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.
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.
It might be easiest to seek assistance from a forum more dedicated to malware cleanups such as the following:

My saved messages are using a lot of memory. How do I free up the memory?

My saved imessages are using a lot of memory (3.1GB) on my iphone. How can I free up the memory?

This is when I go to "usage" and it lists all of the memory used by certain apps. Messages is the largest, and I swipe to the left to open it and it says that "saved messages" are using all of it. There is no option to do anything at this screen.

Thank you for the link, but I am not sure how this is going to help me: I am not booting straight to an X session, but prefer to log into TTY1 and have my login shell handle everything from there.
Here is the relevant part of my .zprofile:
if (( UID )); then
[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec systemd --user
fi
As far as I understand, your method works if I enable the [email protected] template when actually booting straight to X.

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.

Firefox 28, 29 and 30 load pages very slowly - Google Chrome is OK on the same PC...?

Windows XP SP2 on a Dell Precision 340, Pentium 4, 2GB RAM, two GeForce MX4000 graphics cards, AVG Internet Security 2014. Broadband connection with download speeds up to about 27Mb/s.
I get the same symptoms on a homebuilt system with an almost identical spec.
Internet pages with any graphics at all load very slowly. Reliable websites like BBC News can take at least 30 seconds to open, making Firefox unusable for surfing.
Google Chrome, on the same PC, opens the same pages in about 4 seconds.
Firefox running under Ubuntu Studio 9, on the homebuilt PC, is also fine, so I don't think it's my internet connection.
Firefox 30, on Windows 7 64-bit Professional with Norman Endpoint Security, is fine on my work laptop.
What's slowng down Firefox 30 on my Windows XP machines please?

Sorry you are having problems. Thanks for a good descriptive post. There is a testcase; see under; does the globe spin slowly ?
Just a hunch at the moment but maybe the problem described in this thread.

Firefox is slow in responding to commands and loads pages very slowly.

I'm unable to use Firefox most of the time because commands are slow in running( like Scrolling down a page.). Most pages take forever to load and while they are doing so. Navigation crawls to a stop. I'm now using Chromium by Google because it's faster and I can continue to work the page while it finishes loading.

Thanks for replying Sisham.
My system meets all the requirements. I agree with you that with a better hardware installed the software will be much more usable, but I feel that, since my system is OK with the requirements, Illustrator should work much better, at least on the basic tasks. I'm especially concerned because Illustrator CS6 worked fine, and that version of Illustrator has got the same system requirements, so I'm not sure that with a better hardware the program would run normally.
There's no difference in managing complex files with multiple linked images or small low resolution files with a couple of objects: I have this delay in zooming and panning, selecting, moving objects...
I'm wondering if I should check any specific setting inside the program.

LSP causes firefox to load pages very slowly

I'm a developer for a company that produces content filtering software. Our filtering component is an LSP that monitors network traffic. For some time now, we've been experiencing periodic issues with Firefox and our LSP.
This is not a crash, and Firefox is not frozen. But when you try to load a page, Firefox comes to a point where it just spins trying to access the same socket over and over again. Clearly our LSP is doing something that Firefox doesn't like, but eventually Firefox breaks out of the spinning and loads the page.
I'd like to know if there is someone involved with Firefox development that I can communicate with to resolve this issue.

Hi coverton,
I did pm you:
You may not easily see this. Initially I do no want to answer your question on the forum, as an answer may then deter others from replying. This is not something that I understand but my suggestions are:
you say for some time you have had a problem 
if this is a Firefox regression which version did it occur on 
file a bug on bugzilla https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes|Firefox
 or you may in fact find it is a known issue, an example of a bug fixed in Firefox 13 is
 Bug 712363 - SSL connections do not work correctly when not managed by the socket transport service (including especially when the socket is not non-blocking)
 have a look through the mailing lists and forums you may find a useful one http://www.mozilla.org/about/forums/
 also consider looking on the various mozillazine forums http://forums.mozillazine.org/index.php
This sort of problem is probably slightly outside the range of problems we attempt to solve on this forum.
My view is that basically if the problem clearly does not exist in one version of firefox, but does from a certain later version then there was some sort of change, and if that was not intentional it is a regression and appropriate to file a bug for. ( If the change was intentional there will almost definitely be a bug filed documenting the change. )
If you do post a bug suggestions would be
* First try it in the latest nightly just in case the problem was fixed. http://nightly.mozilla.org/
*Try to narrow down a regression window, so please test in Firefox 10 and 11.
*There is a tool for narrowing down regressions by automatically downloading a bissected range of Nightly builds and running them in turn with a dialogue to confirm or otherwise that there is a problem (last time I tried the tool I had a problem with it but it was probably user error, or is now fixed )
** see https://github.com/mozilla/mozregression
Obviously you will need to rule out that it is due to changes in third party software, and to demonstrate the problem you will need some reproducible steps, so it could be appropriate to try discussing the problem on a forum in order to build some sort of test case prior to filing a bug.
As you have asked here it would be useful to know what happens so please post back if you file a bug or find a forum or mailing list that provides a solution.
Good Luck
P.S. I note you filed '''''Bug 756216 - LSP Causes Firefox to Load pages slowly '''''

