Firefox 3.6.10 dominating cpu resources

I have a Intel Pentium 750MHz computer running Win2000 Pro with 512 Ram.
Before I updated Firefox to 3.6.10, I could run Firefox and/or have more than 1 internet window open.
Now, Firefox runs 95-99% CPU utilization, thus slowing everything down.
Can I return to a prior version of Firefox?????

Firefox consumes a lot of CPU resources after some time

Hi,
I've upgraded from Firefox 3.5.16 to Firefox 5.0 on Linux i386 with 512 MB RAM. Everything is working fine until after "some time" (don't know the exact time period) the CPU load increases to 100%, my average system load explodes and the system is swapping memory wildly. This suddenly happens, even if Firefox is in the background while I'm working on different things. So it does not belong to any memory-hungry stuff like Flash pages or JavaScript sites.
I don't think the problem is caused by my extensions (adblock, noscript, multifox, tabloc) or plugins (mplayer/Flash) either.
I think it is the Javascript Garbage Collector. I could tweak its cycle time in about:config, but this would just be work around the problem.
Note that I usually have many open (app) tabs that extensively use Javascript and AJAX.
I really like the new Firefox features, but I haven't expected that "5.0" stands for 5.0 average system load. Sorry couldn't resist that remark ;D

I updated to Firefox Aurora this morning. Problems seem to be solved. Thank you!

Firefox is repeatedly overloading my CPU

My problems with high CPU usage by Firefox started a few weeks ago. Here are the fixes I've tried so far:
quitting firefox and opening new browser window: helps briefly, but screen freezes start again within a minute or two, sometimes right away
restarting computer: doesn't help any more than quitting and restarting firefox
clearing cache and history: did not help (have done this repeatedly)
disabling extensions: did not help
updating firefox again: did not help
uninstalling firefox, removing all hidden folders, clean reinstall: seemed to fix problem initially, but after a few days, I'm right back where I started
running firefox --debug with gdb installed: gdb found no debugging symbols
turning off chat in Facebook: did not help
I am currently running Firefox 10.0.2 with Linux Mint 9 (Isadora). My configuration is x86_64-linux-gnu. I generally keep browser tabs open for email, Words with Friends (my only regular use of Facebook) and Ravelry, with one or two other tabs open as needed for other tasks.
Possibly useful information from my system information summary:
Processor : 4x Intel(R) Core(TM) i3 CPU, 550 @ 3.20GHz
Memory: 5922MB (1268MB used)
Since the clean re-install of Firefox, I have only added one extension (Add to Search Bar 2.0) and re-imported my bookmarks list. The other extension and add-ons (which I presume came with the install) include Ubuntu Firefox Modifications 0.9.3, IcedTea Web Browser NPR Plugin, iTunes application detector, and Shockwave Flash 11.1 r102. Just for grins, I tried disabling them all again, and it made no difference. All system updates are current. I've been keeping my system monitor open and each time my browser freezes, I'm seeing 100% CPU usage by Firefox (actually, as high as 120%, although I don't know how that is possible).
Any other suggestions? I'm really motivated to keep using Firefox, but I'm not sure what else to try.
Thanks.

I am not sure I can help much here, but obviously the spec of your machine exceeds the requirements, and so I would not expect such high CPU use.
I realise malware is probably not a big problem in linux, but as you notice no problems on a clean re-install
clean reinstall: seemed to fix problem initially, but after a few days, I'm right back where I started
and have tried to rule out other causes maybe you should also consider a possibility of a malware problem.

While being idle online for a few minutes, why does Firefox start cyclically using 50% to 5% CPU resources, with a 10 to 1, hi to lo ratio

