Firefox browser will not allow me access to permissions manager. I get a message saying the URL is invalid regarding about:permissions. The addons do not work either. I tried Foxy Permissions addon but there is no icon to attach toolbar and it does not work in firefox browser. Right click about permissions does indicate an icon but it does not work. There is a pop up message which also indicates this is an invalid URL.

hi sunseeker66, about:permissions was removed in firefox 45 - if you want to change permissions for a site you can do so through the site's info panel: Site Information panel
