Hi all

I have been experiencing high CPU usage (138%) on my MacBook, while looking at flash videos on the internet with the Firefox browser. Mostly this usage makes itself noticeable by the loud noise of the fans and a hot MacBook which is very annoying for me.

Does anyone know how to solve this problem or a workaround in of any kind?

138%??? ^^ anyway, flash playback is a very demanding task and high CPU usage is quite normal. IMHO flash is an outright pain in the behind. – Molly7244 Dec 27 at 1:00

You can try using a Flash Blocker (eg. FlashBlock for Firefox, ClickToFlash for Safari - loads the H.264 files using QuickTime instead!) to help alleviate the CPU spike caused by ads. However in terms of just the spike caused by using Flash, you can try upgrading to 10.1 (available at labs.adobe.com). However there isn't much alternative beyond Adobe improving the performance of their plug-in.

ClickToFlash is fantastic. In WebKit nightly it lets you watch videos in full screen without melting the CPU. – porneL Dec 27 at 13:59

Generally flash takes up that much CPU as a web browser plugin. Try saving the flash file and loading it in an external player.
