Wiki: 'Un-redirecting' a Redirect

[TheVeech]

Someone's slapped a redirect on the Firefox link:

https://help.ubuntu.com/community/Firefox

that I'm trying to use on this page:

https://help.ubuntu.com/community/Software

Can anyone let me know how to free this link up?  The information
contained in the redirect can still be included in the new page, so any
other pages linking to it would still have relevance.

TIA.
