The about:permissions page has been discontinued because it is missing a lot of settings You can use "Tools > Page Info > Permissions" to check the permissions of the current tab. You can find all available about: pages listed on the about:about page.

Ok, Page Info also doesn't have full screen mode listed--where did it go?

Hi brettz9

The Full Screen mode permission is no longer present in "Tools > Page Info > Permissions". With the currently used Full Screen mode API you get a notification pop-up when Full Screen mode is initiated via JavaScript (i.e. you click a button on the web page).

In fact I have found an other possibility. My Firefox is in french so I don't know how it is written for you all (because like you can see my language is not english) but in "tools" "options" "privacy (or I don't know how it look for you)" I go to cookies and there is "exceptions" and there we can put an internet adress of sites we want to block or accept the cookies.

I think this replace the page about:permissions.

Have a nice day !

You could always do this for cookies via the exception button in "Options/Preferences > Privacy". Note that all exceptions are stored as part of the Site Preferences and clearing Site Preferences will clear all exceptions that you have created.

• clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exception for password and other website specific data

You can see exceptions for the domain in the currently selected tab in "Tools > Page Info > Permissions".

• click the "Site Identity Button" (control center 'i' button) at the left end of the location/address bar
• click the arrow to expand the security message
• click "More Information" to open "Tools > Page Info"
• click "Permissions" to inspect and modify permissions
• click "Security" to inspect and modify cookies and passwords in a standalone window

• click "View Cookies" in "Tools > Page Info > Security" to inspect the cookies from the domain in the currently selected tab
• click "View Saved Passwords" in "Tools > Page Info > Security" to inspect the passwords from the domain in the currently selected tab

Ok, well thank you all !
