Since a week or so my 2.2ghz MBP won't open certain websites regardless of what browser I use, I have tried Firefox, Safari and Opera without any luck. The thing is that all these pages work just fine on my old dell (on both IE and firefox) that uses the same wifi connection, so the connection is not the problem here it seems. The thing is that most websites work just fine, just a select few that have worked fine for months now suddenly have stopped loading and firefox saying it can't establish a connection with the server in question. Any ideas why this could be? Is it down to firewall settings? Browser settings or something else? All help very much appreciated, Thanks, P.s. one of the pages I cannot load is www.hsbc.com.hk Edit: I should probably add that I have tried with clearing out cache, cookies and browsing history without any effect.
