Edit site permissions in Firefox

It used to be simple to edit site permission sin Firefox, you only needed to click the icons on the left of the awesome bar and you would see the connection security (encrypted/unsecured) and the permissions pane with the switches to allow as default, permit or deny.
Currently in Firefox 44.0.2, the Permissions pane only shows you the current permission of the site, not allowing you to edit them. To edit the permissions of the current site you have to:

1. Click on the icons in the left of the awesome bar, 
2. Click on the arrow of the panel describing the connections security



3. Click on the Button "More Information"



4. Click on the tab "Permissions"

5. Now you can edit the website permissions

To See and edit permissions to all websites, including the default permissions, you can type
about:permissions in the awesome bar.
