downloading, and not once it's loaded. I don't see why other tabs should
be affected in 7.0.1 / multiprocess at all. But it seems worse than the
6.0 series, not better.

> With "downloading" do you mean getting the external helper app dialog
and then downloading the file to disk or do you mean just loading the file
into your browser over the Internet? Do the two scenarios behave
differently for you?
Yes. I only see the issue when loading the file into the embedded PDF
viewer.
