When answering a question, is there any way to turn the string "about:config" into a hyperlink that will open exactly that ("about:config", a feature of Mozilla applications) when clicked on?

It seems that "http://" is required at the beginning of a hyperlink for it to be recognized as such. Is that correct?

It doesn't look like that link will work anyway, probably a security feature of Firefox:


<a href="about:config">about:config</a>

If that worked, you could have cheated and used a service like tinyurl to get around the markdown "bug":


  • I can't get markdown to link to about:blank though...

  • You're right, it appears as a hyperlink at jsbin but nothing happens when I click on it. I thought it would work because kb.mozillazine.org/About%3aconfig have a bunch of them which I can click and the correct page would open...but I just now realized they're being turned into links automatically by the Linkification Firefox addon I have installed (and completely forgot about).

  • Interestingly, such a link seems to work when you right click and open in a new window/tab.
