Flash slowing my pc
You may have noticed your PC slowing down. I did a little bit of monitoring today and the problem - for me at least - is the countless and mostly unnecessary adverts and flash movies. eg sites like the BBC - that clock on the top right uses 10% of my CPU.
Fortunately there is an add-on for Firefox 2 and 3 which turns off flash movies until you want to play them.
Use Tools - Add-ons - click get extensions and search for flashblock then click add to firefox.
