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.

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

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…
