Every now and then, Firefox (currently 50.0.2) locks up and does not respond. It actually locks up the system (Windows 7 SP1 Professional) and I have to “push the button” to restart. The Key Aviation Forum is loading a lot of “crap” in the background. This time it happened while getting data from “stat.comoona.com” or “stat.komoona.com” (spelling). Does Key och we really need all that “crap”, presumably related to advertising? It has come to the point where I don’t visit the forum while working with other programs.
