Thanks, but this still isn’t for me.
Do you know how to make startup of firefox faster?
Does adblock plus affect it too much?

thanks for your suggestions but think practically……in ram os programs are running and when you access any website or any programs taking all remaining space in RAM …so RAM is size does matter,,,,obviously less RAM less speed
4096 /256mb it will affect speed of Firefox
second thing when we are adding any extensions, it means they are taking memory in your Firefox program, they are running when you start your Firefox
and it will make slower to program ,simply take the example of internet browser in which most of the extensions are already included

So when you lessen the value of ram in the browser.cache.memory.capacity does this affect the amount of data that can be loaded when you’re watching a movie that’s being streamed?
