Yes. "View source" being in pretty much every browser from the beginning has been an important part of the democratizing nature of the web. As web sites and development have gotten more complex, have dev tools baked into most browsers and continually adding capability helps reduce the barrier to entry. I appreciate that Firefox has chosen to differentiate their dev tools from others by adding a tool like this. Google Chrome dev tools seem to be more focused on performance testing. It wouldn't be a bad thing if one set of dev tools was better for performance and JavaScript debugging and other was better for solving visual design problems.
