Firefox added its 'Hello' videochat feature to its experimental beta browser back in October, and now it's taking on board user feedback to make it all a little more appealing. You can still use the feature without registering for the account, but there's now less steps to get that running - you'll also get an audio ping when your partner joins the call. Conversation windows each have a unique URL, which can be shared, well, anywhere you can paste it. You can then maintain these links to continue conversations at a later time and the message history will remain, even if you aren't registered for an account. So, what is the point of logging in with a Firefox account? It'll let you directly call you contacts - if they're also logged in.. and aren't using Hangouts instead.
