OS X 10.11.1 with Safari 9.0.1 freezes on opening new tab or address bar selection I've got MBPro Mid 2014 with the latest OS X update - 10.11.1. 

I have noticed that sometimes Safari freezes for 3-5 seconds when I open new tab or click on address bar. I am sure that I didn't have this issues few days ago.

In system logs I've found these entries which appear just after freeze occurs:

I've tried to clear Safari caches, delete cookies etc but to no avail.

Did anyone stumble across this problem?
I can't reproduce this issue. I guess it's related to incompatible Safari Extensions. Try disable them one by one. 

Moreover you should update Safari. Currently v9.0.2 is the latest Safari version. Open the AppStore > Updates > Update Safari
