I am using IE8 at the moment for watching youtube vids which is fine but when i try to watch them in HD it take a long time to load even though my connection speed is good so i wanted to know what is the fastest browser for watching HD youtube videos?
Firefox would be a good choice
Not sure if HTML5 makes a difference when it comes to speed but...
YouTube - Broadcast Yourself.
...But I use FF still.
Tux is right, you're going to have more problems with the video plug-in then the browser itself.
I typically download HD videos before I watch them, streaming them can get too unreliable. I'd research alternative video plug-ins than the norm. If you can't find any, switching between browsers may be your only option if they all don't use the same one.
Well keeping in mind that Google bought Youtube and therefore owns it, I'd say Chrome is the best choice.
I personally don't like Chrome that much. Other browsers should work well enough too.
This is pretty much all down to the Flash plugin, which will be the same in each browser.
Make sure your flash is fully up to date.
Things should get better later this year. Flash 10.1 is supposed to be a big improvement.
You could track down a flash 10.1 beta and you may see performance improvements.
Do note that some youtube video seem to be on slower servers.
FWIW, I just verified identical performance between Firefox/Chrome on Alice HD movie trailer.
Both loaded at max bandwidth, and both played smooth as silk using about 16% CPU.
