Firefox is using up all my CPU thus slowing my computer: add-on? or malware?

My computer has slowed way down mostly because of Firefox. I suspect an add-on, malware, or corrupt file in Firefox. CPU usage is 90-100%.

I am experiencing the same issue when ever I add a Genera iTune Pinwheels and starts using up all of my system memory. I took my computer to the apple store and they found that I had a bad Ram module. I will see if the issue persist after the new ram module come in. I hope it will fix the issue if not I will have to try uninstalling and reinstalling iTunes. What software are you using to copy the DVD I wonder if it is the software we are using to get the DVD to the Mac.

Firefox sometimes grabs 50% of my CPU, which slows my computer. Any suggestions for fixing this?

It usually seems to occur when I'm trying to get into a secure account (my 401k) or download something, but not always. Sometimes it just seems to occur when I've been on-line for awhile. I just downloaded Firefox v3.6.

That is exactly what I just experienced. Firefox is open on one tab, google search has just been run so nothing should be going on but 50% of CPU is sucked up doing who knows what.
Occasionally when I'm typing in, there is not echo back for several seconds. This sucking up 50% of the CPU goes on over and over again. 50% is the tops but you can't do anything at that point.

Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

Repeating Call Library Function Node uses up all my CPU

Hi,
I'm not very proficient at labview or programming so any help would be gladly appreciated.
I bought a USB Digital Input/output hobby kit (one of those things you build yourself). I have got it made and i have managed to get labview talking to it. It was supplied with a .dll to control it and the digital output works a treat.
However, i want to monitor the ditital input channels (as fast as possible), but if i get a vi to repeatedly call the dll then all my CPU usage goes with it. I don't really understand what the dll does and how exactly labview interacts with it. Can i monitor the digital input channels without using up all my resources?
I wasn't able to attach the dll that i'm using so i renamed it .jpg instead. You can rename it to .dll to look at it if you want.
Thanks

By putting a small wait (of a few milliseconds) you can decrease CPU usage without affecting your performance too badly. However, it really depends on how long a single call to your DLL actually takes. Have you measured this? If it takes, say, a half-second for a single DLL call to execute, then small delays are not going to help because the bulk of the CPU usage is taken up by your DLL.
By the way, a CIN is not likely to help at all. There's not much difference in terms of overhead for a CIN vs Call Library node anyway.

Since downloaded the last update, Firefox uses 90% of my CPU power slowing my pc to a crawl, why?

I switch on my pc and open Firefox and then the whole pc slows down to a total crawl, the page i am trying to open will take about 5 minutes to open. I try to close Frirefox but the whole program freezes and I have to force close it, sometimes I have to shut down the entire computer and start again. When I open task manager to see if there are other things running in the background it shows Firefox as using up a whopping 90-99% of my cpu power. If I wait for up to 20 minutes from when I first turn on my pc the problem seems to go away. But there are no other programs running on the machine to make it so slow. Not sure if this is the usual crap I have to deal with for running Vista or if its something to do with your latest update, I had no problems until after I had the update.

Firefox sometimes uses a lot of memory and slows down my computer, can this be prevented ? I am running Windows XP.

I sometimes get a message that Firefox is using a large amount of memory.

"Installer" using up all my memory and slowing macbook down

"Installer" seems to take up all my memory and slow my macbook right down, anyone know a solution?
Also the "18.68MB" is from the memory clean app showing how much ram is free, Installer seems to just eat it up

There is some adware called Genieo that often comes packaged in installers named "Installer." If you have installed that, you need to force the installer to quit, delete the installer and then follow the Genieo removal instructions here:
http://www.thesafemac.com/arg-genieo/
I would also note that I see µTorrent in your Activity Monitor. Be aware that downloading illegal material through torrents (or other means) is very dangerous behavior, and there has been a significant upsurge recently in adware infections coming through such files. Even a few malware infections as well. Do not download such things.

Firefox.exe* uses large amount of cpu 40-50%

My computer slows and task manager shows firefox.exe* very large cpu usage.

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

A patient is assigned an ednum. There are two different menus for staff to enter
diagnoses. Each menu stores the entries in a different table. The two tables are substance and pdiagnose. A patient’s diagnosis for a substance abuse can be entered in one table and not the other.
The number of entries for different substances for each patient can vary between the two tables. John Doe might be entered for alcohol and caffeine abuse in the pdiagnosis table and entered only for caffeine abuse in the substance table. They are only
linked by the ednum which has nothing to do with the diagnosis/substance. The substance entered in one table is not linked to the substance entered in the other. A query will not put an entry for alcohol from the pdiagnosis table on the same row as an alcohol
entry from the substance table except by chance. That is the reason for the way the query is written.
The query accepts parameters for a Dr ID and a start and end date. It takes about 7 to 15 seconds to run. Hard coding the dates cuts it down to about a second.
I might be able to select directly from the union all query instead of having it separate. But then I’m not sure about the order by clauses using aliases.
Is there a way to rewrite the query to speed it up?
I did not design the tables or come up with the process of entering diagnoses. It can’t be changed at this time.
Please let me know if you notice any inconsistencies between the DDLs, data, and output. I did a lot of editing.
Thanks for any suggestions.

