Satisfaction Beyond Description...

me gusto mucho en el pasado.

Actually lets you download 1080p60 video, without some kind of pay trap required like many other extensions. Yes, the audio/video are separate downloads, but I only wanted the video anyway. Combining them isn't too difficult, just google it.

AWESOME!!! It's working perfectly as advertised.
- No third party apps.
- No linking to external websites.
- Downloads (DL's) varied video resolutions based on available resolution playbacks in YouTube
- Download features video only & audio only

I'm using latest Firefox version, Win 10 x64 build 1803.

It's a "gray arrow-down inside a circle" icon beside the "Like" button for those who can't find it.
Availability of download resolutions are based on YouTube's specific video available quality.

HOWEVER, I hope and wish the developers would add a feature on download variable speed limit. I'd love that.

It's AWESOME! It really is! does the job, no third party crap or linking to external websites. I had been looking for an extension like this ever since the last i got became obsolete about a year ago. One thing, and I belive this is what is keeping you stuck not being the most popular youtube downloader extension ever, THE BUTTON IS IN AN INVISIBLE AREA. Yes, another guy already pointed it out. The button appears in an invisible area in the page, and in order to find it you must use the Inspector dev tool, search for "dowloader", and drag the button elsewhere. I you just fixed that it would have.. no, ok, I'll give this 5 stars, but you really should fix that.

I spend days (literally) looking for an add-on that could download high resolution files from YouTube (1080p+ video streams, as well as their respective audio streams). Unlike newbies, I didn't want an add-on bundled with third party crappy tools to joing the files for me, I can do that myself if necessary without compromising my privacy, safety and sanity. Unfortunately, after trying absolutely ALL YouTube download add-ons available on Moziila's site (except the obvious junk that use external sites for downloading), I didn't find any, until I tried this older add-on again, and what a surprise, it does do the job perfectly!

I had dropped this add-on before, because (1) it didn't show the high resolution files and (2) the download button didn't show up (it was added to the Page, but the DIV block was hidden, requiring me to manually move it out of that hidden block, what was too much trouble for a limited add-on).

Well, it just happens that both problems are solvable! First of all, this is THE ONLY add-on that shows high resolution links for downloading without using unnecessary third party external spyware, all I had to do was activate the options on its, yeah, options Page (why they come disabled by default is a mystery, but I guess the author got tired of newbies complaining that some video and audio files are downloaded as separate files, when that's the way it actually should be, as that's how YouTube delivers them).

Secondly, the "invisible button" is a problem of YouTube's new front-end design. Using other add-ons (I'm using Enhancer for YouTube, which allows adding a script to force YouTube to use the old front-end). Voilà, add-on working nicely!

I simply cannot believe that absolutely all other add-ons are used to exploit naïve users into installing spywares into their browsers! They claim that it's impossible to download high resolution files from YouTube (on of them going as far as saying that YouTube only delivers incomplete URL, so only itself and external tools could retrieve them). Shame on them all!

Anyway, thanks to the authors of this add-on, for keeping it alive despite Mozilla's and Google/YouTube's wild changes of mood and for being fair to their users!

Suggestion: you could move the button out of YouTube's Page and put it in the context menu or on a toolbar button, so it wouldn't depend of YouTube's front-end anymore.
