How Can I Get Safari Back to it's Original State?

Question

I recently noticed Safari taking up an amazing amount of memory. If I opened 5-10 tabs activity monitor would show that all memory was used, and safari would slow to a crawl with beach balls left and right. I thought Safari was simply a memory hog. But the other day I decided to create another user account and use Safari in the same way I use it on my original account.
On the new account I opened 5, 10, 25 tabs and I still had plenty of memory left over. So I'm guessing something I did with Safari, an added extension or something, is causing the memory link. I thought about simply switching to the new user account, but that would take a lot of work. Instead, I'd like to 'fix' Safari in my main user account. I know I can uninstall all extensions, but what else can I do to get Safari as close as I can to it's original state, and hopefully fix the memory issues.
Any help would be greatly appreciated! Thanks

When the same problem exists in multiple user accounts, the startup disk may need repairing.
Launch Disk Utility  (Applications/Utilities) Select your startup disk in the panel on the left then select the FirstAid tab.
Click: Verify Disk  (not Verify Disk Permissions)
If the startup disk needs repairing, follow the instructions here.
