Regardless if this is for a local installation using Chrome Desktop APIs, the phrasing "Hangouts won't work in your current browser" seems intentionally misleading.

Not providing a link for "browser" along side Android, iOS and Computer is terrible. Intentional or not I expect better from Google.
So what you're attempting to install here is a chrome app[1]. It uses the Chrome Extension/App APIs to create "desktop app" experience. Hangouts as a part of gmail/google+ I believe is supported on Google supported browsers[2].
Thanks for the clarification. The messaging is terribly misleading. I'm not claiming they are doing it on purpose but they aren't expending much effort to make it clear that you're installing a Chrome app that can't be installed on Firefox/Safari when they say "Hangouts won't work in your current browser".
Google+ Photo Editing has also gone Chrome-only: https://www.evernote.com/shard/s2/sh/776b19e1-487f-4dbb-9962...
