The best to refresh your favicon is to go directly to the favicon image.
To Perform a Force Refresh in Firefox
- Using Firefox, navigate to your website.
- Change the URL to point directly at your favicon image file at the root of your site. For example, http://webhost.pro/favicon.ico
- Right-click in the browser window and select Refresh.

The forced refresh prompts Firefox to reload the icon instead of a cached version. The updated icon displays in the address bar. However, you may need to restart Firefox to get the icon to display on tabs and in Favorites.
Also sometimes just clearing your cache or rebooting your browser will refresh it.
