How do I make all of the images of the icons show in Safari Favorites?

It is the forum software. Sometimes images are not shown.

I added google to Favorites and it does show up.

Try deleting Google sites from Favorites and add those back again.

Safari > Bookmarks > Edit Bookmarks > Favorites

Highlight those and delete.

To add those back, visit those sites.

Share > Add Bookmark > Favorites

Try emptying caches.

Safari > Preference > Advanced

Checkmark the box for "Show Develop menu in menu bar".

"Develop" menu will appear in the Safari menu bar.

Click Develop and select "Empty Caches" from the dropdown.

Delete Caches.db

Close all windows and quit all applications.

Hold "option" key down and click "Go" menu in the Finder menu bar.

Select "Library" from the dropdown.

Library > Caches > com.apple.Safari > Caches.db

Right click the Caches.db file and select "Move To Trash.

Close windows and relaunch Safari.

Safari > Preferences > Privacy > Cookies and other website data:

Press the”Details” button. A sheet will drop down.

Enter YouTube in the search box at the top right corner.

Highlight the YouTube entries that show up.

Click the “Remove” button at the bottom, then “Done”.

Safari > Preferences > Extensions.

Turn extensions off and launch Safari to test.

All icons show in the Favorites dropdown. None is grayed out.
