Probably.

You don't.  Dynamic IPs are on the blacklists because one can never know
who will be using them.  If you can't guarantee that you'll have that
address all the time, the blacklists aren't going to change.

Yes, but you're using Firefox.

I'm not terribly impressed with Firefox's filtering, but take a grain of
salt and consider that Firefox isn't meant to be ready to filter right off
the installation, you're supposed to train it.

I've been arguing against systems that automatically dump stuff in to
"trash" folders for two years now, Firefox not being the least of my
complaints ...
