## What it is
A curated list of resources for developing WebExtensions, the cross-browser extension API system. It collects documentation, libraries, tools, testing resources, boilerplates, and sample extensions for building browser add-ons.

## Use cases
- find libraries for building a browser extension
- learn how to develop cross-browser WebExtensions
- find boilerplates to start a Chrome or Firefox extension
- discover testing tools for browser extensions
- port a Chrome extension to Firefox
- find sample extensions to learn from

## When to choose
- you are starting browser extension development and need curated resources
- you want libraries, tools, or boilerplates for WebExtensions
- you need documentation links for Chrome, Firefox, Edge, Opera, or Safari extensions

## When to avoid
- you need a runnable tool or framework rather than a list of links
- you are building native desktop or mobile apps unrelated to browser extensions
- you need Safari-specific extension resources, which are only partially covered

## Facets
- artifact type: learning-resource

- function: developer-tools, documentation
- domain: browser-extensions, web-development, developer-tools, awesome-lists
