· U+202E (RTL character) messes up the source code
· Firebug doesn't see number properties anymore
· Closure Inspector: some variables are treated as DOM properties
· Closure Inspector: named function expression scopes are duplicated
· layout panel raises "target is null" error (firebug.js:2439) html layout 1.12a1
· Some elements shown as non-expandable in the DOM panel
· FBTest net/4382 (JSON Sorting) fails
· the DOMTokenList testing

Closure Inspector:
· Close Inspector feature is nicely integrated within Firebug UI and can be used to inspect javascript closures. Let’s see a few examples demonstrating how to use it.
