How to reduce Firefox memory usage to 300kb

As you would know Firefox is the worst offender when it comes to RAM consumption. Previously I should you some memory optimizing techniques to reduce the memory usage in Firefox, but still it doesn’t significantly reduce the memory usage.

Firefox Ultimate Optimizer is a tiny yet a god’s sent program that reduces Firefox memory usage. You’d be surprise to see the memory usage coming down to around 200 to 300 kilobytes…. What the f#$% 300 kb ? Yes this ain’t fake, it really reduces the memory usage to less then 300kb. Even with five to ten tabs and many extensions running memory usage didn’t went up from say 2mb. I’m just really surprised by this app. In one word “marvelous”.

How to use?

1. Download the .zip file from here.(Link2)
2. Extract it to a separate folder.

3. Start Firefox Ultimate Optimizer.exe, it will be minimized to taskbar.

4. Now you can start Firefox

For some reason which i can’t figure out …… the official site doesn’t seems to open. So you could download with the links given above.

    this app does not work, it will come up with the message firefox optimizer has encountered a problem and needs to close.

    hmmm , it is working …. for me….. but then …. to compensate the very very low memory usage , seem it take more CPU usage

    The CPU and the Virtual memory gets some strain using the app. Yet still Firfox doesn’t eats my physical memory.

    THIS PROGRAM DOESN’T DO SHIT. IF YOU LOOK CAREFULLY IT SAYS IN THE LIST THAT ITS ONLY TAKING APPROX. 2 MB OF RAM, BUT IN REALITY ITS STILL TAKING UP THE SAME AMOUNT. IF YOU WERE A GENIUS LIKE ME YOU WILL FIGURE THIS OUT.

    BECAUSE IT JUST USES VIRTUAL MEMORY RATHER THAN PHYSICAL MEMORY

  6. YOU SPELLED GENIUS WRONG

    THANKS A LOT MAN WOW YOU REALLY ARE SMART. THANKS FOR ALL CAPS LOCK, OTHERWISE I WOULDNT HAVE NOTICED YOUR COMMENT.

    wow, you guys diss this, but it helped me atronomically! firefox made it so when I was surfing, i couldn’t watch ANYTHING on the side, or do much of anything. Now I can move a 7 gb floyd disconography to my external hard-drive, watch a shitty action movie, download at 500kb a second on utorrent, and surf the web all on a shitty eight year old dell 4300 S, yes the compact and less powerful version, maybe my cpu will fry, but ill be multi-tasking up the wazzoo till then…

    You may want to try this tool as well, called Minimem: http://minimem.kerkia.net. It does the same but more:
    - Can optimize other apps too
    - Smaller footprint though it does more
    - User-defined frequency of memory reduction
    - … and it’s not referenced as adware by Kaspersky!
    I use it on my old computer and it works like a charm with Firefox and a few more apps.

    Chrome..it’s the solution.

    Chrome is not the solution at all: it creates one process for each tab and, when you sum up the total amount of physical memory all of those processes use (easy as they are all called Chrome), you can find a total that’s even higher than with Firefox 3. Now the good news is that Minimem will minimize this very well: just select Chrome once and all processes will be adressed, and you can even optionally not minimize RAM usage for the one page you are currently viewing which makes Minimem very appropriate for Chrome.

    Buy some memory, you cheap bastids!! Compaq and Dell have been selling loser systems to loser consumers for years now, claiming than 128 MB of memory is “adequate”. They are totally WRONG!! The MINIMUM memory for WinXP is 512 MB. Recommended memory is 1 GB. Max is 4 GB, unless you have 64 bit version, in which case you can install all that your mainboard will recognize. Memory is cheap these days. Increase physical memory, limit virtual memory to about 1/2 of your total physical memory, and you’ll be happy as a pig in shit.

    And, good GOD!! PLEASE do not make some witty comeback telling me what Microsoft says is “recommended” and “minimum” memory. Those figures are part of Microsoft FUD. Unfamiliar with the term? Use GOOGLE. Stop being losers. This is 2009, not 1999. Reality check, aisle 6!

    This works great. Not only that but it is free. Wonderful. Five Stars. A+.
    The 300 kb is however slightly deceiving because it does take about 1500 to run the optimizer. Overall huge improvement. Thanks.

    Using such a hdd will definitely save my data in safety :)

    ‘Firefox Ultimate Optimizer’ is a fake because it pretends to reduce memory usage but if you check the total amount of usage memory of all running processes, you’re gonna see that it has increased.

    Not that I’m totally impressed, but this is a lot more than I expected for when I stumpled upon a link on Furl telling that the info is awesome. Thanks.
