Firefox Eating Away RAM on my Leopard Machine

I am not sure if it is the right place to post this. I use Leopard on my 2GHz Macbook with 2GB RAM. Istat dashboard widget always shows that Firefox (v3 beta 5) is eats away all my RAM (between 260-300MB)? Is it some memory leak problem of Firfox or something to do with OSX? Should I not worry considering I have enough RAM? Any solution to give limited food to starving and greedy firefox.

Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop<br>http://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.

Adobe AIR 2.0.3 Installer does not work in Firefox 3.6.8 (win7/osx leopard) via badge installer

Using the Air installer feature of the Air App Badge installer from http://www.adobe.com/devnet/air/articles/air_badge_install.html
does not work in Firefox 3.6.8 on both windows 7 and osx leopard 10.5.8.
seems to be still functional in firefox windows xp and osx snow leopard 10.6.3
To reproduce. without having air installed on your windows7 or osx leopard machine, go to http://www.tweetdeck.com/desktop/ and click on the "Download" button to begin air install. the "Yes" and "No" buttons are unresponsive. Air will fail to install.

Firefox uses excessive RAM

I connect to the Internet via dialup. I know, but that's all that is available to me. Anyway, when I go offline and DO NOT TOUCH my computer, Firefox begins to eat up RAM, to the point that the cooling fan is absolutely racing and the computer is unresponsive to keyboard or mouse inputs. Remember, Firefox is IDLE and OFFLINE with gmail, Outlook, Facebook and two other tabs open. I have confirmed that Firefox is the RAM user by looking at Task Manager. Why is this happening?

Both Gmail and Facebook may monitor for changes and dynamically update the page. Typically these would be small amounts of data, but some add-ons may spring into action, for example, to pre-load or download videos.
Can you replicate the problem in Firefox Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled
In the dialog, click "Start in Safe Mode" (''not'' Reset)
Any difference?

When will Firefox consume less ram?

I use Mozilla Firefox as my primary web browser, it's excellent in almost every aspect except, it consumes too much ram.
Sometimes/most it eats up to 200-300 MB and it's not acceptable, will Firefox receive an update which will stop from eating so much ram?
I've looked for the tweaking to do in "about:config" it hasn't lower it down than the normal and also "Firefox Optimizer" it tells the user that it's consuming 400kb's but it's not true, only hiding the real facts.
As a everyday user of Firefox browser, I really want my number one browser to not be slow nor eat my ram!
== This happened ==
Every time Firefox opened
== Since I started using version 3, as I can remember.

Even in safe mode, Firefox 4 takes over 1500 megs of virtual memory and 800 megs shared. This is on a laptop with 2G ram, so it's almost half of actually consumed memory. I have a lot of tabs hidden behind Panorama, but those are not in active use so I'd prefer them not to be loaded at all at startup, only when I try to access them.

Snow Leopard machine will not allow anyone log in until reboot

Hi,
I am having trouble with my Snow Leopard machines (Mac Pro with 10.6.8). Most of time Macs will work fine but then all of sudden they will not allow any users to login (Not even local users). I have tried 3 locals accounts and root account as well but none of them will work. I have tried ARD to remote in but it will not work. Also tried to use SSH but it won't let me connect.
The only work around this issue which I have just to reboot that machine then all users can login.
Does anyone know how to fix this issue?
Thanks,

Hi,
When I see the machine sitting at login screen and I try to login using few different accounts (Local, AD, even root), it would shake and not go anywhere.
It will be really hard tell that something is goin on with that machine because there is no visible signs of any trouble until you try to login.
I am assuming that it should let login using local accounts even though there might be an issue with network which would cause a problem if AD accounts are used but nothing works at that login prompt, until I restart that machine.
Once the machine is re-booted then I can login with all the local accounts and re-check the active diretory settings to make sure that AD accounts can login. At this point problem will disappear for a while then few days later it will show up again randomly on different machines.
I have done all the OS X updates on all the machines using ARD but nothing seems to be working yet.
At this stage, couple of things come to mind:
Something went wrong with that lab image and I need to rebuild it which I will do it at later time. For right now I am only looking for temporary fix.
Using ARD, I have only done OS X updates but not the firmware update which might be causing this issue.
@Sanjampet: - I don't think that there is an issue with my password becasue it seems to be working after I have restarted that machine.
Thanks,

Firefox 4.0 RAM usage soars over time in Mac OSX 10.6.7 and is never freed

Firefox 4.0 RAM usage typically averages between 400-750MB for light usage (1-2 windows, 1-3 tabs each). Memory usage skyrockets over time, and/or if I open more tabs or windows where I've seen it consume well over 1 GB of RAM of my total 4 GB. Firefox 4.0 never seems to free much of this RAM relative to what it's consuming either.
The only plugins enabled are QuickTime, Flash and Java (and disabling any of these to use Firefox efficiently should not be required).
The worst I've ever seen was it using 1.27 GB of RAM when all I had open was Facebook (1 window, 0 tabs). Something is not right with this browser...Shouldn't it free what it isn't using?