This behavior became apparent after the last couple of Firefox version updates. Current Firefox version is 21.0. My PC is an IBM ThinkCentre running @ 3.0 Ghz Intel CPU with 1.5 Gigs PC3200 DDR ram. With or without any other Windows apps open, whether I'm on line just idling on my home page (Google) or any other web page or entering / receiving data, several minutes into a session, the MS XP pro SP3 task manager shows Firefox cyclically using 50% (and more) CPU resources for 8-10 seconds then 1-5% CPU resources for 1-2 seconds. Closing & restarting Firefox, allows me a few minutes of speedy surfing. My ISP is AT&T 2nd tier DSL with a download thruput of 300 (+) MB (not Mb) / second (altho, most of the time I'm just viewing a web page or idling, without downloading or uploading any data).
What has changed? My PC & all of its software have remained the same with the exception of MS security updates, Adobe Reader updates, & Firefox updates (without adding any additional plug ins, add ons, etc., with each update).
What the...! For the past several minutes that I've been inputting data here, the task manager showed a jump of only 13% cpu usage (ever so briefly) by Firefox & only then when I switched between the task manager & Firefox. Intermittent anomalies are gonna be the death of me...
Well, this is an annoyance, albeit an intermittent one. Ah, I pine for the days when I heard about & believed in "seamless integration"...any thots that might help resolve this issue sure would be appreciated.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Firefox using massive CPU resources, even with no addons?

I've been trying to figure out why Firefox is using ridiculously large amounts of CPU resources, but can't seem to find anything. At the time of writing this, I have 5 tabs open, none of which are highly graphic- or sound-intensive (facebook, 3 articles and this) and no add-on toolbars running. I updated to FF7 the other day, primarily because FF wouldn't open without doing so, and it's currently using a little over 625K in CPU.
I've tried restarting, but it starts at around 105K and skyrockets to around 300K within 5 minutes and I can't think what to do to sort it out. I've tried running it in safe mode, but there's no difference to the CPU usage. Add to that the fact that I can't even run another program at the same time (making me choose between music or internet), and frankly, it's driving me up the wall.
I don't want to change browsers, for the simple reason that I prefer FF in terms of usability and appearance, so I'd prefer a fix if possible. The troubleshooting information included is from my current session, which does have some addons re-enabled, since disabling them did no good whatsoever.

Firefox sometimes freezes up for a few minutes and begins using 47% of cpu resources and sometimes also extra 100-200kb of memory

since updating from 3.6.xx to firefox 5, 6 and now 7, firefox sometimes will freeze while loading a site and use 42-50% of cpu resource. it also sometimes doubles or trebles memory it uses at same time as freezing, and freezes for 2 or more minutes. when it comes back sometimes it will have failed to load a page and will display the url but a white screen. this can happen any site, but seems to occur more when on image sites. usually i have more than one ff window open, one of which is an iboard, and the freezing seems to occur more often when either posting, or when opening a subboard or more often a thread in tabs or new windows. problem seemed to be helped when i disabled a recently installed java plugin but didnt disappear, and it can still happen anytime with only one window/tab open. the only common thing seems to be the site is either refreshing, or loading.

Firefox 3.6.24 is stressing memory and CPU resources to the point that Hotmail is almost unusuable and computer jams while FF goes thru its athletics; what to do?

I have a Dell Inspiron 710m, with Windows XP, Norton 360, IE8. My computer understanding and needs are simple. Norton lets me know that Firefox is eating memory and CPU. The machine often jams while this happens, whether or not Norton has flagged an operation, and then resumes function. Hotmail is in shambles (jamming between operations, and having sign out problem). Neither Norton nor CC Cleaner (including Registry) indicate a problem. This is a nifty little machine that I use for email, mostly newspaper subscriptions, online shopping and banking, personal, and for Internet research. I have tried more advanced versions of Firefox and found them buggy. So, I went back. The upgrades are coming too fast. Not everyone is going to invest in another machine for Windows 7 or IE 9 capability right away. Meanwhile, Firefox, which worked just fine, seems to be pushing along, in what seems to be an industry in which cooperation and compatibility have ceased to be important. I don't know what to do. I can't do complex diagnostics and fixes, and am not in an area where I would take this computer anywhere.

Thank you for taking the time out to reply. I don't know whether or not your suggestions would have worked, but I did solve my problem. I eventually figured out that the file, overlay.xul, was doing something and when I changed the filename, the bar went away.
I was reading that the xul error usually meant something wrong with an extension, but that didn't make sense because after uninstalling/reinstalling, there were no extensions present, on an assumption, of course. I noticed a file through a search, and it was located in a folder without a mozilla/firefox name in it, looked like a randomly generated folder name. I looked in the extensions. ini and noticed it pointed to that overlay.xul file in that random named folder and thought, what the hell, and just renamed the overlay.xul file to something else and the problem went away.
Thanks again.

