AskBlocker插件简介

AskBlocker插件描述

Block overlyeager permission requests f notifications, location, etc. F example, ones that happen befe youve interacted with the page. This was created as part of How to improve your permissions UX (https://adamlynch.com/improvepermissionsux).

How it wks:

Permissions requests are blocked until youve interacted with the page; i.e. click, tap,  key press. Although there are the following exceptions:

 If the permission has been previously requested  granted ( explicitly denied).
 If the domain is `localhost`  `127.0.0.1`.
 If youve navigated to the current page from another page on the same domain.

Things not covered  why:

  Accelerometer, gyroscope, magnetometer, device motion, device ientation, etc. They dont trigger a permissions request popup.
  Ambient light sens. It doesnt trigger a permissions request popup.
  Bluetooth. This can only be requested due to user interaction anyway (https://webbluetoothcg.github.io/webbluetooth/#requestDeviceusergesture).
  Clipboard. It doesnt trigger a permissions request popup.
  Flash. I dont know how the prompt is triggered  how I can intercept this.
  Geolocations `watchPosition` method. Theres no way to achieve this without breaking stuff. It returns an ID  it doesnt offer any way to check the status of the permission, like `Notification.permission`. The Permission API could be used but its asynchronous (Promise based), so theres no way to use it  also still return the ID. 
  Web USB. Not really suppted yet ( the Permission API doesnt suppt it yet), so it probably wont be annoying anyone.
