qbrt

As I understand it, Gecko is much harder to work with, so it would take a lot of time to make something like brave compatible with both Chromium and Gecko/Firefox's APIs (or to even only move to Gecko/FF). See the following comment from [0]: > More significantly, in my book: it’s difficult to use Gecko and Firefox in these ways. Even the simplest app requires substantial and arcane boilerplate. And the docs are comprehensive but outdated. The platform may be powerful, but it’s hard to use. There's also now qbrt[1], but the readme itself recommends not using it, and it was last updated 7 months ago. If this matures to a usable state, I can see Brave developers considering it. 0: https://mykzilla.org/2017/03/08/positron-discontinued/ 1: https://github.com/mozilla/qbrt

Originally, there was XULRunner, which was used in applications including ChatZilla, Google AdWords Editor, Komodo Edit, Pencil, Songbird, and Zotero. XULRunner has been discontinued. https://developer.mozilla.org/en-US/docs/Archive/Mozilla/XUL... Mozilla briefly developed Positron, which was an Electron-compatible app shell that used Gecko instead of Chromium/Node.js/V8. Positron has also been discontinued. https://github.com/mozilla/positron The developer who was working on Positron went on to develop qbrt, which is a CLI interface to a Gecko app runtime. The project is unstable, and the last commit date is Jun 30, 2018. https://github.com/mozilla/qbrt Another Mozilla developer has a project called servoshell, which is an embeddable version of Servo. It's described as work-in-progress, and the last commit date is Jan 7, 2018. https://gi
