Not working if 1 tab open Rated 4 out of 5 stars

I love Close 'n forget, but I do have one issue to report. If I only have a single tab open, Close 'n forget doesn't blank it, as it would do if I used the close button.

Admittedly, I haven't checked if cookies are erased, but if the tab isn't blanked...

This review is for a previous version of the add-on (0.7).
