Re: I'd love to try Waterfox, but there's a problem...
I sometimes do the build from source option, at least when you are NOT in a hurry and there are no ports/packages available. But depending on your setup, it may take more work than you want to put into it (like manually loading dependencies and source/dev packages on most Linux platforms).
If there are no install instructions, are there at least BUILD instructions for Waterfox? (I see no FreeBSD port for it, either).
