly false!

They use some obfuscated code which is allowed by Mozilla but it is against the provisions of the MPL license:
" “Source Code Form” means the form of the work preferred for making modifications." If your preferred style of coding is writing unmanageable and unreadable code then fine but If you don't want "Script kiddies" copying your code and modifying your advertisements then also change the license to something more restrictive!

Using obfuscated code is sketchy as hell anyways and usually a tactic by malware authors but I'm sure that's not a problem for you! While Mozilla reviews the "human readable code", let's not forget that Stylish a highly popular add-on was stealing users browsing history for months before Mozilla finally did anything!

not working, generating, generating, generating, generating, ..... and nothing

not work on new material design

link after donate I can't download FULL HD right now

Can't download 1080p with this addon unless you "go pro"...what a joke.
