This is an updated thread replacing the previous ones that have been archived. MX 7 and 6 only function on Windows 7 or later. Chrome 110 and later only function on Windows 10 and 11. Earlier versions of Windows will remain on Chrome 109. Chrome 110 and up function in the UA for all versions of Windows. At present (March 2023) it is not possible to change the User Agent in MX 6 using the traditional internal UA modifier/selector so you have to use extensions from the chrome store.
