Disable Safari 5 Top Sites feature

"Changes take effect after the next launch of Safari."

Did you delete the old jpgs & pngs in: /Users/beren/Library/Caches/com.apple.Safari/Webpage Previews (quit Safari first)?

Thanks. I'll try deleting the cache and see if any more images get saved. I thought I had done that when I reset Safari.

Surprisingly, even though this was written for Safar 4, it worked for me on Safari 5.1

Open Terminal in OS X and type:

defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO

To restore Tabs on Top type:

defaults delete com.apple.Safari DebugSafari4TabBarIsOnTop

I use an awesome little utility app called Hazel. You can set it up to automatically delete files in folders based on any number of criteria. I created a rule so that every time Safari generates a webpage preview, Hazel comes behind and sweeps it into the trash. Works likes a charm. The app also deletes related files when you trash an app, a huge plus. Cheers.

The fix on Aug 2, 2010 by Arimatheia and the modification by Steko worked without a hitch on OS X 10.7.4, and speeded up Safari at the same time, Thanks!

Even better:

Clear your top sites, then lock the offending file in your Library:

~/Library/Safari/TopSites.plist

Mine looks like this:

<?xml version="1.0" encoding="UTF-8"?>
