Hey guys, recently my MacBook has been running very loud when i only have like, 2 applications open. This started maybe 3 days ago. The 2 applications were iTunes and Firefox. on iTunes i just play music and on Firefox im on Youtube or RuneScape. It's been running fine ever since i bought it just over an year ago (playing the same applications) but now its started to get loud when i use it. Heres my Activity Monitor when i had RuneScape/iTunes on:

The fans are running loud you mean? Are they on all the time? Firefox is using a lot of cpu in that pic.

Flash tends to use a lot of CPU cycles.

As you can see the CPU usage of firefox is quite high.

I can't think of anything it could be other than watching a lot of youtube videos honestly.

yeah i was talking about the fans being loud. is there anyway to fix it or make it stop? other than quit firefox.

Im not big on firefox but you could try clearing the history and cookies/cache see if that helps
