Microsoft Edge based Chromium has already been popularized by Firefox, mainly because the browser is lightweight and offers better performance/features. In Edge Canary, Microsoft is currently testing Office integration to help users access Microsoft 365 apps directly from the Edge menu.
Microsoft Edge's right-click menu or the context menu for its tabsletterbrowser will include a new option called “New Office Tab”. As the name suggests, this Edge option will allow users to open online Microsoft Office applications such as Word, PowerPoint, and Excel.
It also appears that the new Office integration will not be exclusive to Microsoft 365 subscribers, so you will be able to access a regular Microsoft account.
But in addition to integrating Office, Microsoft suddenly decided to display advertisements within Microsoft Edge. After recent updates, some users are seeing more alerts and advertisements for company services such as Microsoft Start (a rebranded MSN).
As you can see in the image above, Microsoft is experimenting with more ads to appear on the page of each new browser tab.
Fortunately, you can close these pop-ups by pressing the "X", but that doesn't stop Microsoft from serving other ads in the future.
