However, nearly 5,000 add-ons are already available using the new APIs, including Tree Style Tab, Tab Center Redux, and uBlock Origin. For example, the new APIs do not offer the degree of UI modification necessary to support Classic Theme Restorer. Unfortunately, the impending removal of old APIs with next month’s general release of Firefox Quantum will necessarily end support for several legacy add-ons. Since many WebExtension APIs are compatible with Chrome, Edge, and Opera, popular add-ons from other browsers (like the Vue.js DevTools) can run on Firefox without significant modification.

You can find the source code for the debugger on GitHub. You can read all about the current and upcoming features in Julian Descottes’s article, but we’re especially proud of our completely new debugger: as part of the “ devtools.html” project, we completely rewrote the debugger as a modern web application, powered by React / Redux, and using standard HTML, JavaScript, and CSS. We’ve also put an enormous amount of effort into Firefox’s Developer Tools. This is remarkably useful for automated testing, both during local development and as part of a continuous integration (CI) pipeline.

Second, Firefox is now 64-bit by default on all operating systems, and existing 32-bit installations will automatically upgrade to 64-bit builds if supported by the underlying hardware. For example, you can right-click on any node in the Inspector to capture a screenshot of that node, or you can use the screenshot command in the Developer Toolbar. Of course, the Developer Tools retain their own screenshot capabilities. The tool makes it easy to select regions of the page based on the underlying DOM structure, though both full-page and free-form screenshots are also available. What about last week’s release of Firefox 56? Browser Featuresįor users, Firefox 56 sports two major changes:įirst, Firefox Screenshots is a brand new, built-in tool for capturing and (optionally) sharing images of web pages. Here at Mozilla, we’re extremely excited about next month’s release of Firefox Quantum ( preview it today in Developer Edition!) which brings massive speed improvements, a brand new UI, and several new or improved Developer Tools.īut that’s next month.
