This no longer works in Firefox 86.0 64-bit on Linux as of at least this week (1st week of March, 2021). Many cookies are left after clicking "Delete Current Context Cookies." The only way to clear the cookies is to restart Firefox.

I dont know for what such high marks, but simply I couldn't add cookie at my site. I can change cookies but I have to add. So "remove"

I tried to protect some cookies. Then, in Firefox 78.0b7, when clicking " Cleaning Data", all cookies are deleted even so-said protected.

Doesn't allow you to create cookies.

Can I toggle cookies on and off on this app? It didn't state whether that functionality was possible specifically in the spec.

I tried to use it for only one function - to block the change of a certain cookie. Seems it allows you to do this, "Prevent sites from clearing protected cookies, even if they are expired" is enabled in the settings, but cookie still changes.

Doesn't work, clicking on icon just shows a popup with a list of cookies but clicking on anything does nothing, absolutely useless.

Extremly useless. Bad user interface. Filter for domains is not prefilled with the one of the current tab. This is a really bad extension.

EDIT: The problem in your link is a different one. The addon works. I can view and delete cookies but when I open the extention I want to see all the cookies of the current domain. I don't want to filter manually.

Ужасный интерфейс. Программа просто удалила все мои куки и не дала с ними ничего сделать. Бэкап? Пфф, бэкап для слабых!
