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.
