I have been extremely frustrated lately with the web content quitting & re-opening arbitrarily, in Safari 10.1.10, and often when I'm in the middle, or just about to finish writing a long message or comment! This is ridiculous, as I can easily force-quit it myself, when I determine Safari is slowing down too much, I have no idea what triggers it doing it on its own, as it occurs when Safari is operating just fine!


Who's great idea was this, to take all control away from the user?

    There are accompanying crashes shown in Console or ~/Library/Logs/DiagnosticReports/ here - none for you ?


    I've not tied it to particular sites and/or extensions so far.

    Saxman --


    You've been having problems with Safari for a really long time.  It really should not be happening to you.  I'm thinking it's an extra Internet  "add on" that's causing the problem.  There's a great little app that a fellow ACS expert has developed that I think might hep us identify the culprit.  It's free, and I can vouch for it's safety:



    If you download that app, and copy and paste the results, it should get us way further towards getting to a final solution.

    I have exactly the same problem since upgrading to IOS 7, but I have only been been given simple and rather stupid advices frióm support. The problem however seems to be more frequent on a specific web site,


    Apple web pages seems to be working OK. The Safari shut downs/re-starts is extremly annoying!!!!

    Saxman, You have a lot of third-party stuff installed, one of which is near-fatal to Safari.


    SIMBL is worst:


    [loaded] net.culater.SIMBL.Agent.plist

    This one shows up in a lot of crash repeorts:



    Programs that claim to clean your Mac are largely troublemakers:


         [loaded] com.freemacsoft.appcleanerd.plist


    There is so much like this on your computer that I think it wise to practically start over with Safari and NOT load it or you system with third-party cr@p.


    I am going to have to call Apple myself and complain about this one,


    When you call, be sure to tell them you've installed a large quantity of third-party garbage. What you have done is like buying a Ford and then yelling at them after you install a bunch of Chevy parts that cause the Ford to run poorly.


    Safari runs like a charm me and my family (about 18 Macs among the five of us) and always has becasuse I've never installed more than the bare minimum of extensions.

    Hear, hear!

    We have a start. Please run Etrecheck again so we can see if something is dodging your attempts to rid yourself of the pesky components.

    Well, most of these programs are not anything I voluntarily installed, and so don't really know what they even are, much less how they got in there.


    Good to know. Some of these troublemakers are hidden in pop-ups or bundled with something you needed to download. Let's work through it and maybe we can then figure out how they got there.


    I've seen similar situations where the owner of the computer would never allow that stuff in, recognizing cautions the OS throws up, but find bad stuff anyway after their brother-in-law or a grandkid was on their computer. Poo happens--lets see if we can scoop it up!
