Ever since I updated from 10.8.1 to 10.8.2 I have noticed that Safari has been hogging so much RAM. For example right now, with only this tab opened, Safari uses 250MB and Safari web Content uses 1,03GB. There are times that I experience lag when moving/scrolling through applications until I quit and reopen Safari. Is there a way to maybe reinstall Safari or any other way to solve this? I have a mid-2012 2.3 MBP with 4GB of RAM.
