Either you can do as it says, and use C-u before opening the link, or
you can change the variable mm-w3m-safe-url-regexp:

,----[ C-h v mm-w3m-safe-url-regexp RET ]
| mm-w3m-safe-url-regexp is a variable defined in `mm-decode.el'.
| Its value is nil
| Original value was "\\`cid:"
| Documentation:
| Regexp matching URLs which are considered to be safe.
| Some HTML mails might contain a nasty trick used by spammers, using
| the <img> tag which is far more evil than the [Click Here!] button.
| It is most likely intended to check whether the ominous spam mail has

| that your email address is valid.  It is done by embedding an
| identifier string into a URL that you might automatically retrieve
| when displaying the image.  The default value is "\\`cid:" which only
| matches parts embedded to the Multipart/Related type MIME contents and
| Gnus will never connect to the spammer's site arbitrarily.  You may
| set this variable to nil if you consider all urls to be safe.

Maybe by setting browse-url-browser-function:

,----[ C-h v browse-url-browser-function RET ]
| browse-url-browser-function is a variable defined in `browse-url.el'.
| Its value is browse-url-firefox
| Original value was 
| browse-url-default-browser
|   This variable may be risky if used as a file-local variable.
| Documentation:
| Function to display the current buffer in a WWW browser.
| This is used by the `browse-url-at-point', `browse-url-at-mouse', and
| `browse-url-of-file' commands.
| If the value is not a function it should be a list of pairs
| (REGEXP . FUNCTION).  In this case the function called will be the one
| associated with the first REGEXP which matches the current URL.  The
| function is passed the URL and any other args of `browse-url'.  The last
| regexp should probably be "." to specify a default browser.
