Interestingly, Chromium also underpins the dominant Chrome browser, but Google has yet to bring its browser to the Microsoft Store.

With the July policy update, both Chromium and Gecko (Firefox's browser engine) are permitted within the Microsoft Store. In addition, before July 2021, Microsoft prevented browsers using an independent engine from appearing in the Microsoft Store. 'Previously, if you were on Windows and wanted to use Firefox, you had to download it from the internet and go through a clunky process from Microsoft,' said Mozilla in a statement.

However, the two companies seem to have buried the hatchet with this latest move. Mozilla has played a sort of cat and mouse game with Microsoft in the past, particularly when it comes to default browser shenanigans in Windows 11. Mozilla's Firefox browser just achieved a milestone today: It became the first 'major' web browser to make its way to the Microsoft Store (opens in new tab) for both the Windows 10 and Windows 11 operating systems.
