Cannot start a link from within a newsfeed anymore

[Hermann]

Hi,
since upgrade to Emacs 23.x I get difficaulties in using the internal w3m
as HTML/feed viewer.
Not only that there appear character encoding conflicts for German -
umlauts are not shown correctly - but I cannot open external links from
within feeds/blogs.
At the end of a blog/feed entry, you see the word "link", and if I click
on this word, i get the message:
"This link is to be considdered unsafe; use the prefix arg to open it
anyway."
What does this mean, and how can I fix this issue?
Hermann
