FireFox Optimizer

Just some questions...

does anyone here used or using Firefox i don't have an idea on it but they say that it reduces the memory that Firefox use on your PC...

As far as i know it requires a registration and paid. You can try this, Fasterfox from the official site - Fasterfox - Performance and network tweaks for Firefox. - or from Mozilla - https://addons.mozilla.org/en-US/firefox/addon/1269

But before you can download it, maybe you should need some information about FireFox optimizer here: Reduce Firefox Memory Consumption with Firefox Ultimate Optimizer
