I hope this is the right place (I've chosen Accounts). When I ask a question, e.g. [https://support.mozilla.org/en-US/questions/1492818 this], on the right hand side there's a "'''Subscribe to feed'''" option with a feed link of https://support.mozilla.org/en-US/questions/1492818/feed When I insert that into my RSS reader, e.g. Feedbro on Firefox, the link isn't accepted. How does this ''Subscribe to feed ''work? (Image attached.) Thanks!