X61s Hardware Interrupt up to 40% of CPU resource

Hello, i recently updated my harddrive of my x61s to a seagate Momentus ST9320421ASG 7200.3 GForce - 320GB 7200rpm 16MB. After that i have done fresh Installation with Windows XP Professional on the new drive twice!! Each time when i finish installation i begin to get a wired Hardware Interrupt with constantly eats up to 40% of my cpu resource and cuts my battery life to half. i have tried to deactived the component one after another in order to locate the problem(which componet is sending the interrupt). But i found nothing. And the interrupt does not start right away when i boot into XP. it starts sometimes later after login or start some programms like opera or Firefox browser. Does anyone has an idea about this issue? BTW, i already use the system update to get all my drivers and bios to the newst version. Thanks!
Solved!
Go to Solution.

T his issue annoyed me for a long time , but final!! eventually !!! i fixed it!
its because of the latest intel display dirver.
so everyone just need to download an older one.

[Solved] embedded videos in firefox take a lot of CPU time

Playing embeded videos in Firefox take a lot of CPU time. Actually my old computer is not able to play these videos correctly if they are in HD. The problem appears with flash videos (not so surprising, flash sucks...) but also with html5 videos (there is an option in youtube to turn that on). However if I succeed to have the direct URL, these videos play perfecrtlky fine in mplayer using not more than 10-20% of CPU time. Is there a solution to that? Is there any possibility to use an external player to play HTML5 videos in firefox? If anybody knows, Why this problem, are the mozilla folk aware of this problem? (Note that I posted a thread a long time ago for this problem but concerning flash only)
Last edited by olive (2012-04-27 20:33:59)

There's not much you can do to make HTML5 videos as fast as Xv, see http://swfdec.freedesktop.org/wiki/FAQ. They are slow for the same basic reason as Flash... the video overlay cannot be used because the standard allows for controls and CSS to be rendered on top of the video.
As for redirecting to an external player... this is not as easy as it could be. If the videos appeared in <embed> tags or <object> tags, one could use Mozplugger, Media Player Connectivity and other programs, but I don't think one has been written to handle the <video> tag. An upcoming update to firefox will make it use gstreamer, however. If this still results in slow playback, it will at least make it easier to use an external player. I imagine you would have to patch firefox to make it use a port on the localhost as the video sink instead of the screen. Then you would run gst-launch to receive that RTP stream.

Firefox causes surge on MacBook CPU

hi:
this problem been going on for at least 3 months so it is cross version of Firefox as I've updated recently to 17.
after a while, I think it's 1.5-2hr if I've been surfing .. doing stuff on MacBook.. andcfirefox been open entire time
I hear the CPU do a surge and stay at it this higher CPU.
last night I worked out it was purely Firefox. I closed Firefox down and within 1-2min.. CPU was back to normal. no heavy sound of processing
my MacBook Pro is only 1 year old. so it's app issue not hardware.
last night I retested this three times
first time / only Firefox open
second time / Firefox and Opera
third time / Firefox / opera and mail
all three times when closed Firefox CPU went back to normal.
tonight I will turn off all addons to double check they are not cause. I think I've did that and still CPU usage surge. but will double check to be absolutely sure.
Firefox I use extensively
I have
1 one window with 15 tabs for stuff I'm researching and currently working on
each tab is simple site eg amazon book page
2 another window with my ACTION tabs. typically 4-5 open
"so my question is"
1 what is suggested troubleshoot steps to work out which part of the Firefox solution is causing my CPU usage
2 what are common things to check with CPU surges?
thankyou in advance

many thanks
for quick glance - i have none of the "baddies"
will go thru article very methodically...
i notice the CPU goes up to 500 regularly.
today i ha activity monitor showing to see how often it surged
5 times in 1 day

Make sure that you do not run Firefox in compatibility mode.<br />
You can open the Properties via the right-click context menu of the Firefox desktop shortcut and check that in the "Compatibility" tab.<br />
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.<br />

SQL Developer occasionally hogs all CPU resources

I have noticed this happening occasionally when I :
1. hit Enter at the SQL Worksheet window
2. hit F9 at the SQL Worksheet window - the query does not start

Who can I send the information to ?

