I've been testing/evaluating the new Edge since April 2019, first on Win10, then Android, then iOS. Microsoft has done a good job of unGoogling the browser, and I'm satisfied that the Edge offers a reasonable level of privacy within the Microsoft ecosystem. Edge is still something of a work in progress, but all the basics are in place in the Win10, Android and iOS Stable builds, and I assume that Edge on Linux will get to that point in a matter of months.
I've been using Firefox as my primary browser for 15+ years but am willing to consider moving to Edge if and when a stable release is available on Solus. However, because my Solus install is a production install, I'm not interested in using any apps (including Edge) that Solus does not include in the repository. I've noticed that Solus includes various browsers (including Stable, Dev and Canary versions of Chrome) in the 3rd Party repository. Does anyone know whether Solus has any plans to do so with Edge?
