Got a problem with my safari browser, javascript just stops running and have to close safari down to get it to work again. Runs fine again the stops working

ive manage to bring up the error console and it has the following.

Blocked script execution in 'http://www.metservice.com/_/files/social/content-stream.html' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

I'm completely lost when it comes to this kind of stuff and google hasn't really been of help

Does javascript stop working on every site your visit or is it just metservice? Does it happen if you open a new tab and bring up metservice again?

The error your seeing is used to stop cross site scripting. So this error is nothing to worry about.

it happens on a few other sites as well. haven't tried opening a new tab and trying but usually have 2 windows open with a few tabs on each, javascript won't run on any of them when it stops

hope that makes sense

Sounds like an odd issue. Maybe something is crashing the javascript runtime engine. Next time it happens in the URL bar type in javascript:alert("hello"); if a pop up appears saying hello then javascript is at least still working in some form.

Note that you'll need to enable JavaScript from the "Smart Search Field" (via the Develop menu) before that'll work.

Maybe try:

menu > preferences > extensions > off.

Then exit safari and try the same sites again.

Back when I was on osx I found it faster and more frequently updated than Safari.

By the way what version of Safari do you have?

Its the latest 9.1.2, Ive played with Chrome a little but preferred Safari probably because I was more familiar and like the setup

Its unlikely to do the same thing as they use different javascript engines. It sounds like something is crashing the javascript master VM's as it works when you open a new Tab it creates a new VM.

Worth a try next time it happens on a page that has stopped working type

javascript:alert("hello");

if that works then I just don't know but if not type

javascript:setTimeout(alert("hello"), 1);

as said before you will need to enable allow javascript from smart search field. Which will require enabling the develop menu which is found in preferences under advanced.

The reason for this is that the first command will run within the main DOM which should not run as it has crashed where as the second one will create a new thread in theory creating a new VM within the same tab so should work.

There should also be some crash logs. You should be able to find these under console which is in utilities in the application folder. May take a bit to find but they will likely have safari or webkit or event the name of the site that caused the crash.

Safari made some security related changes recently.

Maybe someone here can report if they get the same result for 9.1.2 with the metservice site. Could be metservice and a few others need to consider changes if Safari has changed.
