Nice. 'Inspect' both page and UI (chrome) elements in one add-on Rated 4 out of 5 stars

This Add-on replaces some others: Element Inspector, Inspector Widget and ....
Because this Add-on is fired (started) from the right-click context menu and not a button, it is easy to 'inspect' elements in a menu or sub-menu of the chrome UI (firefox user interface)... But.. to 'inspect' the context menu it's self, you'll still want to use the icon launched (using Shift+right-click) DOM 'InspectorWidget'. This add-on tries to do it, but it's not as 'good' at it.
Well done.

ps. I'm not saying anything bad about the others. They work and I have and do use them...
