But this memory leak issue has left me with no choice but to switch to Chrome.
Running Lion on a Macbook Air with just 2GBs of RAM (I didn't know Air's RAM couldn't be upgraded when I bought it), Safari is literally impossible to use.
According to the Activity Monitor app in my Utilities folder, "Safari Web Content" and "Safari" combined use a Gigabyte of RAM on average!
Other posts I've read either say upgrading to 6.0.1 resolved the leak, or deleting an addon/extension fixed it.
I turned off all my extensions, but the Monitor showed the same results.
Someone mentioned an app called FastTube that was silently eating up RAM, but I double-checked and I have nothing on my hard drive by that name. But now I'm wondering if there was some app I installed once and then forgot about which may have installed something into Safari that is now quietly eating up half my RAM.
If I downloaded and reinstalled Safari, would that disconnect any 3rd pary leecher apps? Would I need to delete my Safari preferences? If so, how do I do that without losing my bookmarks and such?
