What are some browser "distributions" (a la linux distributions) that are pre-configured for web development? I'm thinking for example of an OSX app I can download that contains Firefox already configured with the most popular web development FF plugins)
In my opinion, Firefox, Chrome and Safari already has sophisticate development tools with default distribution. Chrome has
Web Developer. So plugin such as Web developer become a handy tool from an essential element for web development like the old days. Many other plugins are personal preference and task specific such as automated testing.
