Thanks both for the answers.
I thought that the exclamation mark means “important”, similar to userchrome.css !important; tag. ^____^
Anyway, a real case is:

www.hwupgrade.it##.form-offerte
but, according with these new “revelations”, it seems I have do some more test!
besides it seems the filter started to work again after I modified the first line.
PS: I forgot to say that I mainly use FF52ESR, but I’m quite sure the problem appears in my other FF57 installation too.
EDIT:
Maybe I didn’t focus the real problem. Let’s try with another example.
I’ve this filter, it works fine:
! 29/11/2017, 16:06:54 http://www.hwupgrade.it/news/
www.hwupgrade.it##.page-content > div:nth-of-type(3)
It works too fine to say the truth, because it hides an element it should not be hidden in a different page that is covered (but should not) by a filter.
I need that the filter works on “www.hwupgrade.it/news/
” and not in the whole “www.hwupgrade.it/
”. Something like:
! 29/11/2017, 16:06:54 http://www.hwupgrade.it/news/
www.hwupgrade.it/news##.page-content > div:nth-of-type(3)
but it don’t works. Is there somewhere a syntax manual for ublock?
