Firefox just pegged my CPU at 100%...
 

I was browsing CD, and I was reading this thread:
http://www.chiefdelphi.com/forums/sh...threadid=50665
and I noticed my fan turn on. That was really odd as that only happens when I am actually straining my computer. I've got a brand new Dell Latitude D520 laptop--that's a Centrino Duo 1.66ghz dual core. After looking in my system monitor program and the task manager, I noticed that my processor was pegged at 100% usage, and Firefox was using 96-99% processor time in Windows task manager. I closed it in desperation--this was freaking me out. It went away and left the processor idle again, and I am happily browsing like normal once again. I am wondering, have any of you Firefox users seen anything like this? A quick Google suggested that the Flash plugin might be causing this, but I didn't see any flash content on the page I had open.

At first I had suspected my anti-virus, but that's not what task manager said.

I'm confused. And there are no updates available from Mozilla, so they either haven't seen this problem or don't have a fix yet.

I hate it when I break stuff.

Just curious as to whether or not you've seen this type of behavior in FF. FF2 has given me other troubles, too--the "grey window of death" I call it, I will post a screenshot when it does it again. I just hope that things pull together and FF goes back to its seemingly bug-free self.

Attached are two pics, the first (start_CPU_peg.jpg) is what my system monitor recorded the processor usage at when the peg started. It looks like it pegged one core, then started another thread that pegged the other. The other pic is end_CPU_peg.jpg, when I closed FF about 30 seconds later and the processor usage went back to normal.

Its a quite well-known phenomena to have memory leaks in Firefox. Mozilla knows it exists and is trying to find a way to fix it. They haven't yet.

Re: Firefox just pegged my CPU at 100%...
 

Hmm. It didn't look like a memory leak to me. firefox.exe was taking up about 26MB of my 1gig of RAM, so I would guess that's not what was going on.

I don't know though.

I will go you one better than that. Running Lightwave on my computer seems to have allowed it to defy certain laws of physics. See the image below. I am running a Dual 3.00GHz Dual-Core Intel Xeon Macintosh Pro (ie. four processors). With all four processors maxed out, I should be running at 400% CPU utilization (4 processors running at 100% utilization). But this software is SOOOO amazingly cool that I can actually get an extra 8% out of each processor! Apparently, the software included a little known "wormhole feature" that allows the computer to suck extra unused cycles away from other dimensions and transport them here for my use. I knew this new computer was good, but this is a level of service that I never expected! :)

DROOL!:eek:
Cool! I want a mac! (NOT!)

Or a PC with 4 3GHz processors...whoo, that would make one *hot* laptop, in more ways than one...:yikes:

The shirt is black...... NOT.
I want a mac..... NOT.


Coincidence? I think...... NOT.

Re: Firefox just pegged my CPU at 100%...
 

I don't know about 100% CPU usage, but I've been having other problems with Firefox. Half the time I start it up, it comes up with a message saying that there is a problem with the flash player and recommends closing firefox. Regardless of whether I close it or not (since eventually it just ceases to function), when I try to re-open it, it says that there is already an instance of Firefox running, and won't allow it to open another window. I either have to close Firefox through the task manager, or restart windows. This has been happening for over a month now, and even though we recently updated both Firefox and the Flash player, it still has this problem.

Any ideas why?

I'm sitting here with a 3ghz P4 w/HT laptop thinking its getting hot, but I don't think I could even be near something like that! :D

I've been using Firefox for about a year now, and I've never had any problems when I didn't have a beta version. FF2 had some issues, but I haven't had any problems since the last update, except for memory leak.

Go to this link http://www.computertalkwithtab.com/ click on fourms and post your questions. These guys are great. You can also listen to their show live on the internet most Saturday mornings by going to www.wtic.com (seems to work better with IE right know) click on listen live they are on from 10am to 12 noon eastern.

I was having problems with Firefox yesterday with Yahoo Pool. Every time a game would start, it would crash.

Don't be jealous of the awesomeness of Macs!

EDIT:Wow, Firefox has awesomeness in the dictionary! That is cool!

Re: Firefox just pegged my CPU at 100%...
 

Umm...what am I missing here? Where did the first line come from?:confused:

I saw more forum threads regarding how FF interacts with the flash player than I can count. I would guess it's one of those things where you need luck to get it going (the other one of those I know about is USB to Serial drivers...but that's a story for another day). Google it and you'll see what I mean.

I was thinking about posting on the Tech Support Guy forums, too. I think I'll do that.

Yahoo *Pool*? Seriously? That's almost as lame as an NFL sim game...:D

EDIT:*I was joking! Don't kill me! Please have mercy*

I get every one of those problems, but not that often. I don't know why. Have you tried completely uninstalling Firefox and installing again, instead of just updating it?

Dave's Mac computer is rendering the 2007 FRC game animation. :D

P.S. The number of Macs owned by Team 228 has outnumbered the number of Window PCs we own by nearly 3:1 for the past nine years.

Just to answer your question as a PC user since 8086 2MHz. The new Apple computers run on Core Duo Intel CPU's so they are as much a PC (x86) as any other. They just come with a different OS and WMI BIOS. These machines can dual boot into Windows XP/Vista run like a normal PC except the single mouse button. Also, OSX is a port of BSD which is unix based and can control devices on alot lower level than you can in an NT based OS like 2000 / XP. After having used windows forever I really like the feel of OSX its easy to buzz around in. There are alot of good freeware OSX apps and it can run all the freeware windows apps in wine, plus all the freeware unix apps.

I just ordered a SIIG 3/4 Cardexpress to RS232 it should be just as fast as a onboard UART. Apples don't have serial ports but neither does most of the laptops and desktops you would purchase today.

Everyone has a right to their own opinion, buying an Apple today is more like just buying a Dell or an HP. Where when they were using PowerPC, it was more of a commitment to a lifestyle.

I didn't realize firefox had these bugs... Well, IMO it's still way better than IE7.

<tangent>
I drool over what macs can do with video editing... the ease of use, and speed. Really its just because its built in to the OS. I still envy you Dave.
