Excellent - until before version 42 Rated 4 out of 5 stars

Did see the developer's reply about FF v 42 not playing nice with this extension.

Do hope that the developer himself / herself or some one quickly figures out the issue and fixes it.

Why does Mozilla break several good extensions when releasing a new version - when the new FF version itself does nothing new in terms of USER functionality in the specific area (cookie exception handling) that it breaks??

This review is for a previous version of the add-on (1.0.2).  This user has other reviews of this add-on.
