List of strengthened words does not show up

After I complete a lesson, I should get a list of strengthened words. But the animated list of words does not appear and button "Continue" does not work.

Can you check to see what extensions/plugins you have installed? Delete any that aren't necessary. Our team took a look, but can't see any issues on our side.

thanks for checking it.
I have installed a new Chromium without any extensions and DuoLingo works perfectly now.

Perfect!