Same here. I upgraded to FF5 yesterday morning and by this morning FF was using 1.26GB RAM and over 1GB Virtual Memory (less than 24 hours). I've had this problem ever since I started using FF with version 3...
The only add-on I use is Firebug.

Final Cut Pro X is eating my RAM.

I'm not sure what is going on here, but Final Cut Pro X totally eats up my 20 Gigs of RAM. The background tasks window shows zero activity, and all I am doing is trying to make cuts to the footage in my timeline. After an hour, the interface is sluggish (to put it mildly) and 4 out of 10 cut actions cause the program to crash.
I even tried opening the program and doing nothing. It STILL eats my RAM up in roughly an hour.
I have opened other projects from Final Cut 7 for some kind of comparison and I have not experience the same issue. Granted they are two completely different programs.
Any ideas?

Well, my setup works sweetly with 8 GB Ram.
Here I go with the same old boring checklist . . .
If you're getting crashes, autosave problems etc, there is more than likely some conflict on your system drive.
Create a new (admin) user on your Mac system and try FCP X from there.
I did this, and FCP X worked perfectly on the new account, meaning there was definitely a conflict on my existing system.
To be absolutely certain my MacPro's system was squeaky clean, I then did a clean reinstall (not TimeMachine) and FCP X has worked reliably ever since.
FCP X application should be in your Applications folder and ideally, your project and events should all be on an external HD and not on your Mac system drive.
I have over 3700 clips distributed between five events at the moment and FCP X is coping very well most of the time.
It helps to work without the waveforms displayed as these slow things down considerably.
Do you have FC Studio or a version of FCP on the same drive partition as FCP X? This is known to cause problems and not advised by Apple.
I quote from the Apple Support Website (23rd Sept 2011).
"It is strongly recommended that you install Final Cut Pro X, Motion 5, and Compressor 4 on a startup disk that does not have Final Cut Studio (2009) already installed. Use Apple's preferred installation procedure when upgrading one version of Final Cut Pro or Final Cut Studio to the next. This procedure is not unique to Final Cut Pro X."
Note that Apple use the word "strongly" - some people prefer to ignore this, and then blame Apple for all the sins on earth.
I don't.

Yosemite is eating more RAM

Hi i upgraded to Yosemite from Mavericks and now i am facing that my mac is eating more ram. please suggest me a solution for this

More RAM would mean that more apps could be open and run more efficiently. Remember, the OS requires a minimum of 1gb of RAM, FCE requires a minimum of 1gb, and then there's all those background processes running that you don't see; each with their own RAM requirements. So if you want to have FCE running along with a few other apps, more RAM would be recommended.
It would also help to keep things running smoothly if a minimum of 10 to 20% free space is maintained on all hard drives.

Copying LION to install on a Leopard machine?

I have a Snow Leopard machine and two Leopard machines. Has anyone downloaded, then copied then successfully installed on another Leopard machine?

Yes, I have...
But that requires that you save the "Install Mac OS X Lion.app" file before actually installing it on the first machine. The install process deletes the install app when it finishes.
You should have not problem downloading it again fro MAS on a second machine. If you then save the install app you can use it on a third machine without a download.
Or if you by chance had a backup run before the instlal started you might have captured a copy of the installer.
Unfortunately, this is the way Apple chose to implement the new install procedure.

More ram with snow leopard?

can a late 2008 MBP 2.53 hold 8 ram if snow leopard comes out?
right now my top is 4 gigs....it would be nice if this were possible

The limitation was hardware, not software. Snow Leopard won't change that.
...which is really unfortunate for those of us who had taken the plunge in late 2008.
Apple Insider had published a great article explaining it in detail, but I cannot find it right now.

Alas, I updated to Lion and need to remove Appleworks from laptop. What, besides the application (folder) else do I need to remove. I am putting items onto a CD so I may be able to work on a Leopard machine.

New MacPro 2008 freeze using Firefox 2.0.0.11 on Leopard 10.5.1

Hi
I'm using a new MacPro with Leopard 10.5.1. Surfing the web with Firefox 2.0.0.11 for three times I've had a monitor freeze with a lot of visual "noise". I must to restart the Mac. All the three times I was surfing on MySpace pages.

Hello TheAnt,
I don't think it is a Firefox problem. I normally use Apple's Safari, but I wanted to see if I had the same problem you seemed to have had posting a reply from Firefox. It works fine for me, as I am using Firefox right now. I still say you have a problem with a corrupted file in the program. I think if you just remove ALL of the files that are associated with Firefox, and you will have to look around because they are scattered around some, and reload the program again; all of your problems will go away.

