At work I have been frustrated by the corporate IT security policies. Everything is monitored. They are Microsoft-centric. https traffic seems to get pushed through a proxy. All pretty standard really. I have been running portable Firefox as my preferred browser until last week. It all came to an end when I found an anonymous post-it note with the short message, 'We will win'. Looks like the proxy is now enforced and I have to go back to the corporate browser. I had not realised I was in any kind of competition, until now.
