I believe that this is what placing a package on "hold" does.  The
debian faq describes the "hold" status as:

    * hold - the user wants this package not to be processed, i.e., he
      wants to keep the current version with the current status
      whatever that is.

    6.12. How do I put a package on hold?

         There are two ways of holding back packages, with dpkg, or with

         With dpkg, you just have to export the list of package selections,

              dpkg --get-selections \* > selections.txt

         Then edit the resulting file `selections.txt', change the line
         containing the package you wish to hold, e.g.  `libc6', from this:

              libc6                                           install

         to this:

              libc6                                           hold

         Save the file, and reload it into dpkg database with:

              dpkg --set-selections < selections.txt

         With dselect, you just have to enter the [S]elect screen, find the
         package you wish to hold in its present state, and press the `=' key
         (or `H').  The changes will go live immediately after you exit the
         [S]elect screen.

You mean use chattr to set the filesystem's immutable flag on the
executable?  I don't think that would be a good idea because dpkg would
probably crash out with errors when it noticed that the package wasn't
unpacking properly.  It might work, but I suspect you'd get a lot of

One option to consider is to just uninstall the mozilla package and
build from source without worrying about creating a new debian package.
You could download the source from mozilla.org or take it from mozilla's
source package under debian.  That way, apt-get will never step on your
version of mozilla (and even if you did accidentally reinstall the
mozilla package, your custom build would probably be safe in
/usr/local).  The only real problem with this solution is if you have
packages that depend on the mozilla package...
