EN: YouTube module perfect and very sober.

Amazing extension. It changed my life when using Youtube, there are all the functionalities we needed. It could be really cool te bo able to change the moment when the player minimize himself.

Très bon Module qui permet de profiter pleinement de Youtube. Je recommande !

I am glad the official successor to YouTube+ is out now, and it's defiantly living up to it's legacy!

Excellent addon. If you like to watch youtube on firefox browser this is a must have addon.

I had to stick to YouTube's older layout for a while 'cause YT + was incompatible with the then-new layout. I say this upgraded add-on was worth the wait.

Can't use YouTube without it.

Been using this script/addon since it was called YouTube + and tried many others like it like YouTube Center and various other userscripts. This one is unobtrusive, does what it needs to efficiently and gets out the way. Great way to set default video quality, video size, works with YouTube's dark theme, set your YouTube homepage to some other page (I choose subscriptions page), reverse video playlist order, disable comments if you want, and a floating video player as you scroll down the page, among many other features!! The only thing missing that Youtube+ had that Iridium doesn't have yet is being able to resize the floating video player when you scroll down pages. Please add that!

Best addon by far as particle. Good work man!

By far the best Youtube enhancer add-on. I highly recommend it!
