I'm using Chrome on 10.9.4 on a MacBook Air from mid 2011. Updated to 10.9.4 yesterday and now I can't get more than 4 tabs to connect to web sites using Chrome. All others time out with "No data received." Bringing up Safari, I can reach no sites at all. Any thoughts? added note: This is ONLY on my MBA. I have this MacBook Pro and a mini, plus a couple of iPads with no issues, so it is something on the MBA.
