Undo close tab doesn't work as it works in 'Default New Private Window' of Firefox. I think each 'Private Tab' is a 'New Private Window' in itself. Anyway the undo tab history can be mantain until atleast one 'Private Tab' is open like sharing memory, info between different tabs open with 'Private Tab'?This review is for a previous version of the add-on (0.1.5.1-signed).
