Why is firefox 7b using a lot more memory and cpu on my computer?

I'm trying firefox 7 beta in a debian squeeze box. It is using a lot of RAM and CPU compared to previous releases of firefox(I've tried disabling all plugins and add-ons, not a big improvement). In the follow link here is a summary from about:memory, websites tabs opened at that time and the usage of % mem and cpu of my system: http://pastebin.com/8ji1gmLk
I'm using firefox on all my computers for a while now. So changing the browser is not an option for me now.
It did crash few times when loading a lot of tabs. Please let me know if there is another information that would be useful for fixing this. Thanks

Is it using a significant amount more resources than 6.0 did?
I noticed 6.0 is a VAST resource hog over 5.0 and earlier. It's a very bad flaw in the new version, and has a lot of people upset.
What has me curious is whether this is a new resource problem or whether it was present in 6.0 and you are just not noticing it.
One suggestion: Don't run BETA versions of ANY software on "all your machines". Not when rolling back the version is not an option. That's generally a bad idea, since beta versions are likely to have bugs.
With FF, now, I would never let it automatically update. I don't trust their new update policies, so I would suggest you turn "auto updates" to OFF, and do it manually, only after you hear the new release is stable, which we know 6.0 is NOT.

A process named "update.exe *32" and description is "Firefox" keeps using a lot of memory and cpu; the longer forefox is on, the worse it gets. How to prevent?

using Windows 7, firefox 15.0.1
This process uses more and more memory and CPU, sometimes there are several of these processes running. If I kill these processes, it doesn't seem to affect the utilization of Firefox. Then the process slowly starts to use more and more memory and CPU all over again.
This happens all the time, every time I use Firefox.

I do not have a ComObjects folder under C:\Program Files (x86)\Common Files. That is not part of Firefox.
wscript.exe is a utility included with Windows to run scripts at the system level. It generally is not used by major programs. If update.exe is starting up with Windows, you may be able to find the script that wscript.exe is running using [http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx Autoruns].
It definitely sounds viral. I suggest deleting the update.exe file, although Windows might prevent you from doing that until you kill all related processes. And if you have a persistent infection, the file may be restored or re-downloaded.

I have a macbook pro 1.5 years old ver10.7.5 and now having a problem with having to manually force quit after a hour or so of use to clear up memory(unit slows down) should I up grade iso if so to what

I have a macbook pro 1.5 years old ver10.7.5 and now having a problem with having to manually force quit after a hour or so of use to clear up memory(unit slows down) should I up grade iso if so to what and what is the correct procedure? Rick

To determine if it is, boot into Safe Mode and see what happens. http://support.apple.com/kb/HT1455
In the Activity Monitor, what are the Page Outs and Page Ins?

"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.

Ipod shuffle dose not show up in itunes and slow down my computer

hi i can see my ipod shuffle in my computer as removeable hard drive not my ipod name anymore and also i can't see my ipod in itunes at all and every time i connect my ipod shuffle it slow down my computer (very slow) and use my CPU 100% all the time my other usb hard drive(not ipod) works fine its only my ipod i also try to use all my usb port but its still the same thing.
and it can't be my windows because i have just reinstall windows 3 days ago
can someone help me fix this

I think I can add a bit to this problem.
My iPod stopped working during the first use after running the iPod Updater 2005-11-17. When a button is pressed both green & amber lights up.
When plugged into my computer, iTunes (vs 6.0.1.3) does not recognize it is there. Naturally, I tried to run the updater again (2005-11-17 version) and the program hangs. It does not use up the cpu though (~3%). Eventually, after ~5-10 min the updater recognizes there is an iPod and then the restore button can be pressed. However, soon after the updater gives the error "Firmware update failure. Disk write error"
I reinstalled iTunes and the iPod updater as well as tried to use the new updater (2006-01-10) and same error. I am in the process of checking the drivers now. But I still don't know what is causing this error...

Everyone does at one point or another. Please be a little more specific about when this occurs. Also you may find Spinning Beach Ball of Death useful to track down the reason yours is occurring.

