Microsoft also is making available a Blocker Toolkit for the new Edge for companies wishing to block the automatic deployment of the new Edge, as reported by ghacks.net. (The toolkit also can be run on Windows 10 Home systems by administrators.) The Blocker Toolkit won’t block the manual installation of the new Chromium-based Edge.
Microsoft officially opened the new Microsoft Edge Addons store to submissions to all developers on December 16. Devs can submit extensions via the Partner Center Developer Dashboard.
As Microsoft execs have said previously, in most cases, extensions built for Chromium should work without any modifications in the new Edge. Microsoft will no longer be accepting new extensions for the existing Microsoft Legacy Edge after December 17, 2019, but will continue to accept updates for existing Microsoft Edge Legacy extensions. The company is committing to migrate users’ extensions from Legacy Edge when they update to the new Edge starting January 15, but extensions will only be migrated if they’re already available in the Microsoft Edge Addons store at the time of switching to the new browser.
Microsoft announced in late 2018 that it was creating a new version of Edge by using Chromium combined with some components currently in Edge, all in the name of providing greater browsing compatibility across the web. Microsoft is using the underlying Chromium Blink rendering technology, but is replacing quite a few Chromium services with Microsoft equivalents.
Chromium is an open-source browser implementation that is used as a base by a number of browser developers, including Google (with its proprietary Chrome browser), Vivaldi, Opera, Yandex, Brave, and more. Simultaneous with the launch of Chrome in 2008, Google released the bulk of Chrome’s code as open source, birthing Chromium in the process.
In the ensuing months, Microsoft made Canary, Developer and Beta test versions of the new Edge available to users on Windows 7, 8.1, 10 and macOS. Microsoft also is working on an ARM 64-enabled version of Chromium Edge and a Linux version is likely, as well.
