IE developer toolbar
The kids over at Microsoft have released an IE developer toolbar. It’s got most the nice things that the Firefox toolbar has like box outlining and options to disable scripts and cookies. One of the nice features it has that isn’t included in the firefox version is a little ruler tool that lets you measure the pixel size of the elements on the webpage.
I’m excited because I have to use IE for work, so this is definitely going on my work machine. I’ve been looking for a tool like this for ages!
