Rated 4 out of 5 stars

A great looking addon but it has an issue that is a deal breaker for me.

CTRL+SHIFT+T is unable to bring up a closed private tab, where as in a private window this can be done.

Edit: It is a shame there is no way around this. After reading the provided docs I can only hope the FF devs expose the required functionality again some day or provide decent private tabs in FF.

I've adjusted my rating to account for the situation.

This review is for a previous version of the add-on (0.1.7.2.1-signed). 

See https://github.com/Infocatcher/Private_Tab/issues/146
Also see https://bugzilla.mozilla.org/show_bug.cgi?id=956826#c8 (and below).
So, now this is hardcoded inside Firefox "Session Restore" component with special handling only for private windows: https://bugzilla.mozilla.org/show_bug.cgi?id=961380
