[pmwiki-users] RFC: Adding rel="noreferrer" to external links

[Petko Yotov]

There is a request to add the "noreferrer" keyword to the external link 
HTML template.

   https://www.pmwiki.org/wiki/PITS/01520


What rel="noreferrer" does

The rel="noreferrer" attribute prevents the browser from sending the 
referring page's URL to the linked website. It also disables the 
window.opener property for security.

Benefits of Changing the Default:

- Privacy: Users' browsing history is not shared with external sites.

- Security: Prevents external sites from manipulating the original page 
using window.opener.

Drawbacks of Changing the Default

- Loss of referral data: External sites cannot see where visitors came 
from.

- May affect affiliate links: Some tracking systems rely on referral 
data.


This can be easily added or removed by a wiki administrator by 
redefining $UrlLinkFmt, but currently, it is not enabled. The feature 
request asks for it to be enabled by default.

What do you think? Should this change be made? You can join the
