How is it not working? What method(s) have you used? You can just copy-and-paste the URL into the message. You don't ''need'' to use the '''Insert|Link''' route. e.g. https://support.mozilla.org/en-US/questions/1059356?fpa=1#answer-preview If you don't want the URL text to appear, you could use the '''Insert|HTML''' option to create a formatted link: <a href="https://support.mozilla.org/en-US/questions/1059356?fpa=1#answer-preview">linky</a> which would look like this: [https://support.mozilla.org/en-US/questions/1059356?fpa=1#answer-preview linky]
