A few days ago any time I try to view a web page that contains some Flash,
Firefox (56.0) hangs for about a minute, then does something, and hangs
again for a minute, etc. Until I kill the tab for that web page.
Chrome works fine. Firefox used to work too, but now it doesn't.
Has anyone seen this?
PS. I had originally followed the instructions here to install Flash:
