No Download_Computer says "The address wasn’t understood"

Having trouble with LMMS? Ask about it here.
Hello there

when i try to open the link for the download my computer shows me this

"The address wasn’t understood

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

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

i tried to use this terminal thing as well but my computer tells me it doenst know this command.
Does somebody know which software I am missing? Or what else i could do?

thanks a lot

a btw i have manjaro linux...if this is any help and i have no idea about this programm or any other
i made it!!!!!!! yeaaaah
Can you tell us what link you're trying to open ?

I do not know manjaro in detail, but most modern Linux distro's have firefox installed out of the box.

Apt sounds debian based.

Edit congratz.
