I try to download from microsoft store, I get this message

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (ms-windows-store) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

Hi jertigger2222, could you take a look at the following preference:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste ms-w and pause while the list is filtered

(3) If the network.protocol-handler.external.ms-windows-store preference is bolded and has a value of false, double-click it to restore the default value of true

The goal is either to get the ms-windows-store: URL to launch directly into the Windows 10 Store app, or at least to give you a choice of how to handle it.
