When going to use Adobe express on Firefox it comes up with the following message, saying that this browser doesn't play well with others and that I should use Safari, Google Chrome, or Microsoft Edge instead.
As someone that is the manager of a web app for a FANG company, it’s not easy to support everything. Right now we don’t support Firefox because the APIs we use (and don’t own) don’t support it. To enable support is then dependent on those other companies/teams to add support which can sometimes be years to develop. Chrome is easier to support because it’s based on Safari and so many other browsers use it as well.
