Dashicons is the official icon font of the WordPress admin as of 3.8. Some of you have requested that we add a feature to remove Dashicons. Some themes and developers utilize this (
dashicons.min.css) on the front-end of their sites.
To remove and disable Dashicons click into the Perfmatters settings and scroll down. Enable the feature to “Disable Dashicons.”
Note: This doesn’t affect the backend because the WordPress admin dashboard uses dashicons. This purposely only removes dashicons on the front-end when not logged in.
