How to reopen closed incognito tab in Chrome?
Solution 1:
I don't think you can, or even should be able to restore closed tabs in incognito.
Think about it for a second. By switching to incognito mode, you're asking your browser to not follow you around and not keep local data, and a second later you're asking for a closed tab? Kinda beats the purpose, no?
If you must have this functionality (again, beats the purpose of incognito imho), you can use a session manager (like Session Buddy) and mark it OK to run in incognito.
Solution 2:
As Sexy undo close tab has been removed from Chrome web store, you can try
Simple Undo Close, which is fork of the Sexy Undo Close Tab extension.
Also take a look at Simple Undo Recents.
