Firefox now has it's own inspect context menu entry but his add-on allows you to easily inspect context menu entries themselves!
Unfortunately e.g. the sub-menu for the spell checker dictionaries cannot be inspected.
The inspect entry is at the top of the context menu. I'd rather have it together with the inspect entry of Firefox. This add-on's entry cannot be moved with Menu Editor. I would appreciate this possibility.
