it does exactly what I expect

Cookie Quick Manager is a very complete cookie manager with an ergonomic user interface. Unlike other addOns, it allows you to edit, backup, restore cookies, search them by domain names and so on. This addOn is perfect for who has a clue of what he/she is doing and is not only looking for a "delete all cookies" button.
The developer is also attentive to his users.
Great work, carry on!

Great add-on, everything works as advertised, developer is ready to help everyone - even those who never read description text. Great work, thanks for sharing.

a worthy successor to the good old "Selective Cookie Delete". Especially the option to lock/unlock cookies is worth gold. What I would like to see is a quick option "Delete ALL cookies" (except the locked ones of course) right in the main menu, that would be really great. Saves the long-winded way via open Manager/scroll down/click trashcan-icon. Should be hopefully feasible - at least optionally, or via a keyboard shortcut? However, "thank you" for this useful add-on.

Excellent plugin, simple and clear. As a developer I use it regularly, never failed me yet.

Feature request:
Add a cookie manually.

excellent

Очень удобно. В отдельных вкладках показывает куки только для хоста этих вкладок.

nice !! cool !!

very good, traduit parfaitement en tout lieu, très utile, merci

I Like It...

So far so good. I needed an extension to edit cookie values since Firefox Quantum removed this functionality from the F12 developer toolbar, and since Google recently changed its privacy opt out mechanisms (see Personal info & privacy > Tools you can use now) to expire opt-out cookies after random short durations (30 minutes or less in some cases) and randomly 'forget' certain opt out settings. This extension did the trick. I am not happy with FF Quantum's all-or-nothing privacy permissions but that's not the fault of this developer -- I appreciate the transparency of this developer in explaining why such broad permissions are needed by the extension.

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!

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.