Firefox eating excessive memory (highest I've observed it was 3.5 GB)

Upon start up my FireFox goes right up to over 130KB of ram, which is already a lot. Over a period of 45 mins to an hour, its consuming an entire 1GB of memory. Left unchecked it goes over TWO GB. One time I even saw it eating 3.5 GB and had my entire system running at a snails pace. That is beyond excessive. I've seen other posts about memory usage but none on this huge of a scale. If I can't fix it I won't use FireFox anymore.

hello, i agree that this totally unacceptable memory consumption. there have been many efforts going on of reducing the core browser's memory footprint - most of these excessive leaks are caused by extensions in the browser - which ones do you have installed in firefox > addons > extensions? (changes will be implemented in firefox 15 to dramatically reduce the possibility of memory leaks by these 3rd party programs).
you can also try launching firefox in safemode and see if it's working normally. if so, you'd have to try disabling all extensions, reenabling them one by one again & then observing the behaviour of the browser again to find out what's causing it.

Mountain Lion EATS-UP RAM and BATTERY!!!

Since I had the BAD idea to install Mountain Lion I have had only trouble.
1) Given the fact that Safari deosn't start and hangs endlessly, unless I ALWAYS force reload the pages, and given the absence - a REAL LOSS! - of functionalities like RSS which were in Safari 5.1.7 but not in Safari 6, I had to drop it as my favorite browser after MANY YEARS, and pass to Firefox which is FLAWLESS.
2) Another MAJOR issue that I want to mention is the fact that with M.L. my free Memory at startup, with the same login items, has gone down from an average of 6.9/7 Giga to a 5 Giga or less.
Even freeing memory doesn't help.
3) The other problem is a HORRIBLE DOWNGRADE ALSO IN BATTERY LIFE which has STARTED the moment I installed M.L.
Instead of the usual 7-7 1/2 hours, I now get about 3 1/2 hours.
I have done PRAM reset and permission repairs (which, BTW, take EVEN 10 minutes!!!) but to no avail.
And on top of it, EVERYTHING is much slower than with Snow Leopard!
A MAJOR SYSTEM UPDATE IS NEEDED URGENTLY!
This system for now s*u*c*k*s feet fungi! ...And one cannot go back to the previous system!!!

Thank you Thomas. Some common sense, respect and politeness helps.
Unless... I have no right to be upset at a system that was put out and for which I even payed (a first in 25 years for me with Mac) and someone finds "offensive" (who is he, the system's mom or child?) some very harsh (IMHO with reasons) criticism of this system!
To begin with, it would REALLY help if, INSTEAD OF SHOOTING answers which are NOT answers, one took the time to read the question well and to try and understand if the person who asks is a newbie or not (in my profile there is a 25 years of Mac experience), and may be NOT insisting on the creation of a new user account when a few messages above I had already written that:
"I not only created a brand new user account, I actually ever re-formatted the whole disk and re-installed the system ANEW, one week after the first install and after innumerable problems, and NOTHING CHANGED".
I consider the REPEAT of such a suggestion just disrespectful, since I had written that I had already done all that and more, and I find it also also upsetting, after one week of PURE **** with my computer, something NEVER experienced before.
In the meantime, I disabled the [for me] useless and actually annoying "Notifications" even eliminating it from the toolbar, and free RAM at startup jumped immediately UP about ONE GIGA, back to 5.2 out of 8, and, after using freemory pro (even if it really bugs me to have to do that everytime I startup!) I gain another giga, and I am back to something more normal like 6.2 out of 8.
However, no way for me to have Safari start without forced reloading (while Firefox is flawless) and I also still have the rest of the BUGS, not last of which is with Mail showing the "blocked plug-in" (after re-installing a brand new FlashPlayer with the new system installation) and not allowing Control-F in address field, which I had done since Mail was invented.
As another person, probably another "idiot" like me who doesn't know that Mountain Lion is perfect and it is all his fault, (I quote him): "I send out 'stuff' to a distribution of people (Bcc, of course) and always take pains to remove the original sender from the list. I then used to put the cursor in the list of distributes, hit Command + A then Command + F and "find" whomever it was I needed to omit. This handy feature is now disabled. Sigh."
I really resent that some people at Apple are so much under windoz influence that they have been eliminating one by one the great characteristics that made Mac a DIFFERENT system, above all a USER FRIENDLY SYSTEM.
Now it is much less so, and on top of it you have Mac users in this forum, who probably started with a PC (which I NEVER touched) who get upset when one points out the flaws in the new creations...
Besides some politeness and empathy, he should learn some English: it is "in the same VEIN", not vain...like his remarks... ;-)
