Firefox Scratchpad Runs in the Context of Active Tab
Ideally it would be awesome for these code snippets to be saved in the cloud or work with a 3rd party service like jsFiddle to share with other web developers and team members.
I am really looking foward to the renewed support for developers in Firefox and am excited that they have an agressive schedule for getting new features in the hands of web developers and users. The new Firefox Scratchpad has me doing more development in Firefox so there is always a chance I may move from Chrome to Firefox as my web development browser of choice. Maybe.
