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.

Where is it? Not on the Address Bar with the others. I see it in Add-Ons but there is no option to put it on the Address Bar. Brilliant. Well done idiots!

Its weeks later. Still can't see it. What is the point of releasing an extension if we can't see it to activate or use it? Please tell me. Are you utterly mindless?

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.

Works great, but it appears in a hidden HTML spot. I have to open up the inspector, search for "downloader", and drag the button so it's below "info-text", then it works as intended. It'd be great if it was fixed to appear in the right spot again.

Update: v.0.2.4 fixed my issue! Thank you! It now works and appears properly. It will require a tool to mux after download for quality above 720p. I recommend MKVToolNix.

Thanks for the quick fix, I thought YT changed their stuff again just this Feb 2018. I'm glad this add-on can download those videos agian. This is my top-rated YT downloader, especially since it can DL those separate DASH streams (eg. M4V video, Opus audio) while others can only offer combined MP4 and WebM.

excelent

Funciona um pouco mal com o novo YouTube. Por vezes o botão não aparece. De resto funciona bem.

Perfect and Light :)

only shows low res video's both mp4 and webm up to 360p including extremely small flv 144p and 240p
I understand 480p and 1080p are dash only but 720p should be available in both mp4 and webm (I tested it on new videos available in full HD)?
I'm running FF57 x64 on 7 x64

edit
I enabled DASH to see if google changed something and 720p was DASH only
sadly even with DASH enabled no HD video is available only up to 480p and I tested it on a 2k video

was working very well but doesn't work anymore since FF57 (W10 64bits)
