Answer 1

Back up all data if you haven’t already done so. Before proceeding, you must be sure you can restore your system to the state it’s in now.
Last warning: DO NOTHING unless you have a backup and you know you can restore from it.
Quit Safari if it’s running.
Step 1
Select /Applications/Safari in the Finder and open the Info window. There’s a checkbox in that window labeled Open in 32-bit mode. If that box is checked, uncheck it. Close the window.
Open the Library folder in your home folder as follows:
☞ If running Mac OS X 10.7 or later, hold down the option key and select Go ▹ Library from the Finder menu bar.
☞ If running an older version of Mac OS X, select Go ▹ Go to Folder… from the Finder menu bar and enter “~/Library” (without the quotes) in the text box that opens.
Delete the following items from the Library folder (some may not exist):
Caches/com.apple.Safari
Caches/com.apple.WebKit.PluginProcess
Caches/Metadata/Safari
Preferences/com.apple.WebKit.PluginProcess.plist
Saved Application State/com.apple.Safari.savedState
Leave the Finder window open. Try Safari again.
Step 2
If it still doesn’t work right, quit, go back to the Finder and move the following items from the open Library folder to the Desktop (some may not exist):
Cookies/Cookies.binarycookies
Cookies/Cookies.plist
Preferences/com.apple.Safari.LSSharedFileList.plist
Preferences/com.apple.Safari.plist
Preferences/com.apple.Safari.RSS.plist
PubSub/Database
Safari
(Note: you are not moving the Safari application. You’re moving a folder named “Safari.”)
Try again. This time Safari should perform normally, but your settings will be lost.
If the issue is not resolved, quit Safari again and put all the items you moved to the Desktop back where they were, overwriting the newer ones that will have been created in their place. You don’t need to replace the files you deleted in step 1. Stop here and post again.
If Safari is now working normally, look inside the "Safari" folder on the Desktop for a file named “Bookmarks.plist”. Select File ▹ Import Bookmarks from the Safari menu bar. Import from that file. Recreate the rest of your Safari settings. You can then delete the items you moved to the Desktop.
Note: This step will remove your Safari Extensions, if any, and their settings. If you choose to restore them, do so one at a time, testing after each to make sure you haven’t restored the problem.
If you don’t like the results of step 2, you can undo it completely by quitting Safari and restoring the items you moved or deleted in that step from your backup, overwriting any that were created in their place.
