2. F12 and run in Console (as per https://developer.mozilla.org/en-US/docs/Web/API/Permissions/query and discussion):

for (const a of [ 'accelerometer', 'accessibility-events', 'ambient-light-sensor', 'background-sync', 'camera', 'clipboard-read', 'clipboard-write', 'geolocation', 'gyroscope', 'magnetometer', 'microphone', 'midi', 'notifications', 'payment-handler', 'persistent-storage', 'push' ]) navigator.permissions.query({name:a}).then(e => console.log("permission for", a, ":", e.state)).catch(console.log);

EXPECTED:

There should be no 'granted' permissions.

ACTUAL:

TypeError: Failed to execute 'query' on 'Permissions': GenericSensor flag is not enabled.

TypeError: Failed to execute 'query' on 'Permissions': Accessibility Object Model is not enabled.

VM76:1 permission for microphone : granted

I don't know if this is a bug that should be reported upstream or it is may be related to the modifications in UC.

Is this still an issue in the latest ungoogled-chromium?

[nchv]

I cannot say for latest because due to the things mentioned in this issue I am running 72.0.3626.122 in which the result in the console is:

permission for clipboard-write : granted
permission for midi : granted

The others don't show up but these two remain.

[Eloston]

This is quite old, let us know if this is still an issue.

[nchv]

This is quite old, let us know if this is still an issue.

In 81.0.4044.92-2.1 there are even more which are blocked in settings but show up as granted. Also persistent-storage now says "prompt" (is there even a way to disable it?):

This is an old issue, that didn't show much activity recently and probably lost its significance — closing. If you have any more information to add, let us know.
