I have a new 2017 tMBP. For the past week or so, pages (pretty much all pages) have been hanging (often for +/-10 seconds!) before loading and running normally. I had Ghostery running, and tried turning that off - no difference. I noticed the Safari update today and got that - no difference. I uninstalled Ghostery and got adguard instead - no difference. I thought maybe it was my internet connection, but I had to use Chrome for a few things and noticed that there's no hang at all on Chrome. Any ideas, or steps I can take for diagnosing a solution? Thanks.
