Recently I tried to change the favicon for one of my blogs but it did not work or show properly.
Actually it worked in every other browser instead on Safari, it would just show the sites default icon, no matter how many times I quit Safari and cleared cookies for the the website.
So I remembered there is quick fix for this right in the top toolbar, it works perfectly.
Here is how to quickly fix the problem of favicon not showing or updating on safari browser:
Develop > Empty Caches > Refresh Website Page.
