Rated 4 out of 5 stars
I've missed this addon since it became outdated I think when 3.6 came out.
I think this addon does a great job, but I have the same gripe as Aurora does. I find that you can close the tab by either clicking the X or Ctrl+W, but if the Downloads tab is the only tab open, Ctrl+W will closes the entire window.
If you could please amend this issue, this addon will be perfect!
