Dear TW/i586 users and hackers,

The latest submission of Firefox that reached Factory unfortunately
declates i586 as an excluded arch. The build fails on this

This means unless somebody steps up and helps the Firefox maintainer
with relevant fixes to get this back in shape, there won't be a Firefox
build left for i586 users.

I hope there will be somebody around to help out and keep this alive.

FWIW, it builds on Debian unstable on i686, so in general, it should be possible.
