webext-permission-toggle

WebExtension module: Browser-action context menu to request permission for the current tab.

• Browsers: Chrome, Firefox, and Safari
• Manifest: v2 and v3

Works great when paired with webext-dynamic-content-scripts if you want to also inject content scripts on the new hosts.

This repository even includes a customizable guide to tell your users how to use it. At the bottom of that page, you'll find a link that lets you customize it with your extension’s name and icon. You can link your users to it directly, it's a permalink.

Install

You can download the standalone bundle and include it in your manifest.json.

npm install webext-permission-toggle

navigator.importScripts(
	"webext-permission-toggle.js"
