To open Agrimaster you must change your default browser to Microsoft Edge or Google Chrome.
In order to make our software as widely accessible as possible, we have standardised on the two biggest browsers in the worlds.
Agrimaster 6.5.0 is not compatible with Firefox at this time as every single browser has a slightly different interpretation of browser standards. Opening Agrimaster on Firefox is like trying to fit a John Deere part into a Chaser. It is not compatible.
