Why it should have permission to modify privacy settings now?! What's required by specific features could be given by telling user what should be, and how to be edited, or at least provide an option to let extension asking users who needs these features to allow these permission.

--------
Edit 1: Thanks for your patiently reply. Despite that the permissions are required, this extension's context support helped me in time to perfectly experience FF Context feature.

As for granting permission, there's a extension called "SiteDelta Highlight" on AMO you could refer to. Click into its settings page, which displays prompt "Advanced features (that require additional permissions) are disabled." with a button "Enable advanced features...".
Then click on that button, Firefox will prompt it requires additional permissions. So I think it should be able to grant several parts of permissions separately.

And a few advice:

1. Add context to directly "move to container" rather than only "copy to"

2. Ability to select multiple domain / multiple cookies at the same time

3. Every button in the bottom has hang-over tool-tips except the first one from left (and the forth, well it's easy to guess it is for donating). So... the first button with a trash bin icon is so disturbing I don't know what scope it applies to, neither know if it will ask me to sure before doing something.

4. Right-click context menu is not fully visible when click on item close to window border.

5. Why I couldn't copy expired cookies to other container? if it's exist when I access its website it would seem to be refreshed, so it maybe useful, why can't move it?

Great extension for both viewing ad deleting cookies. However, the latest update put in a "feature" Idon't like - the confirmation for deleting all cookies. There should be a way to turn it off once someone is used to the severe effects of this feature. I open individual sites in new private tabs in Firefox and so when finished, I need to remove all the cookies. I do this continually so I dislike having to confirm each time. There should be a way to turn it off.
Another feature I like with the latest revision is the ability to auto-refresh. However, that feature only stays on until the next time I open Frefox. It should be persistent.
Other than these two issues, this is a 5 star addon.

Works fine, but it is not particularly easy to find the cookies for the current page and quickly edit them

kann als einzige Export/Import, backup restore

chrome://browser/content/preferences/cookies.xul is dead.
Long Live Cookie Quick Manager!

I like this. The only thing that strikes me as odd is the way it treats domains such that, for example, .addons.mozilla.org and addons.mozilla.org appear separately. I prefer the way cookies.xul did it.

Finally an intuitive and powerful cookie manager! The latest update is great, as it supports Multi-Account Containers with optional filters by container. Excellent addon!

The best cookie manager atm

Works well – thanks, ysard!

This is the best cookie manager for developers that I've found so far for recent versions of Firefox. I previously used Cookies Manager+, before Firefox Quantum broke it. Cookie Quick Manager isn't a full replacement for Cookies Manager+ yet, but it's decent, and I sense that it will continue to improve.

One suggestion for the author: I wish that the "Delete all the cookies" action were harder to do accidentally. Perhaps a confirmation dialog or moving it to a menu would help. There are three trash can icons without labels and the "delete all" button has very wide reaching side effects.

The manager window doesn't display any cookies. Searching doesn't appear to work. The "refresh" button doesn't populate a list of domains, or have any other obvious effect. In short, the addon doesn't seem to work.

ETA: Developer responded on the GitHub issues page and diagnosed the problem for me: the extension doesn't work with First-Party Isolation. I will re-test and update the review as soon as I can. Bumping to 5 stars in the meantime for the fast response and the excellent diagnosis.

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.

Works well for me. Thanks. :)

Great addon with a lot of functionality to manage all cookies. It also works very well with Containers.

Have exporting to clipboard function, but have no importing from clipboard function

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

One of the few Cookie manager that works with FF57+ and has a user friendly interface.
