Nice extensions, but when it's firstly installed it should warn the user about the options that are enabled and shouldn't delete the cookies straight away. Also you should include a feature that would let to block some LSOs from being deleted because some are used as normal cookies, like a safelist or whitelist.This review is for a previous version of the add-on (1.25).
you obviously did not install the latest version which is 1.24! Mostlikely you did not install from here but from another site linking an older version (which?).
I am sure about this because 1.24 never deletes cookies without asking the user. For sure the user can allow to delete them automatically but he once has to confirm that feature first.
Also version 1.24 in deed DOES provide a whitelist. In BetterPrivacy's options you can protect/whitelist single cookies or even whole cookie folders.
But don't panic. I am pretty sure that your old version will be updated very soon by Firefox's built in update feature. However, if you cannot wait, get the current version from my homepage.
