Losing progress upon Ctrl+clicking a link at the top
I was in the middle of a lesson and wanted to know something on Duolingo. I held Ctrl and clicked the lingot. It took me to what I wanted, but in the current tab, and when I went back the lesson started over.
There are really 2 issues: (1) Clicking Duolingo links in a lesson destroys progress in the lesson, and (2) Ctrl+clicking Duolingo links opens them in the current tab, not a new one
