I have a question about Firefox loading into memory. I read in a lot of forums that for the first time your start up your system, Firefox loads up slow. Maybe 10-15 seconds. But subsequently, it opens instantly like IE7 does. I've tried this on two of my friends' computers (who didn't have Firefox). I installed the same extensions as I had on mine. And true enough, except for the first time the computer starts up, Firefox loads almost as fast as Internet Explorer does.
Here's my question. How come that doesn't work for my computer? It takes 10-15 seconds every single time I open Firefox. It cannot be because of system specifications because my computer is twice as fast as one me friend's and four times faster than the other friend. And, I tried a fresh install by removing Firefox completely and having no extensions at all. Still it takes 10 seconds to load up.
I was wondering why there is such a big difference. The other 2 computers I've tried on are both Windows Vista. Only difference I know is that I'm running Zone Alarm and they're not. They both have AVG anti-virus as well.
I know about Firefox Preloader. But that's not much of a help. I can just use the Minimize to Tray extension and keep Firefox open all the time. I wouldn't ask for help if I didn't know why Firefox loads instantly for my friends and takes long for me.
