@tsteur @Findus23 Not sure on that one, but do we still need to add rel="noreferrer noopener" to new links, or is that meanwhile covered by meta tags or headers?

noreferrer we wouldn't need anymore AFAIK. noopener is used by default in FF 79 https://bugzilla.mozilla.org/show_bug.cgi?id=1522083 , safari 68 https://webkit.org/blog/8475/release-notes-for-safari-technology-preview-68/ brave: brave/brave-browser#1840

Here's a detailed list of supported browsers: https://caniuse.com/mdn-html_elements_area_implicit_noopener

Seems maybe opera and android browser doesn't have this fixed yet and maybe still need it for a while? Also samsung browser only seems to have it since recently etc.

How does this get dealt with by white label plugin - i would like to reference my own guides.

Thanks for the question @craigvc, I haven't tested these links specifically with the white label plugin, but my understanding is that any links to matomo.org should be automatically removed. Unfortunately there isn't any capability to add your own links at the moment.
