Firefox is eating up my memory

Initially Firefox uses <100,000kb of memory when first opened. But after it has been open for so long, it starts to eat up my memory. Earlier i clocked it at 998,373kb when i realized my computer was slowing down. If i re-open Firefox, it starts off fine again but repeats the process

Hello, I am also having the same problem. 1GB memory it takes.
My config: 2 GB Ram, Windows 7 ultimate, core 2 duo 2.66 GHz.. I have several addons installed. How come it takes 1GB,. This is crazy lol..

When will Firefox stop eating all my memory?

For the past few versions, Firefox has been a memory hog. I have done a fresh install of my entire OS (Windows 7) and Firefox, ran it with no plugins, and still have the problem. I've got my plugins installed now and it's not much worse than it was before. This is ridiculous. It regularly consumes up to 700+MB of memory and if I don't monitor it carefully, it will creep up to over 1.5GBs. Not even Photoshop is that obnoxious to me.
== This happened ==
Every time Firefox opened
== Ever since 3.x or so

Ok, I found the solution (for at least my boxes!) Yay!
The trouble is that Firefox changed the amount of HTTP connections it permits simultaneously from 30 (pre version 6) up to 256 for version 7. Each connection uses CPU and Memory!!!!!
I won't ponder why they did that, but the fix is easy:
Lower the max number of HTTP connections
In the Location bar, type about:config and press Enter.
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
In the Filter box at the top, type network.http.max-connections.
Double-click on the network.http.max-connections preference, the "Enter integer value" dialog box will open.
In the field, type 30 which was the default value in old versions of Firefox and click OK.
My version 7.0.1 firefox suddenly started working! Yay!

How do i make the vurtrel memory smaller, it eating all my memory, and i have to shut down alot cuz it freezes my computer.

every time i open firefox it eat tons of memory in both the VM, and Usages, then my CPU will start getting really high to a point where everything stops working. It only happen since the last two updates I have did with firefox, but getting to a point where i am thinking about going back to explore. I really like firefox too.

That would be command + 0 (zero) on a Mac.

Upgraded to IO6, seems like the amount of system memory to run is higher, this causes issues with some Apps. I can't get SIRI to work because the amount of free system memory is not enough. how can I tell what is eating the system memory?

Every time I load my igoogle home page opening firefox, it opens it in two tabs instead of one, and then AVG tells me firefox is using too much memory and I should close and reopen it; Why

I open firefox using my igoogle home page and immediately it opens two igoogle tabs on top instead of just one how do I stop it from opening the second one? and then after about two minutes AVG tells me firefox is using too much memory slowing my machine and tells me to close and reopen fire fox...how do I fix that?

Make sure that Firefox closes properly and that that there are no longer Firefox or plugin-container processes left on the Processes tab in the Task Manager. Otherwise session restore will reopen the page(s) from the previous session.

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, 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]]
* https://www.mozilla.org/security/known-vulnerabilities/firefox.html
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.

TosOBEX.exe eats up my Memory

Hello,
I'm currently using the Toshiba bluetooth stack, that came with the billionton BT Dongle, to manage my BT connections. The BT manager works fine, but I've noticed that TosOBEX.exe eats up my memory causing my PC to run slow. I figured it's the problem 'cause when I end TosOBEX.exe, my PC speed gets back to normal.
Is this normal? Or did I do something wrong?
Thank you?

Is your bluetooth stack up to date ? If not update it.

In your case I would also check your COM ports. Maybe there is a conflict with an other device.

Avg tells me firefox is using too much memory,close and restart

avg pops up and tells me firefox is using too much memory.close firefox and restart it.page gets slow when this happens

Now using Firefox 7 I'll give it some time and let you know the results Thanks Jack

Why does my laptop give me a warning saying that firefox is using too much memory and to restart firefox to be more efficient? I just bought this laptop so I know it has the power to run what I need it to.

