Edge is Only at 4% Market Share Despite All Its Pestering. This isn’t the only message in Windows 10 that promotes Microsoft Edge. For example, even after you install Chrome or Firefox, the Settings dialog won’t let you make either your default browser without asking you to check out Edge first. Nov 02, 2020 Around February 2020, something odd happened. For years, Chrome and Firefox had been comfy as the top two browsers on the market. Then, Firefox was taken off its number two spot by Microsoft Edge after it adopted a Chromium base. At the time, it was hard to tell if Microsoft Edge would hold its position. Microsoft is heavily pushing their Windows 10-exclusive browser, Edge. Ads built into Windows 10 are now claiming that Edge is “safer” than Chrome and Firefox.
