Browser permissions viewer

The list is read through the browser's Permissions API when the page loads. Reading a state never asks you for anything.

States are what your browser reports for this site only. Browsers differ in which names they know, so "not supported" means this browser does not recognise the name. Change a permission in the site settings (the icon next to the address).

Runs in your browser: nothing you enter is sent anywhere.

How to use it

Open the page. The table fills in a moment later.
Read each row: allowed, ask, blocked or not supported.
After changing a setting in the browser, press Check again.

How it works

For each name the page calls navigator.permissions.query({ name }). A resolved state is shown as is; a name the browser rejects is shown as not supported. Nothing is sent anywhere.

Worked example

On a fresh visit in a browser that knows the name, camera and microphone usually show “Ask”, and location also “Ask”. After you block notifications for the site, its row shows “Blocked”.

Tips

Private windows start with no saved permissions.
A permission can be granted on one site and blocked on another; this table is for this site only.

Frequently asked questions

Does this page ask for any permission?

No. It only reads the state with navigator.permissions.query, which never shows a prompt and never turns a sensor on.

What do Allowed, Ask and Blocked mean?

Allowed means the site may use the feature without asking. Ask means the browser will prompt when the site first uses it. Blocked means it will be refused without a prompt.

Why are many rows marked not supported?

Each browser recognises only some permission names. Chrome knows more of them than Firefox or Safari, for example.

How do I change a permission?

Open the site settings from the icon beside the address bar, change the setting, and press Check again. The table also updates after you reload.
