is it possible to decorate a package build, i.e. set some prconditions

E.g., to modify the firefox package update to first compile with
"--enable-alsa". Of course, I would have to create my own package in a
private repository. The new PKGBUILD file would need to refer the
original one, to get e.g. the package version number. However, the
private package would always have the same version, so the official
package change needs to be hooked to the generic private package:
Official Package Changed --«Signal»--> Private Package Update
--«Inherits»--> Official Package Update
This isn't worth the effort, however...
1. disable updating the firefox package:
/etc/pacman.conf
IgnorePkg = firefox
2. write a wrapper for pacman that first compares the installed
version, with the version provided by the repositories
pacman -Q firefox | cut -d\ -f2
pacman -Si firefox | grep Version | cut -d: -f2
3. use the sed command, so that the wrapper could edit the version
mentioned by your PKGBUILD
4. let the wrapper build and install your package
5. let the wrapper run a regular "pacman" with $@ options
IMO it's easier to use apulse-git and if you should use freedesktop.org
menus, to edit a desktop file to launch "apulse firefox" by a sript.

Thank You! However, while one part is about Firefox, the other is about
changing builds while still getting the signalling for new builds from
pacman.
One possibility seems to use Hooks, while I'm not yet sure how to use
them correctly.