This is minimal polite behavior on SQL forums. You posted a total mess! Do you really have patients without names?? You really use a zero to fifty characters for a patient_nbr??? Give me an example. That is insane!
Your disaster has more NULLs than entire major corporate systems. Since you cannot change it, can you quit? I am serious. I have been employed in IT since 1965, and can see a meltdown.

ITunes uses almost 100% of CPU and slows PC down

Recently I decided to start using my iPod touch 4G again and downloaded the latest version of iTunes.
Upon launch, iTunes acts normally until about 4-5 minutes of being open (just in idle). It then happily proceeds to use up 100% of my CPU load and slows my entire PC down to a halt, even once I've closed it (iTunes).
I've tried re-installing it, downloading a different version, disconnecting from the internet, practically everything and yet the problem persists.
My PC specs are as follows:
Amd FX Piledriver 8-Core FX-8350 @ 4.0GHz
Powercolour HD7990 Devil 13
G-Skill 1866Mhz 16Gb memory
OCZ Vector 128Gb HDD / WD Caviar Green 3TB
So I can assure you, this is NOT hardware related.
I've tried the following method with no results.
1) Click Start and type "cmd" (without the quotes) DO NOT press enter or Ok yet.
2) Right click "cmd" in the search results at the top of the start menu and select "Run as Administrator".
3) In the command window, type "netsh" and press enter. (Without the quotes)
4) In the next prompt, type "winsock" and press enter. (Without the quotes)
5) In the next prompt, type "reset" and press enter. (Without the quotes)
6) Reboot the PC. (Do not skip this step)
I've also been through the list of conflicting software and have none of the mentioned.
I'm running Windows 7 with the latest updates.
I'm getting extremely frustrated now. ANY help would be appreciated.

Sorry. I did a search, and a lot of threads came up. The one I chose, I thought, explained WHY it happened.
Maybe you'd get answers more helpful to you, if you went throught the search results.
Sorry I wasn't of any assistance.

I upgraded to Firefox 4 and now all sites are very slow. I cant even watch youtube videos anymore. Is their a way I can downgrade back to what I had?

I was given an option to upgrade to Firefox 4, so I did. Ever since I have done this, Facebook is taking a very long time to load. All FB apps either take a few minutes to load or just dont load. I have tried to watch Youtube and the videos are taking longer to view. I have tried to watch videos and they keep skipping. I have tried to reload the page, restart my computer and even upgrade flash but I already have the updated version. I need to know if their is any way to downgrade back the the Fairfox version that I had.

Upgraded to Firefox4 too. Suddenly I started to notice that browsing pages in my webbrowser qaws horrible laggy and I was seriously wondering if my connection was acting up, yet everything non-browser related was working just fine.
I can't even watch music videos on youtube now, as it will only load up to a 3rd of the song and then just stop loading anything more untill I click on the bar on a spot it hasn't loaded, and then it will start from there untill it gets to a 'block' again.
In other words: totally unusable for me.
I tried uninstalling firefox4 and going back to the 3.6.17 version, but now the issues haunt me in that versino too. It's like firefox4 sunk its teeth into my system once, and then older versions won't work proper either :(
Seriously considering just getting a different browser to be able to actually BROWSE the web again >:(

TS1717 help help! itunes is using 100% of my cpu when i try to add music to my library.

i have done everything apple said to do and still have this prob. win xp sp 3 all is updated. who else has this prob. and how do i fix it for good?

Is the Enable Disk Use option ticked from under the iPod's Summary tab? If not, go ahead and check it. This should help keep your iPod mounted to your Mac as an external drive.
I assume you have tried another USB port as well to see if that makes a difference? Are any other USB devices also connected?

After I install firefox can I remove Internet Explorer? It slows my computer down.

I have been told I should get rid of the Internet Explorer and load Firefox...Can the Internet Explorer be uninstalled and still get online?

I would not remove the Internet Explorer as some programs hard code it's use to get information from the web. I know that Intuit does this for their software.

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 use 100% of one CPU (Mac)

I use last firefox (32) on MacOS X 10.6.8.
Sometime firefox start using 100% a one CPU, from that time the only way to stop it was to quit (it take severals seconds, sometime it hang). When it start i can close all windows, firefox continue using 100% CPU.
I follow standard instructions (update to lastest, disable plugins and extensions...) it do not work.
I not a configuration to reproduce the problem : keep iCloud mail open in one tab is the way to reproduce the problem sometime after a few minutes, sometime after some hours : but it also happend sometime with no iCloud open...

It doesn't help, has i said : i allready do standard procédure to help (what you point) : update to lastest, disable extension or theme (i do not use), disable plug-ins... nothing helps, the bug is still there.
