Dutch Prases, Lesson 5 freezes
I'm using Ubuntu 16.04.1 LTS and Firefox 48.0.
When I try to complete Dutch Prases, Lesson 5, and I reach the question:
Translate this text "Hello, how are you? Fine, thanks."
After I click "Check", I get a message that a script may be busy or may have stopped responding. I can't complete the lesson.
I entered a bug report about this over two weeks ago. Should I stop asking about this? Should I not expect to be able to do the Dutch course with my browser/OS? If not, how long can I expect to wait?
