Reposted with permission from Jan Odvarko (AKA Honza): I have been recently asked by couple of developers how to properly design architecture of a Firefox extension. The first thing that immediately came to my mind at that point was a problem with global variables defined by extensions in ChromeWindow scope. This problem can easily cause collisions among various extensions. Something that should b
Here you should find a set of useful code snippets to help you work with Firefox's tabbed browser. The comments normally mark where you should be inserting your own code. Each snippet normally includes some code to run at initialization, these are best run using a load listener. These snippets assume they are run in the context of a browser window. If you need to work with tabs from a non-browser
Support for extensions using XUL/XPCOM or the Add-on SDK was removed in Firefox 57, released November 2017. As there is no supported version of Firefox enabling these technologies, this page will be removed by December 2020. Add-ons using the techniques described in this document are considered a legacy technology in Firefox. Don't use these techniques to develop new add-ons. Use WebExtensions ins

Among other things, an add-on could: Change the appearance or content of particular websites Modify the Firefox user interface Add new features to Firefox There are several types of add-ons, but the most comm

Mozillaは米国時間1月19日、ブラウザ内コマンドラインツールのような拡張機能「Ubiquity」の最新版を発表した。機能強化の多くは「安定性」の改善を目的としたものだが、外観もダークカラーに大きく改善されている。シンプルなCSSを利用した新しいスタイリングシステムにより、誰でも概観を変更できるようになった。製品が成熟するにつれ、ユーザーがデザインしたテーマがアドオンサイトに加わるかもしれない。 新版では外観を一新したことに加え、「Firefox 3」の「awesome bar」と同じ技術が取り入れられている。これはユーザーが過去に利用したコマンドの一部を記憶する技術で、コマンドの入力にかかる手間を省いてくれる。たとえば、Ubiquityに元から入っている、Wikipedia内検索の機能を頻繁に利用する人は、Ubiquityで「w」と入力すれば、頻繁に利用するオプションとしてこの拡張機
