What the hell is “Chromium Edge”???
Does it have anything to do with Gooogle Chrome?
https://en.wikipedia.org/wiki/Chromium_(web_browser)
Microsoft originally developed their Win10 "Edge" browser as proprietary in-house code. When it failed to attract serious use, they realized they'd be better off building Edge from open-source that was already the user standard. So "Chromium Edge" is an all-new "Edge" browser, built with the same code that Google developed for use in their Chrome browser.
It's a big deal that Microsoft decided that open-source was better than proprietary, in this situation. They also are making it available to non-Win10 platforms: Win7, Win8x, and even MacOS. This is another big deal.
