The Cookie Manager add-on requests the following permissions:
- Access your data for all websites
- Access browsing activity during navigation
These permissions are only used to provide cookie management functionality. The add-on does not use data for any other purpose than cookie management on your behalf (while interacting with the Cookie Manager user interface).
The Cookie Manager does not require network activity, except when necessary to work around Firefox bugs (in Firefox 55 and earlier). You are asked to for consent and a confirmation before such requests are sent.
