AdNauseam's required permissions are based on those of uBlock Origin. We add one additional permission (monitor extension usage and manage themes) which we use to check for other addons that might conflict with AdNauseam, and then to issue a warning for the user. Here is a link to the relevant code.

These are the required permissions as specified in AdNauseam's manifest:

"permissions": [
    "privacy",
    "storage",
    "tabs",
    "unlimitedStorage",
    "webNavigation",
    "webRequest",
    "webRequestBlocking",
    "<all_urls>",
    "management",
    "contextMenus, (chromium-only)"
    "menus", (firefox-only)
    "dns" (firefox-only)
]

See uBlock's documentation on how specific permissions are used below:

• "Access your data on all web sites"
• "Access your tabs and browsing activity"
• "Access IP address and hostname information"
• "Store unlimited amount of client-side data"
• "Change your privacy-related settings"
