How to make Youtube less CPU-intensive?

[Pawnless Endgame]

Due to unforeseen circumstances, I'm currently working with a 2007-spec laptop.

It'll play no probs:

- 1080p BBC iPlayer
- 1080p MP4s, FLVs, AVIs etc
- 1080p SWFs

Hell, it even plays blu-rays using an external drive without stuttering!

Youtube, however, just cains the CPU, forcing me to download the videos to a local drive, then play ok in Media Player Classic. Any idea on how to make Youtube 'lighter' considering that iPlayer / blu-rays play without interruptions?

Thanks! I forgot that Youtube now uses HTML5 instead of Flash, which explains why Flash etc is still ok on my lappy. Indeed the GPU is just onboard Intel fluff

The pre-installed Internet Exploder 7 gave me surprisingly good results (!), so thanks again guys. Will stick with Firefox 39 for everything else though.
