Downloading files causes the browser to hang my system for 10 seconds

@UltrafineIncorporate,
Can you please try downloading a file from within a Guest profile so we can check and see if the issue occurs in a fresh profile as well? If the issue is intermittent it could be tricky, but I would suggest you:

  1. Browse normally on your main profile
  2. When you try to download something and notice the issue, go ahead and open a Guest profile window (Menu --> More tools --> Guest profile) and close your main profile window
  3. Then, try to go a d download that same file using the guest profile window

Check to see if the issue reproduces there.
