We are looking to collect the home page of our users' Safari, Firefox, and Chrome browsers. We do not need to set the home pages, only to report the home page of each browser. This might a script, or a set of scripts (or scripts driving extension attributes).
The second part of this will be to report out the usage of each browser to determine the dominant browser on each system (assuming one user per system).
[edit] While our IT provides only the ESR version of Firefox, our users are allowed to grab whatever they wish, security withstanding.
[edit] A colleague has answered my question. Will post the script here soon.
