+The free article limit can normally be bypassed by removing cookies for the site.  
+Click on the BPC-icon and then 'clear cookies' button in the popup.  
+For user with the limited permissions BPC-version this will only work for supported sites; for other sites use:
 1. Install the add-on [Cookie Remover](https://addons.mozilla.org/en-US/firefox/addon/cookie-remover/).
 2. When coming across a paywall click the cookie icon to remove the cookies then refresh the page.
 
 If removing the cookies works you can also add the site as a custom site.
