Cookie Quick Manager

Overview

Cookie Quick Manager: A complete manager for cookies accumulated during browsing.
It allows you to view, edit, create, delete, backup, restore cookies and search them by domain names. Contextual Identities such as Private Browsing, First-Party Isolation, and SameSite flag are also supported.
In addition, the LocalStorage of the page viewed can be deleted (see below).

Cookie Quick Manager is designed for developers, testers or people
concerned about their privacy on the Internet.

This WebExtension is compatible with Firefox 57 and is inspired by addons like Cookies Manager+ and Advanced Cookie Manager whose development has been discontinued due to the withdrawal of the support for "Legacy" extensions.

November 2018: Cookie Quick Manager is now available on Android!

This addon does not store or leak any personal information.

It requires the following permissions to operate:



About cookie protection

The protection of cookies is limited to the current addon actions, to the deletions that can be made by the sites themselves, or to the deletions made in the browser's "Cookies and Site Data" options.
This means that if you choose the browser option to delete all cookies when it closes, the addon will be unable to restore them (the method used by the browser does not send the necessary signal to notify the addon). However, a similar option is reimplemented in the addon itself in order to keep only the protected cookies when restarting the browser.


What is "Delete Current Site Local Storage" on the popup menu?

This item allows a user to delete LocalStorage keys from the viewed page.

The LocalStorage is a quite new feature of HTML5 that allows developers to create data in your browser using JavaScript. Cookies are just one type of storage among others.
You will also find the term "SessionStorage", a LocalStorage where data is stored temporarily (deleted on browser restart), but the important thing is that LocalStorage is persistent, and cleared only at the discretion of the visited websites.
You may erase all of the LocalStorage store by following the procedure described in the documentation of Firefox, and by selecting "Offline Website Data".

From the point of view of privacy and security:

This kind of persistant data (even after clearing cache), was invented to store small data allowing the operation of online applications, but also offers new and better accurate ways of tracking thanks to the memorization of private or identifying data.


Support & source code

The extension is still in development with the launch of Firefox Quantum; questions, bug reports and feature requests are open on the GitHub repository.
