April’s big news was the public preview of the first Edge browser that uses the Chromium rendering engine. If this seems like a minor footnote in history, it at least marks a turning point in browser development by Microsoft. Instead of continuing with the Edge browser on Windows 10 using its own EdgeHTML rendering engine (and all the potential compatibility headaches and support issues that may entail), the team decided to move to using the open-source Chromium engine that underpins Google’s Chrome, and to make Edge available on older versions of Windows as well as the Mac.
After early builds were leaked, the Edge team has been working to release the preview in daily (“Canary”) builds, or weekly (“Developer”) versions. They can be side-loaded alongside both the regular Edge browser and Chrome, so giving it a try is a fairly low risk activity, and in unscientific comparison tests it appears to be as fast or slightly faster than both Chrome and the other Edge.
Check out more info on the Edge Dev blog, and get the latest build from the Edge Insider site. The Chromium-based Edge (already being referred to as “Edgium” by some) will support addins built for Chrome, though for now, just a subset are available from the Microsoft Store, and many more will follow and it is possible to add others.
In time, most (though not all, it seems) of the features that have been built into Edge will migrate to the new version, but for now, the test builds that are being made public look a lot like Chrome in places – eg. the settings menu, that takes place inside a browser tab rather than a sidebar, like “Classic” Edge.
Other oddities include shortcut keys – in old Edge, CTRL+SHIFT+P will launch an InPrivate window (useful for logging into Azure portal or Office365 admin page using different creds … what else?) but in both Chrome and the Edge Dev build, that launches the print dialog, and Incognito/InPrivate is CTRL+SHIFT+N.
