HI,
Try emptying the Safari cache more often. Click Safari in the menu bar then click *Empty Cache*. Relaunch Safari. If it Safari still freezes try troubleshooting the Safari .plist file.
Open a Finder window. Select your Home Folder in the Sidebar on the left. It has a small house icon. Then open the Library folder then the Preferences folder.
Move the
com.apple.Safari.plist file from the Preferences folder to the Desktop. Now launch Safari. If Safari doesn't freeze, move the .plist file to the Trash.
Web pages include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
In Safari / Preferences - Security. Disable plugins. Relaunch Safari. If Safari doesn't freeze, then you may Safari third party outdated plug-ins. Go here for help with that.
Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Right or control click the Safari app icon in the Applications folder then click *Get Info*. In the Get Info window under
General make sure that the: Open in 32-bit mode or Open using Rosetta boxes are not checked.
