Error Unresponsive script
Help! I am using Firefox, and keep getting this warning on Duolingo. It usually says it is cloudfront, or a few others. I was getting it on other sites as well, but changing an antivirus setting helped on other sites, but I still get it all the time on Duolingo. Anyone have this problem before, and solve it? It is really frustrating in when I am looking in the discussions or looking for stuff in immersion.
