Well, with
    Package: xul-ext-adblock-plus
    Depends: iceweasel (>= 3.6.13, << 12.0~a1+) | iceape (>= 2.1, << 2.9~a1+)
you could install xul-ext-adblock-plus as long as you have a compatible
version of iceweasel, even if you have an incompatible version of
iceape.

With the current implementation
    Package: xul-ext-adblock-plus
    Depends: iceweasel (>= 3.6.13) | iceape (>= 2.1)
    Breaks: iceweasel (>= 12.0~a1+), iceweasel (<< 3.6.13),
            iceape (>= 2.9~a1+), iceape (<< 2.1)
you cannot install xul-ext-adblock-plus if you have an incompatible
version of iceape, even if you have a compatible version of iceweasel.
Which is wrong.
