Firefox 52 and Safari 12 have removed all support for Netscape Plugin API (NPAPI). Plugins such as the mydlink plugin, Silverlight, Java, and Acrobat are no longer supported. mydlink portal uses mydlink plugin to access mydlink devices, and since mydlink plugin no longer works, Firefox and Safari 12 users are stuck at the plugin download page. Please note that customers using Firefox 51 or Safari 11 are not affected. Internet Explorer still support these plugins. 

Firefox users may download and install Firefox 52 ESR (Extended Support Release) which still support mydlink plugin. Note that Firefox ESR 60 has also removed NPAPI plug-in support.

The Firefox 52 and Firefox ESR browsers can co-exist on the same computer. We suggest keeping both browser versions on your computer.
