현재 번역은 완벽하지 않습니다. 한국어로 문서 번역에 동참해주세요.

애드온들은 개발자들에게 Firefox의 기능을 변형하거나 확장하게 해 줍니다. 그것들은 표준 웹 기술인 JavaScript, HTML, CSS 또는 몇가지 전용 JavaScript API들을 사용하여 만들어집니다. 이러한 것들 사이에서, 애드온은 다음과 같은 일들을 할 수 있습니다 :

  • 특정 웹사이트의 내용 또는 모양새를 바꿉니다.
  • Firefox의 사용자 인터페이스를 변형합니다.
  • Firefox에 새로운 기능을 추가합니다.

애드온 개발하기

There are currently several toolsets for developing Firefox add-ons, but WebExtensions will become the standard by the end of 2017. The rest are expected to be deprecated over the same period of time.

Here you will find information about available options for developing add-ons, so you can make a decision on what’s best for you right now and in the future.

새 애드온 만들기

만일 당신이 새로운 애드온을 설계한다면, 우리는 아래의 두가지 방법들 중 하나를 고를 것을 추천드립니다. 웹확장기능들의 번역이 완전해질 때까지 각각의 방법들에 대한 찬반 여론들이 있을 것입니다. 아래의 선택사항들을 읽고 당신에게 알맞는 도구를 결정하세요.

기존 애드온(Add-on)으로부터의 이전

There are changes coming to Firefox in the next year that will make browsing more reliable for users, and creating add-ons easier for developers. Your add-on may require updating to maintain its compatibility, but once this is done and the transition is complete, your add-on will be more interoperable, secure, and future-proof than ever.

We've created resources, migration paths, office hours, and more, to ensure you have the support you need to get through the transition.

To get started, use the add-on compatibility checker to see if your add-on will be affected.

애드온 출시하기, commonly known as "AMO," is Mozilla's official site for developers to list add-ons, and for users to discover them. By uploading your add-on to AMO, you can participate in our community of users and creators, and find an audience for your add-on.

You are not required to list your add-on on AMO, but starting with Firefox 40, your code must be signed by Mozilla or users won't be able to install it.

For an overview of the process of publishing your add-on, see Signing and distributing your add-on.

애드온의 다양한 형태

Generally, when people speak of add-ons they're referring to extensions, but there are a few other add-on types that allow users to customize Firefox. Those add-ons include:

  • Lightweight themes are a simple way to provide limited customization for Firefox.
  • Mobile add-ons are add-ons for Firefox for Android. Note, though, that we intend to deprecate some of the technology underlying these APIs. In the future, WebExtensions will be fully supported on Firefox for Android.
  • Search engine plugins add new search engines to the browser's search bar.
  • User dictionaries are add-ons that let you spell-check in different languages.
  • Language packs are add-ons that let you have more languages available for the user interface of Firefox.
