I sometime notice this random behaviour of the bookmarks not closing and it leaves me with something like this, any suggestions?

I'm running Mavericks with everything updated. enter image description here

  • is the extreme 'squariness' the symptom, or anonymising for the picture?

  • @Tetsujin it's anonymising =) the problem is the grey area that keeps showing until you open and close the bookmarks again. Commented Dec 18, 2014 at 19:56
  • OK, thanks, just checking. Does it do it immediately after a reboot? Have you tried with very few tabs open? [I know how many tabs you can build up over a time… & they really hit memory] My thought is it could be struggling for memory, paging to disk etc.

  • To be honest it's not slow and safari uses max 500 mb memory. I think it happens more at random. Commented Dec 18, 2014 at 20:47

I think you might be surprised how much memory Safari can use if you view all its processes Hierarchically… a rough tot-up here gives me about 2.7 GB ...
