As far as Firefox goes, this is an excellent user script. 5 stars!

Unfortunately, it doesn't work at all in my primary browser, Opera. I won't retract points for that, as most user scripts are designed to work with Greasemonkey and/or Stylish and don't take Opera's native user script capabilities in mind. I do suggest you look into it, though. There are many Opera users that would be very glad to not need the terrible Flash plugin to watch YouTube videos.

I used this script for ages and it worked great. However, it no longer seems to work. I think YouTube changed the format of the page. Instead, I'm now using this script which works beautifully:

Only thing I'd wish for was loading the youtube srt subtitles into the video.

Thankyou! This doesn't work on my Ubuntu 10.10 system (FF 3.6.10) when trying to use the VLC plugin, but it works excellent with the Totem (Generic Player) option. This cuts my cpu usage dramatically, is faster, and can be popped out easily. Thank you for this excellent script!

The player allows my 8 year old
Pentium IV computer to use VLC
for smooth play without dropped
frames. This is what I have been
asking for at the SeaMonkey forum.

The player is missing controls for
sound volume, pause/play/stop and
has no full-screen capability,
though there are 2 size options.
It would be perfect if the
controls could be allowed and
full-screen.
Is this an issue for VLC instead?

Da quando i plugin di Totem non sono più in grado di accedere ai video di Youtube questo script si rivela essere il sostituto ideale.

Si fa apprezzare per la semplicità d'uso, il buon funzionamento e l'integrazione perfetta con il portale.

Ora è stato aggiunto anche il supporto ad Epiphany-browser, mostrando una marcia in più rispetto a script che svolgono un lavoro simile.

La soluzione migliore per Youtube!
Complimenti all'autore!

Perfect! Just want I need. Flash sucks, jk.

Works as it's supposed to. Finally can watch YT in full screen. Happyness.

I'm sure this is great if you know how it's supposed to work, but how it works is beyond me. There are a huge number of controls and options, but all I want is to be able to tell the browser to use something other than Flash, and it's not doing that. What are you supposed to do?

Gives much higher performance than viewing videos with flash!
