Рейтинг 5 из 5 звёзд

@deeny for his post/rating : the developer has clearly mentioned :
"Attention: CS Lite Mod (version 1.4.9.1) doesn't work with Firefox 42 or later. I'm considering measures because this add-on needs a major change.", so rating badly when information/explanation is provided seems to me inadequate.

Indeed, a new version is required. My hope is that the author will carry on this excellent work -- the best in its category IMHO -- so that it may continue to be the excellent companion to cookies' management.

Hence, I stick on/with 5 stars because the unavailability is only the fact of an update. The add-on's architecture is valid and well thought.
