Mozilla has released Firefox 41 for desktop and Android users, the company says that this is the first web browser that features a built-in instant messenger. It’s called Firefox Hello Beta, Mozilla developed it in partnership with Telefonica, and it lets users send and receive instant messages when they’re in a video call in Firefox for Windows, Mac and Linux.
This sounds like a good feature for people who want to chat, but not have another program or website tab open to use another instant messenger like Skype, YIM, and AIM.
Maybe uninstalling Firefox, and re-installing Firefox 41 will add the feature. You may have also remove the Chat bubble button from your Address Bar Navigation Toolbar in Firefox 41.
