Anyone else noticed that when opening an existing thread, a delay in loading as "connect.facebook.net" is contacted (as indicated by the activity window at the lower left of your browser window)? I've been seeing some 10-15 second delays today!
OK, it seems that connect.facebook.net is a social media tracking site. I installed https://disconnect.me/ (free version) and the delay seems to be gone. Don't want or need to be tracked, especially if it interferes with page loading!
