Firefox ExtendedSupport:Proposal
I had hopes that a long term support version would be available for BSD desktop users, it looks like the binaries will be Linux, OS/X and Windows specific and the source will still have to be cranked out by a maintainer.
I might also be doable by a user modified port. One could update the Mozillalongterm<dot> version in ports by copying the port and editing the version along with the checksums and crank out your own update. I wonder if the port maintainers will look at this?
