Thanks for the info. I totally forgot Hangouts was still using an NPAPI plugin, and I didn't realize Firefox dropped support for those too. Doesn't explain why Safari wouldn't be supported though, as Safari still supports NPAPI plugins.

I haven't tested Safari, but Hangouts' system requirements say it supports Safari and IE using the NPAPI plugin:
