Nowadays modern computers comes with high memory, from 1GB to 4GB and some even up to 8GB! Although powerful computers with high memory theoretically can multitask a lot of software together, but let us say if you load a firewall, an antivirus, Firefox browser, Nero Burning ROM, Adobe PDF Reader and a few more resource hungry software, you will feel that Windows starts to perform very slowly even if you still have a lot of free memory. Some of the symptoms are clicking the start menu and it is slow to appear, Windows Explorer takes a while to load and etc. That’s the reason why I don’t turn on the antivirus real-time file scanner even if I have 2GB of memory.
One of the biggest problem is using Firefox. I use it everyday and the hungry Firefox monster really eats up a lot of memory after using it to browse the web for a period of time. From the image below, it shows that it takes up 126MB but there were times that it can go up to 200+MB.

I know that there’s the “Ultimate Firefox Optimizer” which can reduce the memory usage from hundreds of megabytes (MB) to a few hundred kilobytes (KB). It is amazing but I’ve never used it nor posted it on this website because it doesn’t have an official website which makes it unreliable. Scanning it on Virustotal (36 antivirus) and 13 antivirus detects it as adware. Even Kaspersky’s Virus Analyst Vyacheslav Zakorzhevsky confirms that it is an adware.
Here’s an even better solution on how to reduce the memory usage for any running programs.
Minimem is a memory optimization solution to run modern applications on not-so-modern computers. Initially developed for Firefox only, Minimem now can reduce the memory footprint of any application. It runs in the background and can be set up to optimize as many processes as you’d like, using a very intuitive graphical interface. Unlike other memory optimization tools, it gives you full control over what applications you want to optimize, when and how often.

It optimizes memory by removing as many non-necessary memory pages as possible from the selected processes. It does so at regular intervals which can be user-defined as well and every 30s by default. This then optimizes your applications which can load those pages back whenever they need, and makes your overall system perform much better whenever it is memory limited.
Minimem remembers all of your settings; it is hence recommended to define once your processes to optimize and memory reduction period if you’d like to not use the default one, and then set Minimem to auto-start with your system. Its use will then become transparent to you and it will just do its job silently. Applications that are best to optimize for memory are typically office applications, typically word processors, and web browsers. On that last front Minimem has been tested to be extremely efficient with Firefox, the application it was originally designed for. Minimem does not replace your task manager and you should use this task manager if you’d like to analyse how much memory your various processes take; just press Ctrl-Shift-Esc to open it.

Yay! Minimem reduced Firefox’s memory usage to 12MB and it does that every 30 seconds! The best part is I can select a few more running application to automatically optimize the memory usage.

I only had this for a few months and then it says my license expired and to download to newest version, which I was already using, then it had an error message. I tried repairing and reinstalling and it didnt work. Any suggestions?
amazing tool dude.. thanks a ton!
its cool, it work on comp of my frend but dont work of my
it say error or something… :(
WHich site do i download this?
Check out the latest version of minimem. It now offers an intelligent engine that avoids taking lots of CPU cycles while optimizing like Cleanmem would do whenever it’s loaded. It stays in the tray and uses very little CPU and memory. And unlike Firefox Ultimate Optimizer, it gives you control over the memory reduction frequency as well as options to not optimize Firefox or other processes when you’re using the app or when it’s simply not required due to your system not have used up all of its physical memory. A really fantastic app imho, way better than most if not all not-so-free solutions!
The memory monster on my system is usually Firefox. Since I usually have 25+ tabs open at once, the browser often takes up an excess of 200MB of memory.
Anyway, the way I got around this problem was that I began to use Firefox Ultimate Optimizer. (I think Raymond mentioned it in an earlier blog, but I couldn’t find a link to it using several search methods.) Using the software, I was able to reduce the size of Firefox to well under 5MB… In fact, Firefox usually measures around 2MB in the Task Manager.
Unfortunately, Firefox Ultimate Optimizer must be loaded in the background for this reduction in memory usage to occur. But if you do the math (see below), Firefox Ultimate Optimizer has earned the 1.25MB of memory that it requires.
200 MB (Firefox w/o FUO)
– 5 MB (a “big” Firefox w/ FUO)
– 2 MB (FUO)

= 193 MB of memory saved

51.000k soz!
ummmmmmm weird raymond, mine never peeks above 51k even with a few tabs open and youtube ,and i dont have any mem tools ,only 1gb ram too
I have found system explorer to be a worthwhile replacement for Taskmanager which also allows you to do a memory cleanup manually which drastically reduces the memory usage of applications however imho its the virtual memory usage that takes the cake and slows down your pc a lot also.
I use CleanMem
pcwintech.com/cleanmem
Try it, it’s the best and doesn’t stay in memory.
Thanks Ray, will try it.. :)
All I can say is thanks Raymond! I have gotten a lot of great information and else from your newsletters and site.
thanks again
Thanks a lot , Raymond. :)
Now I can be assure that applications run smooth.
But are you sure it is stable and doesn\’t crashes the programs?
Vikas
this software got bug.. it only can reduce 1 program in 1 time..
if i input 2 program to be reduce, it will crushes
What can I say but absolutely AWESOME Raymond!
I used it, it effects the software when you re open especially Adobe Photoshop
Even with 4 tabs open, my firefox is only using 48 mg. Straight out of the box, no tweaks?!
Thank you so much Raymond!!! i needed this because my computer only has 512MB to spare and i noticed that firefox was eating all up. Now this is great.
thanks!
Interesting. To reduce the memory in Firefox I use the config.trim_on_minimize setting in about:config, but I’ll try this one. Thanks Raymond
this software is great, my vuze memory usage lower from 200mb to 30mb, now i can play garena while downloading…
Hey, that was real great mate, thanks a lot
Yay!!!
Awesome…
I thought it was just my PC, but it seems to alot having those problems.
Thank you for sharing this tip!! =)
Greetings,

thxx for the tip…i really help because sometime my pc hang a while if long time using firefox
As soon as i clicked on the processes, they dropped down to about 10k
but oh, great post, at least YM’s memory usage was reduced… cheers! thx raymond :)
Thanks for this cool tip. I have realised that firefox always run very fast but tend to use more ram as i surf longer.
huhuhu… minimem crashes when i try to optimize YM and Firefox… :(
nice post, i will try it
Great…!!!
Thanks…
Too bad it requires .net 3.0 :(
Great App. Thanks Raymond.
BTW, did you get email from me ?
Also, try Maxthon with IE7, or maybe Orca or Opera.
Great tip Raymond I was really looking for it,
along with this can I add this on my blog also with your Approval.
Thanks
AP
Does it take a painfully long time to reopen firefox?
And does firefox crash after long term usage?