Firefox 4.0 RC has huge memory leak + slow down problem

Firefox 4.0 RC Seems to have a huge memory leak issue. After leaving the program open for around half an hour the RAM usage climbs to over 1 gb.
However, I have 12 gb of physical ram, so firefox staking 1 gb for itself is not too big of a problem (and is probably a blessing as it means it's caching more data), but the problem is that the UI begins to slow down and become clunky after about 30 minutes.
Browsing, switching tabs, even typing becomes jittery and not very responsive.
This happens regardless of how many tabs I have open.
Now it's also crashing every once in a while.

Even with Firefox 4.0 (Release) running in Safe Mode, with all add-ons and themes disabled, I'm still inclined to think there's something screwy going on here.
I was watching Page Faults/sec, Page File Bytes and Working Set in Performance Monitor and tailing the Privoxy log for requests. Even with Firefox minimized and "doing nothing" (making no requests, anyway), over the space of a 10 minute period the Working Set grew from 244,375,552 bytes to 274,939,004 bytes (averaging 50,939 bytes/second). This behaviour doesn't seem consistent though - sometimes it doesn't seem to grow at all.
Additionally the Page Faults/Sec went nuts, accompanied by a step in Page File Bytes and Working Set, whenever a request got made to http://safebrowsing.clients.google.com/safebrowsing/downloads which seems to happens on a regular basis (approximately every 30 minutes).

Mobile device manager is using over 50% of my CPU and slowing down my computer, is there any way to change this? I have an Ipad and my kids have an Ipod so I can't disable this but I would really like to not have it running all the time

I recently got an Ipad 2 as well as an ipod touch. I have 2 laptops at home that I have synced the devices with, one is running vista and the other XP. Both of the computers are now running really slow and when I checked my CPU usage it is showing that mobile dvice manager is using around 50% of my CPU and it is constantly running in the background. I am wondering of anyone has any suggestions on how to keep dvive manager from running when my Ipad is not even connected to the computer.

My Firefox continues to stall a lot and Window Task Manager shows that Firefox is using a lot of memory (600,000k +) What can I do to make this stop stalling?

I play Farmville or on Pogo and my computer keeps giving me the hour glass and when I look on my Windows Task Manager it shows that I am using over 600,000 k of memory. When it does that I can't do anything unless I just use the power button to shut the computer down or use the task manager to "End Process". I do not like to do either of these so I usually just sit and wait for it to fix itself then later it does it all over again.
Also when I was doing defrag on the file type tab it showed two Mozilla Firefox so I am wondering if this is the issue but I only see one in the control panel.

Firefox and Thunderbird are using a lot of memory and load pages very slowly!

CPU levels are going through the roof when using Thunderbird and Firefox.
Both programs are freshly installed on a new and also freshly installed version of windows 7!
Loading of my pages is taking forever and most pages don't load at all.
My email is [email protected]
My notebook got so hot that it turned itself off!
Memory is above 250 KB for firefox and Thunderbird above 150 kb!

I do not have a ComObjects folder under C:\Program Files (x86)\Common Files. That is not part of Firefox.

Why is Firefox 6 using a LOT of memory on Vista x64

Memory usage on FF6 is 40% higher than FF5. Also, I have a lag when changing pages on a website. This is extremely irritating and did not happen with the previous version.

Is it using a significant amount more resources than 6.0 did?
I noticed 6.0 is a VAST resource hog over 5.0 and earlier. It's a very bad flaw in the new version, and has a lot of people upset.

I keep getting Norton 'performance alerts' that Firefox is using a lot of memory. Should I worry?

Is there some action I should take because of thes alaerts? It happens every time I start Firefox

This is likely coming from a third-party program. You can try to Reset Firefox. [[Reset Firefox – easily fix most problems]]

I keep getting a warning from nortons that firefox is using a lot of memory (125mb). Why?

i never got this message until i upgraded to firefox5. it also gives warnings about excessive cpu usage

Windows puts up messages that this is too much - also it crashes, gets stuck and moves like a very slow turtle
I am trying to remove the McAfee toolbar, having uninstalled McAfee, the toolbar remains - I suspect it is intruding space and time wise as I have AVG already
thanks for your response,
Jaiia

Whenever Firefox is open I have a line on top saying "Downloading the latest application" It seems to be costantly running and slowing down my computer. How do I get it to stop?

It happens all the time. On the line below Yahoo toolbar.

The "Downloading the latest applications" problem can be caused by the MSN® Toolbar (Tools > Add-ons > Plugins)
See [[Troubleshooting plugins]]
