Is your native language missing? 
Translating the plugin is easy if you understand english and are fluent in another language. 
I described in the <a href="https://wordpress.org/extend/plugins/all-in-one-favicon/faq/" rel="ugc">FAQ</a> how the translation works.

As of WordPress 4.3, this Plugin is no longer needed. The next update will integrate the Plugin into the core site icon feature, to allow for graceful 
retirement of the Plugin.
Add a Favicon to your site. No bells or whistles; simply upload a (ICO, PNG, or GIF) file.
Note: Plugin settings can be configured via Dashboard -> Settings -> Favicon.

cbnet Favicon
