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.
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.

Why does Firefox use up so much memory? My Windows Task Manager shows it using 109 Meg just now asking this question. Thanks

Pretty simple: I want to know how I can keep Firefox from using so much memory when in use. 100-200 meg is common. Thank you

Hi musicfan,<br />Sorry you are having problems with Firefox. Maybe you should have asked earlier and we could have fixed it.
Reading your comments I do not see that rolling back to an insecure Firefox 22 will actually help you much. You are probably best using IE, unless you have also damaged that.
*[[Export bookmarks to Internet Explorer]]
You should not use old versions they are insecure. Security fixes are publicised and exploitable.
* [[Install an older version of Firefox]]

Most others will not be having such problems. We are now able to say that with confidence because after developers missed a regression in Firefox 4 telemetry was introduced so that data was obtained. It may be an idea to turn on your telemetry, if you have not already done so, and decide to stick with Firefox.

Trying safe mode takes seconds. Unfortunatly if you are not willing to do even rudimentary troubleshooting there is not anything we can do to help you.

Safari 2.0.4 - Uses a lot of memory ??

Hello,
I own an Intel iMac MA200.
I noticed after Safari's 2.0.4 update that it uses a lot of memory, sometimes even as much as 200MB
The cure I found is to restart Safari.
Sometimes, I need to even Force Quit it.
When I finish using my iMac, and close the Safari windows but let it keep running (red button), go to sleep, and in the morning check how much memory it takes, it's more then 100MB,
I suspect there is a memory leak with Safari 2.0.4
My OS X version is 10.4.8.
I wonder if there is a known problem with Safari, and if there will be a new update released soon (2.0.5 ?) that will solve this problem, because I didn't have this problem with 2.0.3 .
Thanks in advance,
Idan Mashaal.

Hey !
Thanks for the post!
Sience the Gmail upgrade, Safari stopped being my default browser.
I'm using JCraig's optimized nightly builds for Camino (1.2+)
They seem very memory friendly and Intel Optimized.

I really hope Apple will fix the memory leak and Gmail fix there new interface (the little option button next to the new reply deosn't work - even with WebKit nightly) ASAP - sience SafariBlock and Saft doesn't work well with WebKit Nightly.
I miss my Safari

Then the swf exit without any exceptions.The same code run at win7,just need 100M.
Can any give any suggestion？
Thanks.

I'm not sure what you mean by registering classes and functions. Have you tried running Adobe Scout on the SWF, it might give more info about what is taking up so much memory: http://gaming.adobe.com/technologies/scout/

Flash player 11.3.300.262 is using a lot of memory

Since updating flash a few days ago the plugin has been using a lot more memory than usual. Normally it uses between 150MB to 200MB, but now i have seen it use up to 900MB.
I've noticed that memory use increases by 5MB or more when navigating through a video until i have to terminate the plugin because of the ridiculous amount of memory used.

Please check if all your plugins are up-to-date. To do this, go to the [http://mozilla.com/plugincheck Mozilla Plugin Check site].
Once you're there, the site will check if all your plugins have the latest versions.
If you see plugins in the list that have a yellow ''Update'' button or a red ''Update now'' button, please update these immediately.
To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

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.

My ituneshelper.exe is using a lot of memory.

My ituneshelper.exe is using a lot of memory. I-tunes is not running and my I-pod is not attached.
Is there anything I can do about this? Can I stop this from loading at start-up and only load when I open I-tunes?
If so .. how???

The best thing to do is uninstall iTunes and install turn to him, but another look from thedownload page do not you reinstall the exe you have already installed ahy maybe youriTunes installer is in bug

ScanToPCActivationApp.exe is using a lot of memory even though the printer is off.

ScanToPCActivationApp.exe is using a lot of memory even though the printer is off.
Upon computer boot up, Task Manager shows it is using 45mb, and after researching this topic using IE, 10 minutes later it now shows it is using 74 mg, although it did go down to 33 mg a few minutes later, then back up to 51 mg a few minutes after that.
Is there a way to keep it from using so much memory when the printer is turned off?.
I am running Windows 7 on a Samsung Series 7 laptop and my printer is an HP 8600 All-in-one. I do use ePrintCenter occasionally, and also have a MacBook Pro (running Mountain Lion), and iPhone 4 (running the latest IOSupdate) and all devices connect to the printer wirelessly.
Please let me know if there is more info that you require. Thank you in advance!

If so, try clearing the Downloads Manager.

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

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

Why is firefox using the (presumably broken) RC4 128bit SSL encryption as highest priority default encryption?

128 bit encryption is no longer a real security deal. There are known attacks on RC4 and there is a warning from NIST to do not longer use it in a new product.
Firefox uses an internal list on prefered cipher suites. Why does firefox do not request for 256 bit encryption as default (AES and Camellia) and in a second step, if negotiation with an outdated server fails, fall back to 128 bit encryption? I know the user can block 128bit from about:config, but why is such an insecure and outdated SSL encryption option the default behaviour?

You can disable the 128 bit RC4 ciphers by setting the related security.ssl3.* prefs to false.<br />
If you need to visit a server that only works with an 128 cipher suite then you can enable one or two 128 SSL ciphers.<br />
Note that some servers host CSS files on such servers with older server software.

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
