Firefox Consumes the CPU

Okay we all heard or read the stories of the CPU going to 100 percent or certain applications like. iexplorer.exe, firefox.exe, svhost.exe ect consuming energy all the time.

I have been researching this cause I play on a certain online game site where I use either whatever browser with either kinds of java to play java gameapplet games. Well some games work find some will slow or almost freeze. I checked the Microsoft Website and manage to get a hotfix and got a link afer making a request for a the hotfix. Here is the email with some items removed.

It still hasn't fixed the primary problem of of the browsers which ever it is, but what it did do make it more easily run so your system doesn't crash or freeze. I think its worth installing this update. But you must go to Microsoft.com and do a search for KB Article Number(s): 890582. There it will give you a link to make the request to Microsoft for that Hot fix. Then you will get an email like above to download and install.

I hope this helps some of you, it did me, but still looking for the complete reason why the browsers hog so much memory.. I have a theory, but only a theory.. I reinstalled the factory software from my computer and upgraded it to XP SP it worked fine when It was clean of any updates. Firefox, Internet Explorer. Everything worked greats. The Automatic Updates came in then I was back with same problem..At least I reinstalled that hotfix not availble to the public helps a little.

Bottom line up front: use NoScript. I must say that this problem doesn't come up that often for me, but it's a pain when it does.
The hassle with NoScript is that you have to allow for scripts to be run for each site. A pain in the beginning, but less so as time goes by (sort of like Zone Alarm firewall).

I support James R.Hall. Use NoScript and the problems do not appear. Had the same problem with Firefox even with latest versions which has now gone using NoScript.

EDITOR'S NOTE: No argument there... if you disable the function that contains the flaw, you won't be affected by it.

I suspect these cpu and memory problems of Firefox and other browsers and programs are not due to any one problem but to a confluence of several problems, and I could elaborate on each of the issues... but they all have one thing in common: Windows. Are any of the above complaints from anyone running Linux or BSD Unix? I think not. The problem is with the shoddy way Windows is implemented: they rolled their own tasking (non-preemptive) and virtual memory, and they were amateurs suffering from NIH syndrome (Not Invented Here syndrome) - they insist on doing things their own crappy way, ignoring decades of operating system research and experience. The result is a staggeringly bad operating system which most of us are unfortunately dependent on. And it's known to have memory leakage issues. And horrendous security issues (when the Chinese military broke into the DOD network and accessed the email of the Secretary of Defense recently, I'll bet you dollars to donuts the SecDef was running Windows).

And please, don't give me any crap about the superiority of Macs. I've done development on Apples and Macs pre-BSD, and it was just as crappy, just done differently.

And I'm not giving solid gold marks to the Linux and Unix weenies either. Part of the problem (I suspect) with Firefox and Thunderbird and their ilk is that their developers develop them on Linux/Unix platforms and are _extremely_ sloppy with their tasking and memory usage. Which you can get away with on Linux/Unix because the tasking (pre-emptive) and virtual memory are implemented correctly, unlike Windows, and cover up sins of programming sloth. On Windows however, the result is, when sloppy programming meets crappy operating system you get periodic and random catastrophes. Which is what we're seeing with Firefox.

Either Mozilla has to tune its crap better for Windows, or Windows has to improve. I ain't placin' any bets either way.

Now if only Linux (any version, please, Ubuntu, PCLinux, Knoppix, any of them, please) would just become as usable a platform as Windows, we could all get off Windows and start getting some real work done.

EDITOR'S NOTE: Interesting, but I just read an article today titled: "Fix Firefox's memory problems, says Mozilla director"

See http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9046561&pageNumber=1

I am having the CPU drag and slow-motion browsing experience whenever I bring up certain websites with videos (like youtube) and foreign language fonts (www.eenadu.net).

I am having this problem across different browers (IE, Firefox and Opera). My machine is XP Pro SP2 with 2 GIG ram. It's such a crapy "internet" experience just around the time people are talking about IP TV :) My next door neighbour just bought a new laptop having no luck with this issue on her old laptop.

EDITOR'S NOTE: It's perhaps a function of your Internet service provider. Does trying at a different time of day help? If not, consider upgrading your video card.

Firefox 2 has started to do this on my PC now. Firefox v2.0.0.11. Windows XP Pro SP2. All I have to do is fire up Firefox 2 with a blank startup page, then wait a few minutes. Suddenly the Firefox.exe goes from 0 to 99% CPU and stays there. If I close Firefox, the window closes but the process remains in task manager - have to kill the process. Happens with Firefox in safe mode with no addons as well. Mystified.

Have found solution to my problem. Might work for other Firefox 2 users. In tools > options > security. Untick the 'tell me if the site i am visiting is a suspected forgery'. box. CPU use went from 99% to 0% once I had done this (had to restart firefox first though). This article might be usefull http://weblogs.mozillazine.org/asa/archives/2007/11/firefox_3_beta_1.html

I have Windows XP Home SP2 and Firefox version 2.0.0.11. I have had this problem with Firefox as well. Every once in a while, Firefox will spontaneously jump to 99% CPU. However, it gets a bit tricky after this. After I end firefox.exe from the Task Manager (b/c clicking the close button won't work) my CPU goes back to idle. But when I click on any other window, THAT application suddenly jumps to 99%. If I end that one, the same thing happens with the next application/window I click. This keeps cascading until my system locks up, and I have to do a hard shut-down.

If I then re-boot and log back in, my computer hangs while it is logging in, and I have to hard shut-down again. The only way I've to restore functionality is to boot in safe mode and use System Restore to the latest point before the incident. After that, everything works fine. This whole process has happened to me three times since upgrading to Firefox 2. Anyone have any ideas?

Thank you Alan, your solution worked for me also

I had the same problem. Quite a lot of plugin in firefox, not few tabs open. I am browsing in Chinese website with a lot of ad and heavy (not to mention useless) content. Result : CPU 95% just for Firefox. I tried the plugin NOSCRIPT and Firefox jumped back to a reasonnable 0%. Thank you NoScript!!
