Well I downloaded Firefox today, after getting it yesterday, and the system is INCREDIBILY HOT when I use it.

When I use Safari, according to CoreDuoTemp, CPU Usage is at ~7% and at 53 centigrade.

When i use Firefox CPU Usage is always more than 45% even if Im not doing anything and the Temperature is 65+ centigrade.

Anyone else getting these type of problems?
 
I love FF (used it with Windows and Tiger), but it's prone to problems (hangs, crashes). I've encountered this on boths OSs.

I use either Safari or Camino. I like Camino better than FF.
 
ummm........ k.....



so do you have a macbook or pro? does it make your system hot?
 
sometimes...FF makes the cpu run very intense. this happens mostly on flash sites. don't know why is doing this, but i had the same problem on the PC.
 
I guess im going to stick with Safari until that problem is fixed. It never happened on my PB =/
 
Wow maybe it does and I never noticed until I read this thread.

In firefox when I hold the mouse button down anywhere on a webpage the CPU usage for core #2 shoots up to 60-100%, and when I release it the usage goes back down to its normal <20% level.

Any other macbook people having the same thing happen?

I have an MB. I haven't really used FF too much on my MB as it causes one too many hangs and crashes on my Mini. I stick with Camino and will sometimes rotate to Safari.

I'm not sure about the actual CPU usage, but I never noticed my MB running any warmer with FF than with Safari or Camino. The temps according to TempDuo read about the same.
 
odly enough I have noticed a similar issue on my desktop pc were loading a page in firefox with lots of images places a large load on the cpu.
btw I have an athlon xp chip. Quite posibly some sort of a bug firefox has with images and or heavy gfx sites.

It seems to me like firefox has been geting more buggier or resource hoging lately. Not good as I used to love firefox and now not so much :/
 
I use Firefox on my Macbook , no problems, cpu's are running around 67-69c.

White 1.83 2 gig ram
 
Yeah... turn off FireFox and you will see your CPU temp dip down to the 50s :eek:

Wow, I didn't know about this. It reports CPU usage at 99%. Thank goodness I use Camino & Safari, then. :)

EDIT: Whoops, typo.

It was fixed two months ago, should be in the newer version of Firefox.

It has been around since Netscape. Quite a few other carbon apps do it also.

I actually just noticed this today. Firefox is pounding on my Core Duo, even when it is apparently idel. I am also wonder if the Google synchro-extension has anything to do with this.

Very strange.

NB: My Firefox is the latest version.
 
I love Firefox, and much prefer it to Safari when browsing, but I have noticed that my Macbook's been getting very warm even with nothing going on. Never would have thought to check if it was FF being naughty. I began using it essentially as soon as I got the Macbook, so I haven't compared it to Safari with respect to CPU usage and heat generation.
 
Ironically I find that FF seems to use atleast 15% CPU usage even when it is doing nothing but sitting on Google's webpage and hits temperatures in the mid 60s Celcius. When I run the terminal command yes > /dev/null which utilizes one of the core 100% (50% for the entire system) it also hits just in the mid 60s...
 
What's up with everybody's "Firefoxes", as long as I stay away from Flash-contents my Bon Echo (aka Firefox 2.0 alpha) stays between 1% and 2% when "idle" with a couple of tabs open and some animated gifs running on my MacBook. That's less than Activity Monitor:

Ok, this is more than Firefox 1.5.0.4 on my iBook G4, which idles well under 1%, but it's still nowhere near what you guys are talking about... :confused:

Seriously, get real! :rolleyes:

And get Flashblock! ;)

Firefox version 1.5.0.4 on PowerPC holding the mouse button (why would someone do this anyway?) produces at maximum 2 % CPU usage.
