I really want to like this add-on because the concept is great and the interface is good; however, there is a huge flaw. I will delete a cookie from a given website like Youtube using this Cookie Quick Manager but when I go into my Preferences>Privacy Security>Manage Data and open the folder, THE COOKIES ARE STILL THERE :(

I generally love Firefox but I am furious how they changed the cookies. They used to be so easy to delete but now you have to jump through a lot of excessive hoops to delete your cookies. This is a nefarious attempt to favor tracking your behavior and is total garbage. I was hoping this add-on would liberate me from the cookie fiasco created by Firefox but I don't think it works for the aforementioned reason.

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.

very bad UX.

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.

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!
