Currently DokuWiki produces a warning about wikilinks to Windows shares, saying that it will work only in IE.
It also work in Firefox, but it is DELIBERATEDLY DISABLED for good security reasons. However, it can be enabled, if you like to live dangerously. :-)
Actually, that it works in MISE is a security bug of MSIE.
To be more precise: not the windows shares, but the whole "file:" URL scheme is disabled, if the URL scheme of the referring page is not "file:" itself, that is, the file has NOT been obtained locally.
If the URL of the referring page starts with "file:", however, i.e., the page has been fetched from lcoal disk, then "file:" links work as intended with the default security settings.
Please refer to:
If you toggle the setting security.checkloaduri to 'false', then, voila, the windows-share-links starts to work in Firefox, too.
I suggest to modify the alert text accordingly.
