Believe it or not, the popular Mozilla Firefox web browser has hit the 50.0 milestone, and we have to admit that we expected to see some major features and improvements, but that didn’t happen. The biggest new feature of the Firefox 50.0 release appears to be emoji for everyone. That’s right, the web browser now ships with built-in emoji for GNU/Linux distributions, as well as other operating systems that don’t include native emoji fonts by default, such as Windows 8.0 and previous versions. Also new, Firefox 50.0 now shows lock icon strikethrough for web pages that offer insecure password fields.
