Iceweasel is a Firefox derivative.
I know, and I was not suggesting adding it to Trisquel. As I said, I was
using it as an example that it does not have to be a free software issue for
it to be addressed (as a response to Mason's comment).
FallbackDNS must be defined to nothing to really not have a fallback
I understand now and have not tested it. I suppose if the maintainer says so
then that would be the safest bet apart from testing.
So, well, it is not a grave problem
I've followed the whole discussion on the Debian bug report since '14. It is
not as grave as many other things, though I am amazed at the intransigence
and tone taken by a few on the "it's not a bug, it's a feature" camp.