How do I collect a dump or some kind of debug

Cpu resource is available but many run-queue from vmstat

Hi, all
I coundn't find appropriate category for this system related questions.
I am sorry for this.
The system has more than 100 CPUs on a linux machine, but there are more than 10 run queues.
As you see, "r" is around 10, but "id" of cpu is about 90%.
=> I cound not understand why processes do not use OTHER available CPU resource in stead of waiting in run-queue.

Thanks for your reply.
"r" is the number of processes ON CPU plus the number of processes WAITING FOR CPU.
The following is from "man vmstat".
Procs
       r: The number of processes waiting for run time.
       b: The number of processes in uninterruptible sleep.I am confused whether or not "r" contains processes which are corrently on cpu, not in run queue.
Could you give me more detailed explaination or some article?
Thanks.
Best Regards.

X200 Hardware Interrupts constantly at 40% of CPU resources

As many other thinkpad owners I started to experience excessive "Hardware Interrupts" using between 40-45% of my CPU resources (on both cores) on my x200. Note that Task Manager will _not_ show this, you will need something like Microsoft's "Process Explorer" to show this. This started about a week ago, following a slew of updates I had been rolling in from "System Update" on my Vista x64 Business.
I searched the Internet high and low and found many similar experiences (not only with Lenovo models, not only with Vista). Obviously, it is nearly impossible to find out what's causing this. There is a useful tool called "KrView" by Microsoft that will display more info about which driver is causing the interrupts, but unfortunately it does not run under Vista x64.There is also an on-board Vista tool that allows you to check for unsigned drivers but that didn't seem to be the problem (all drivers were certified ok).
Other have reported problems with their network drivers where such interrupts would occur as soon as they turn on WiFi. Some were successful by removing their installation of Deamon Tools (which I have not installed, so that didn't help).Others suggested hard disk drivers or CD-ROM driver issues.
I thus tried to home in on the probably culprit, and found the following puzzling effect: This only occurs when my x200 is in the docking station! After a clean startup, it will be nice and idle for some time, but after some 5 minutes it will start to constantly show the 40-45% of "Hardware Interrupts." Once this happens, it almost never goes back down, even if you undock it. However, if you _start_ the system in an undocked state, the "Hardware Interrupts" do not appear!! I even tried to manually connect all the different pieces that I have attached to my docking station one by one to my undocked laptop (e.g., network cable, external keyboard and mouse, USB harddisk) - none did trigger this. But as soon as you redock your laptop, it will spike up again to its 40-50% "Hardware Interrupts".
I _assume_ that it might be the display driver that causes this, as this is the only piece of hardware that I couldn't "test" on my standalone laptop: I use a displayport cable to connect by 24" monitor, and the x200 does not have a connector for this... I tried installing the latest Intel graphics drivers but the won't install and tell me that I must use the OEM lenovo versions. I also could not "rollback" the driver (option greyed out) and the old driver version doesn't seem to be available on the lenovo post...
Alternatively, it might be some sort of "docking station driver" that's causing this. Although I'm not sure what this driver would be and how to update it :-(
Any hints? (sorry, ultra-long post)

And this is the kernrate log after I uninstalled the sata controller from control panel. No CPU load.
I restarted the machine after removing the sata controller and it installed the controller again, it has prompted me to reboot again to finish the installation but I haven't done that yet. Until now, no high load has happened.

Moble device support uses 50 percent of cpu resource

I tried uninstalling Itunes and all of it's components. I have a pentium 4 with 3 gigs of ram. Apple Mobile Device Support uses 50% of CPU resources and slows my computer to a craw when Itunes is not running. I don't mind if it uses resources when using the product, but it uses the resources even when your not running any Apple software... Windows XP 32 bit pro all service packs and upgrades. Itunes 10.5 or latest. Any help please..

I am having same problem. Many say reload iTunes in a particular way. Some say that works, others say it doesn't. You can run "netsh winsock reset" and it will temporarily free up the memory once you reboot, but it impacted my IE from finding the server. Still looking. Apple must know this is a problem. As one use said, have they heard of regression testing?

Firefox 3.6.10 dominating cpu resources
