With the culmination of several new releases and some updates the planets are finally aligning for a good experience for web developers with Site Studio. Fire Fox 3 has been available for some time. As noted on John Sim's Blog, the full release of Fire Bug 1.2.0 has also been announced. And to top it all off there has been an August Roll-up Release for Site Studio. (currently available only via MetaLink as far as I know and you can find it by searching for patches for 10.1.3.3.2 servers. You will have to log in.)
Now, when running in contributor mode in Fire Fox 3 things look pretty good. Prior to this release some of the images were off and some things did not work so hot.
