I am using the Firefox Nightly version and when I click on links related to Instagram, YouTube or other applications, it takes me directly to the application. But when I click on the my course link, it directs me directly to Microsoft's own site to download the application. (Microsoft Teams) I tried this in other browsers, but they did not have such a problem. That's why I downloaded and tried other Firefox versions, but they also have the same problem... I also disabled the extensions but the problem is the same. So the problem is, while Firefox Nightly opens other sites in the application, it does not open it in the application when i click on this course link. What is the source of the problem? Thanks, best regards.
