Hi,

This is a bit of an oddball suggestion to say the least, but if you have a full proper install of Firefox that came from a package or repo somewhere, you might well have the changelog to look at. For example, on my own system (which is admittedly Ubuntu rather than RHEL/CentOS, but it's the only box I have Firefox installed on) I could do something like this:

Code:

zcat /usr/share/doc/firefox/changelog.Debian.gz | head -1 | awk '{print $2}' | sed s/[\(\)]//g

which returns:

Code:

51.0.1+build2-0ubuntu0.16.04.2

So if you have the changelog, you can look at the first line and strip out the version number, basically.

Other than that, if it was installed from a package you could query the rpm database directly, but since it seems you only have access to the files and not a running copy of the other OS build that might not be feasible. If it was installed properly via yum/rpm in the other OS though you could look at the yum.log or something similar, and strip out the version number that way maybe.

NAME

       dh_installchangelogs - install changelogs into package build directories

SYNOPSIS

       dh_installchangelogs [debhelperoptions] [-k] [-Xitem] [upstream]

DESCRIPTION

       dh_installchangelogs is a debhelper program that is responsible for installing changelogs into package build directories.

       An upstream changelog file may be specified as an option.

       If there is an upstream changelog file, it will be installed as usr/share/doc/package/changelog in the package build directory.

       If the upstream changelog is an html file (determined by file extension), it will be installed as usr/share/doc/package/changelog.html
       instead. If the html changelog is converted to plain text, that variant can be specified as a second upstream changelog file. When no plain
       text variant is specified, a short usr/share/doc/package/changelog is generated, pointing readers at the html changelog file.

FILES

       debian/changelog
       debian/NEWS
       debian/package.changelog
       debian/package.NEWS
	   Automatically installed into usr/share/doc/package/ in the package build directory.

	   Use the package specific name if package needs a different NEWS or changelog file.

	   The changelog file is installed with a name of changelog for native packages, and changelog.Debian for non-native packages.	The NEWS
	   file is always installed with a name of NEWS.Debian.

OPTIONS

       -k, --keep
	   Keep the original name of the upstream changelog. This will be accomplished by installing the upstream changelog as changelog, and
	   making a symlink from that to the original name of the changelog file. This can be useful if the upstream changelog has an unusual
	   name, or if other documentation in the package refers to the changelog file.

       -Xitem, --exclude=item
	   Exclude upstream changelog files that contain item anywhere in their filename from being installed.

       upstream
	   Install this file as the upstream changelog.
