 * I installed 2FAS Two Factor Auth plugin today and have found that generating 
   the Backup Codes does not work in Firefox, it does however work in Chrome.
 * This is the error I get in the latest version of FF:
 * `SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON
   data[Learn More] dashboard.min.js:1:35`
