The sketchy meta-redirect previously used was no longer working with
Palemoon 28.5. This is an even more sketchy version that uses a
JavaScript redirect, but seems to work.
This redirect screws up the history, so this introduces a new bug as
well :/
My XPCOM-fu isn't quite good enough to figure out a nice way to
redirect a channel without this crap, so open to suggestions on a more
elegant way to solve this.
