nope, I did not restore from my old backups, i just set up my computer as new. For the extensions, I have adblock, youtube5 and fastest youtube.
youtube 5 is to automaitcally play all youtube videos in html5... i tried turning it off but it didn't make a difference.
Fatest Youtube is only a button to let me download youtube videos, so i don't think this is the cause.
i have read that adblock was causing memory for other users too, but the problem went away when they updated their adblock... I'm using the latest version as i just got it recently, so the problem shouldn't from adblock.
I just happened to have seen a post on another chat site about how "adblocker" is not compatible with Safari 5 or 6.
In this thread, they found switching to "GlimmerBlocker" solved it.
I have noticed my Safari 6 "leaks" RAM too. I don't know what is causing it, but it almost certainly one of my plugins or ad-ons.
I switched to FireFox for most browsing - my MBP is on for weeks at a time. If I were to reboot daily or weekly I could lkely use Safari more often.
In my Macbook Pro 4GB RAM recently note memory leak when I opened Safari even with 1 or two windows open without refresh the web content.
In Activity monitor could see consume Web Content the Safari Spend more the 2 GB RAM (Memory Real become Memory Inactive)
Solution: Disable All Extensions and probe one to one. Finding that Fastesttube Extension was responsible.
