The version of Firefox ESR that is provided is version 31.3.0. Before even trying to debug these things, you should try updating to the recent version. There are many security holes in the version you are running, as well. I have to wonder what other packages are out of date, such as openssl. Your pings against www.opera.com and opera.com aren't unusual. Not all hosts respond to pings. I can confirm that behavior on my systems. I suggest keeping your system up to date before trying to track down whatever problems you're having. -- Jonathan Billings <billings at negate.org>