Why are the pages still loading so slowly? Firefox is also still using a lot of memory. I've tried everything and still have the same issues. The new versions never help either. The support section still lists the same "solutions" that do not work.

I have spent too much time on the same issues. Will the issues ever be resolved?

i'm also having major CPU problems w/ FF 29.0.1. when i restart the app it calms down again but after loading tabs it steadily climbs up to 100% after not too long. i have checked out the 2 CPU links/articles above and do all the basic troubleshooting and tips, but with all the FF tools & add-ons isn't there some sort of CPU monitor that has the ability to display which extensions/scripts are hogging the CPU? Activity Monitor on Mac just shows the total used by the app. it's impossible in my case to efficiently disable dozens of add-ons & scripts, restart, and test each one by one b/c it can take several hrs before the CPU starts to spike high again. i have no time for this.
thanks

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.

Firefox 4.0 loads pages very slowly - will this be fixed soon?

I upgraded to version 4.0 and it is much slower in page loading then any of your previous versions. Are you going to be fixing this problem soon? Or do I need to look for a different web browser to use... Very disappointing! So much for FASTER than before - NOT!

It will work again if McAfee does a full update...

I have upgraded twice to FF 4.0 and both times I have had major problems with it not responding and loading pages very slowly.

I have once again gone back to the older 3.6 version. I love the layout of the new 4.0, but I hate all the lagtime and the fact that it stops responding every few minutes. Will this be addressed? I would much rather have the latest version, but the lags are annoying.

I have also updated to the newest version and enjoyed the new look and layout how ever I have experienced confusing issues. For a few months 4.0 ran without a hitch no problem in sight then all of a sudden each time I loaded any link I would experience no indication of it working. Loading up task manager it was running at least twice at demanding memory usage was also high. The cpu usage was just as it always was which was below 5% even with other programs running. It constantly shows that the browser is "(not responsive)"

Then drop down the tree of that program...then you will find option " Dict. Structures"..

HT5621 Me and my daughter are using the same Apple id and we share the same iCloud account. I want to change her Apple id so that she will have her own icliid account and I will have mine. how do I do it?

Me and my daughter are using the same Apple id and we share the same iCloud account. I want to change her Apple id so that she will have her own icloud account and I will have mine.
1. how do I do it?
2. how do I transfer her stuff which is in my icloud storage to her new icloud account once this one is created?
thanks,
Ari

To migrate her device to a new account, start by saving any photo stream photos she wants to keep to her amera roll (unless already there) by opening your my photo stream album, tapping Select, tapping the photos, tap the share icon (box with upward facing arrow, then tapping Save to Camera Roll. If she is syncing notes with iCloud, you'll need to open each of the notes and email them to her so she can later copy and paste the text into new notes created in her new account. Then go to Settings>iCloud, tap Delete Account (which only deletes it from this device, not from iCloud), choose Keep on My iDevice and provide the password to turn off Find My iPhone. Then sign back in with a different Apple ID to create her new account and choose Merge to upload the data.
Once you are on separate accounts you can each go to icloud.com from a computer and delete the other person's data from your account.

HT204053 My wife and I are using the same apple ID. since last week, i am required to pay twice for the same app on our 2 devices (even though we are using the same ID). what can I do to fix this?

My wife and I are using the same apple ID. Up until last week we used to buy an app and pay for it only once, but use it on both devices.
since last week, the app store asks me to pay again for an app i already paid for on one device. On both devices automatic downloads (in settings) is and was always turned off.
what can I do to fix this?

Actually no. After installing an app on one device, I used to see an "install" button on the second device (since it's already been paid for). Now i get the full price button on the second device. I didn't want to proceed with the purchase because i didn't want to be billed twice.
