Addon is great, one big flaw is that i have to disable and enable it every time after i have closed the browser for it to show up again.

Very good, here's my suggestions:
Add dislike button
Add disable ambient mode

Often, especially when the Browser screen is limited in width or when keep the YT page zoomed, the Addin Controls are to big and part of them (the rightmost in particular) no more available because of the space available (especially when are within the video player and almost all checked in settings).
So, It could be great if there's an option to change the width and minwidth value of the controls-buttons to visually resize and compact the tools (let's say, a set list of available values like 32, 48):
.ytp-chrome-controls .ytp-button, .ytp-replay-button {
width: ##px;
}
.ytp-efyt-button, #efyt-controls-button {
min-width: ##px;
}
For example:
- Browser Zoom 120%
- width 32px
- min-width 32px

All the Controls are now visible and available.

Per http://reddit.com/comments/2zr4y7 and http://reddit.com/comments/ypcsot, I'd like to be able to sort entries of playlists, especially chronologically. Considering that finding all iterations of `1 year ago` should be all that's necessary, I believe that this suggestion is reasonable. I wish that an issue tracker were available for such requests.

Very good enhancements for regular YouTube use

Awesome. Only complaint is the pop-up player icon sits on top of every video I play and there is no setting in preferences to move it - only resize the pop-up and choose quality of playback.

Please update the extension when possible so that we can move this little button - which I, personally, do not use very often.

Thank you for all your hard work and I hope you and yours have a happy holiday season!

Great Add-on!! my suggestions would be 1) Add a slider to the Progress bar to loop and repeat - rather then just the time window start and stop repeat - And if not possible allow time increments - like 11.25 seconds to 12.35 seconds as currently Loop is at a 1 second interval - this is not so accurate .. 2) can you add a zoom feature of a certain part or area of the video it self ? like as with windows Snipping tool ? Great add on .. Cheers to you !!!

One of the (if not the) best add-ons for Firefox. The only thing that's "missing" (that I'd love to have) would be the option of changing the aspect ratio of videos. There's a lot of stretched videos in 16:9 that were originally in 4:3 ratio. It'd be awesome to have an option to push them back to 4:3.

Maxime, could you be so kind to add m.youtube.com (youtube mobile) support? I moved from desktop version (via some addon that redirects) because it is way lighter on resources.

it's very good (love the suggested videos block, blank screen at end of videos, so good) [also appreciate the shorts block, very much so; can still view in a search result or channel, i guess ok, lol]
... except for a some things
I use other addons for
.continuous play (though it reverts to non-fullscreen)
,disable youtube miniplayer
.adblocking, don't need multiple blocks
.channelblocking, filtering
.downloads, i never use it though; meh
Some things you do i do w/other
Some things you don't do
... today the problem is Speed:
I clicked on a like button and scrolled back up in FS mode, and it maxes out the speed. It says 2x, but seems like 10x.
I can't duplicate it, but it happens a lot. Today is the first time i 'saw' it exactly, but there is no explanation, no logical reason for it to happen. No button i clicked or even hovered over, afaik.
I have the speed options turned off.
Can you tell me what it is?
ty ;#)
... oh, i just got it, the middle speed button changes with the mouse wheel if you hover on it. So i remove that button i guess. I thought it was just a 'normal speed' button. Can i change that? No scroll wheel activation would be great, ty.

my experience since I use it has improved, youtube has become more beautiful and more immersive, I approve
