I can not seem to get favicon icons in my favourites drop down in Safari 8.

[AppleFreak2299]

I have no idea why, but ever since the release of Safari 8, I can not get favicons of bookmarks of things. Some work, like the MacRumors, and some do not, like Best Buy. It has a stupid little Safari icon, with the dominant colour of the icon.

Here is a screenshot. As you can see, my tech news folder works, but Best Buy does not work.

Is there something that I am doing wrong, is something that the webmasters need to do with their favicon, or is it something that Apple is planning on fixing in El Capitan?

Thanks for any help in advance!
