[FairfieldLife] OT: how to set default.mime parts on_demand in thunderbird?

[It's just a ride]

In windows.

If wishes were fishes,
I would be tuna in a can
my good luck left and ran
it was stolen by the man
stick it to the man
lock him in a van
crash it in the sand
luck will return to my command
a pebble in my hand
