Musthave Addon, but have issues with new version... Rated 4 out of 5 stars

Use this addon about 2 yrs, all works fine and does what it made for) ...But for me only in v3.3.7.
Just updated to 4.0.5, and it doesn't disable autoplay anymore. Same thing with preferred video quality. And after I installed "Youtube flash player" addon - the toolbar of YouTube Enhancer just disappears, and never come back, even If I switch both addons on\off and restart browser... Messing with options didn't help either. BTW, store addon options on local PC was much better idea, than that new webpage or smth like that in latest version :)
So I'll stay on v3.3.7 for now [it still works fine for me on Firefox 42]. Hope later updates would fix that problems.

Excellent. Rated 5 out of 5 stars

This is excellent, and works like an add-on by Mozilla themselves or a Google app ;) — nothing is to be added to this I guess.

By the way, I refrained from making a donation since I wanted to send you $3 but you set a minimum of 5.

Simple does what I want. Auto-Sets quality and downloads videos for educational purposes. Rated 5 out of 5 stars

Really wish it would recognize if there are other ad blockers installed. Sometimes the confliction between the two are nasty. Strange JavaScript error, I think it is more on YouTube's end but still only occurs with add-on enabled. Still attempting to find that button that shoves/minimizes it into a corner. If your curious about what Style to use for YouTube I would suggest (https://userstyles.org/styles/101409/youtube-dark-grey)

This review is for a previous version of the add-on (4.0.2). 

The toolbar can't be placed in the left corner anymore, but you can use the "Slide Effect". When this option is enabled the toolbar slides down and is almost not visible when you don't need it, and slides up as soon as you place your mouse where the toolbar is normally visible (i.e. at the bottom of the screen, just in the middle).

Might conflict with addon Youtube Flash Player. Rated 5 out of 5 stars

(v4.0.2) I'm on XP and it seems to be working [Edit: not working now, locking up - I guess the same bug the developer is currently fixing.]

I disabled the addon Youtube Flash Player. Firefox seems to be allowing Flash for youtubes again (not just html5) so it's not necessary anyway.

[html5 youtubes tend to stutter with old Windows XP computers, so a lot of XP users are probably using the Youtube Flash Player addon.]

The lockups and the other bugs have been fixed with the version 4.0.5.

Indispensable Rated 5 out of 5 stars

A posséder absolument, incontournable sur Youtube !!!

Le seul petit hic vient de la détection de la publicité qui est assez défaillante mais c'est un détail.

Must have if you watch YouTube videos Rated 5 out of 5 stars

Smart, set-and-forget app. Does what it does perfectly.

One wish: Automatically mute sound for the first few seconds before Enhancer Plus stops the video from playing -- and the unmute when I'm ready to watch the video.

Good addon Rated 4 out of 5 stars

Been a pretty good addon for awhile, though it's run into some problems with Youtube changes lately. I know the dev is working on an update to fix those problems so hopefully that comes soon and this will be a solid 5/5 Addon again.

All the bugs have been fixed with the version 4.0.5.

Perfect. YouTube Tool Rated 5 out of 5 stars

Tested lots of YouTube Download and plugins.
Downloads the MP3/Movie.mp4 true external website.

Just ignore the codec issue warning, use 'VLC media player'.

Exellent module !! Rated 4 out of 5 stars

Super travail !! Très fonctionnel et intuitif !!
Petit bémol concernant les options de blocage de lecture automatique...
Je suis vraiment gêné par l’impossibilité de voir la vidéo suivante même si la lecture automatique n'est pas désactivée....
Il y a un léger temps d'attente avant de bloquer la lecture automatique dans un nouvel onglet....
Y a t-il une solution ??
A part ça, super module, bravo !!

Merci ! En ce qui concerne les problèmes mentionnés, ils seront résolus avec la prochaine version que je suis actuellement en train de développer.

Sidebar feature Rated 4 out of 5 stars

Sidebar feature doesn't work anymore due to changes in YouTube API. Hope you could fix this.

Nice Rated 5 out of 5 stars

Thank you for the nice add-on. I have one wish though: disabling autostart does not work with the HTML5 player.

Great extension Rated 5 out of 5 stars

Really great add-on but I think there is one thing missing:

Disabling annotations and subtitles!

Really useful addon, all videos in HD, buffering even when paused and the dimmed lights just kinky.
