My day to day work consists of a lot of time spending on the internet, looking at web presences of current clients, prospective clients and their (and our) competition. My tool of the trade being FireFox 3 (especially considering that IE seems to have a little problem). I am using a number of addons which really help my work-flow in the fields of usability, accessibility, SEO and occasionally information architecture.
I was asked by a couple of fellow twitter users to divulge my plugin list, and since I keep track of them myself at times I thought this post would come in handy for everyone.
