How comfortable are native Luxembourgish speakers speaking German?

[u/david_fire_vollie]

I understand they don't like French very much, have an accent when they speak French, and are taught in French at school when they're older.
But with German, it's very similar to Luxembourgish and it's the langage (Reddit won't let me spell it correctly) of instruction when they start school, at a time where the mind is more easily able to pick up foreign languages.
With these comibned, does this mean German is like a second mother tongue for the natives?
