I've noticed recently that sometimes if I have over 10 tabs open in Firefox my fans speed up to 5000RPM. I check Activity Monitor and CPU for Firefox is at 100%. Even if I close all tabs except for one, fans will run high and CPU will remain 100% until I close Firefox. Besides this, opening the Application folder is pretty slow, takes 10 seconds to display. I've done repair disk permissions, but perhaps I should try Techtool Pro as well. Anyone else have any suggestions?

Thanks!

I think what you're experiencing is normal. Ten windows open in Firefox takes a lot of GPU and CPU power thereby generating heat. The fans ramp up until the temperature comes down. Closing Firefox releases the CPU.

As far as applications opening slowly, how much system memory do you have and how much hard drive free space is available?

Download the free "OnyX" maintenance program from here and run it.

Regards.

I generally run 10+ tabs in Firefox 3.1 beta and haven't had this issue. My guess is that one of your add-ons is having some issues. I would recommend removing all add-ons, testing, and if the problem doesn't persist, add each one back in (one at a time) and see if you can narrow down which one is causing it.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Actually I'm probably running closer to 30+ tabs :-p But only recently the fans just ramp up all of a sudden and CPU hits 100%.

I used Onyx and I think my system is snappier now. I also reinstalled Firefox and I think that helps. I have an add-on extension called "Look up in dictionary" and "Print-it!" which I hacked to work with Firefox 3 and beyond. For plug-in's I have Flip4Mac v2.1, Google Update 1 Click Deluxe Installer, Java Embedding v0.9.6.4, Quicktime v7.6, Shockwave Flash v9.0, Silverlight v2.0.3, and Speed Download.

Hacked plug-ins would be the first thing I'd pull to test.
