MacOS – 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:

24/10/15 21:26:48,048 PressAndHold[334]: IMKServer Stall detected, *please Report* your user scenario attaching a spindump (or sysdiagnose) that captures the problem - (activateServer) block performed very slowly (2.02 secs)

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

Did anyone stumble across this problem?