You appear to have AVG installed:
*See --> http://forums.avg.com/ww-en/avg-forums?sec=thread&act=show&id=173969#post_173969
From reading on the internet, it appears that when there is a spike in memory usage, AVG "interprets" that as a memory leak, possibly caused by malware. AVG could be incorrect concerning that assumption. Maybe they are being a bit too conservative about memory usage; just my opinion.
The decision is yours to turn off the "advisor" or leave it on.

Firefox 11 attempts an illegal memory access at 0x00000014 when shut down.

Firefox 11 attempts an illegal memory access at 0x00000014 when shut down.
I'm not sure if the previous version did so since I had it very briefly.
Other than an error message from W2000 I haven't noticed any unpleasant side effects.

As soon as Firefox opens, it starts increasing memory usage until it maxes out, and it won't actually close unless I end the process in the task manager.

Even if I'm not doing anything, no matter how few tabs I have open, Firefox will slowly increase in memory (RAM) usage until it's using nearly 100% of my computer's RAM, and everything basically freezes. Even when I close the window, the process continues to run, and I have to end the process in the task manager in order to get it to stop using RAM. I've tried disabling all my add-ons, and that does not help.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

I usually have 30 tabs opened, and the memory rises in a unexpected way, so that when it reaches 1.2GB, firefox crashes. Also If, for e.g. firefox is consuming 700MB of memory (with a lot of tabs opened), and if i close those tabs and leave just 2 or 3 opened, the memory usage does not drop and remains at the 700MB. Thanks for your attention. Regards, Ricardo

I have the same sort of problem with 30-40 tabs, with memory usage growing until crash. It seems a lot worse after restarting from standby mode on Vista - it's often highly unresponsive for a while, then crashes.
I have a fair few plug-ins running, one of the benefits of Firefox.
Is their a way I can log memory use of parts of Firefox, particularly the plug-ins?

Firefox is eating up memory, running at about 650Mb

Anybody got any ideas about how to stop this?
its making the use of mission control and other apps very slow.

My head swims on many of the Safari forum memory issues but even where it sure seemed like the user did everything suggested to remove xyz to resolve and get it under control, not always successful. the folks with points and Levels though tended not to have created or had an issue, just the known issues and cures.
Web content should not skyrocket RAM usage.
Safari 5 was not multithread / multicore and not optimized - for me, opening 100 tabs in 5 windows with Firefox is easy, Safari would be brought to its knees or give up trying and fail to open.

Why Firefox 5 eating up 1074424KB of my 2027520KB physical memory, with 9 tabs has loaded pages and 6 problem loading page as i stoped them?

Firefox was minimized i was doing something else but while switching to another application the screen got frozen, when it become normal i checked Task Manager and got Firefox is using 10744424KB (almost 53% of physical memory). As stated in question 9 tabs finished loading and another 6tabs showing problem loading page as I stopped them clicking on offline mode and when they stopped loading I switched to online mode.

Yes, Safari Web Content can use a lot of RAM. However, I don't think that would be the cause of crashing; lots of memory use rarely causes crashes. Poorly written software that runs in kernel space (AV software fits this), can cause this.
Safari Web Content is "caching" a lot of stuff. More than I'd like it to. If you have 47 tabs open, and close them down to 1, SWC will still often be taking up a lot of RAM. If you quit and restart Safari it will give the memory back, though in general if the system is under memory pressure I think SWC will also release some more RAM. In general I never notice this to be an issue.
I think with OS X Mavericks things may improve as well, based on details on the Safari tab, as well as with "Compressed Memory" which would help as your system approaches using all its RAM:

Firefox is eating up between 90% CPU usage to %230 CPU usage, while on a text-only page. I've tried many of the fixits. They didn't work. What can I do?

I've cleared cookies multiple times
I've emptied the cache
I cleared my download history, and a majority of my browsing history
I've tried having hardware acceleration for both flash and firefox on and off
I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.
I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.
A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement.
The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.
Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.
I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.
I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.

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
