|Feature open issues and risks=* What happens to the Highlighter Toolbar breadcrumbs when you have a very deeply nested tree? Is there truncation at one part of the tree or other? (my initial thought is to truncate at the tree's routeroot)
|Feature overview=The Highlighter is a web designer-oriented feature that was initially planned
for Firefox 4 (as the Inspector) but was not ready in time to ship. The time in between has allowed us to rethink the tool.
