This is still driving me crazy. If it wasn't for using the integrated keychain across devices for passwords, I would have moved to Firefox and still might if I can't find a solution. Currently I have to quit safari a few times a day and use Firefox when Safari stalls on trying to load a page or stalls half way through a page. One site that this occurs on quite often is Chase.
What I've tried that doesn't seem to solve the issue...
-Disabling Limit IP Tracking in sys pref/networking
-Disabling Sophos Web Protection
-Disabling Malwarebytes
-Disabling LittleSnitch
-Disabling CleanMyMac
-Disable AdBlockPlus extension (although I haven't tried uninstalling it)
I can try using another admin account to see if I run into the problem but it's not easy given you never know when its going to start and can't just use a new empty account while working trying to make it occur. Same with Safe Mode. Given when I just quit and start safari the problem goes away, I don't know what I would learn in safe mode.
I'll probably try uninstalling extensions first. Then one by one uninstall some of the security apps even if disabling the various features doesn't seem to do anything. Not looking forward to doing that.
Frustrating
