> WebExtension module: Track `activeTab` permission; automatically inject content scripts

The main use case is to ship your extension without `host_permissions` and have the user invoke the extension on click on any website.

Alternatively, consider using [webext-permission-toggle](https://github.com/fregante/webext-permission-toggle) and [webext-dynamic-content-scripts](https://github.com/fregante/webext-dynamic-content-scripts) to permanently receive access to certain hosts and automatically register content scripts on it.

## Install

```sh
npm install webext-active-tab
```

## Usage

This package exports various utilities, just import what you need.

- [on-active-tab](./source/on-active-tab.md) - Watch when tabs receive `activeTab`
- [register-active-tab-scripts](./source/register-active-tab-scripts.md) - Automatically inject scripts into tabs with `activeTab`

> [!NOTE]
> Firefox has some limitations:
> - `activeTab` seems to be lost after a reload
> - further `contextMenu` clicks receive a moz-extension URL rather than the current page’s URL
