Greetings! For the FDM browser addon to function correctly, you need to install the Free Download Manager software. You can obtain the most recent version on the official site. If you encounter any other issues, please feel free to contact our support team through this form: https://www.freedownloadmanager.org/support.htm. As for the anonimous data usage notification, we assure you that the FDM extension only transfers data necessary to launch downloads into the FDM client, just as it did before. The recent notifications were implemented solely to meet Mozilla's requirements. We value your privacy and are transparent about data usage.
