Definitely 1 star, it does not work at all as advertised with following browsers:
1. Official Firefox with [FPI enabled] & [Always use Private Browsing mode on]
2. Tor Browser

I just want an add-on which deletes cookies after several seconds after I close tab EXCEPT some domains I whitelist. Now this addon, Cookie AutoDelete, blindly ignore my whitelist settins and always show Cookies were deleted popup. I am 100% certain my whitelist settings are correct and I already took 2 hours to search through Github issues.

Developer of this add-on need to test with Tor Browser or Firefox+FPI in the first place.
