Looks like I was using 'stable' instead of 'stretch' which may be
confusing: right now stable is stretch and I mean stretch when talking
about stable:

- firefox-esr/stretch and xul-ext-ublock-origin/stretch
- firefox/unstable and webext-ublock-origin/unstable (whatever unstable
  might be at the moment)

Now I see that it is not only Breaks:, but Replaces:
xul-ext-ublock-origin too.

(If not because of stable = stretch confusion) Sorry, but I don't
understand that - actively preventing two packages to coexist for no
real reason. I'm not an expert in Debian packaging, but 7.4. Conflicting
binary packages - Conflicts [1] seems as a perfect fit:

    Neither Breaks nor Conflicts should be used unless two packages
    cannot be installed at the same time or installing them both causes
    one of them to be broken or unusable. Having similar functionality
    or performing the same tasks as another package is not sufficient
    reason to declare Breaks or Conflicts with that package.

- webext-ublock-origin's files do not overlap with
  xul-ext-ublock-origin/stretch ones
- they do not break each other
- both firefox packages would ignore unsupported extension anyway

firefox/unstable does not Breaks: or Replaces: firefox-esr/stretch. At
the same time, webext-ublock-origin/unstable forces user to remove
xul-ext-ublock-origin/stretch.

webext-ublock-origin/unstable, as a new package since stretch, could
just not Breaks: and Replaces: xul-ext-ublock-origin.

What am I missing?

NB: keep in mind, non-native English speaker here ;-)
