I've sent a patch that fixes these issues. Now we have the supported
version, that is installed by installer, and 'known to work' versions,
that are checked while searching the installation. Strings are enough to
identify the version. We have only a short list (currently one, two will
be soon) of versions to check. The compatibility with older version will
get worse in the future and someday we may decide to remove older
version from the list (by then most users will probably have newer Gecko
installed). As each Gecko version is installed in a different location
and in target location we expect specific version, I've changed the
version check in the loading code to fail if it finds an unexpected
version. It will probably be a good idea to add an option to identify a
Gecko installation that is not checked against versions to make testing
different Geckos easier.
I hope it is an acceptable solution.
