Fantastic. Does what it says on the tin in a no-nonsense, usable way. Just what I needed.

The interface is a bit "shocking" the first time one sees it, like some raw data spat out of a debugger, but it is, actually, very thorough and unobtrusive, showing all the information of a cookie or the cookies of a domain. It recognises user containers (cookie jars) and, the best part for me, it is fully compatible with Waterfox (the lifesaver after the series of Mozilla's Firefox's add-ons hell, which started with the obligatory certification, then the dropping of XUL, instead of just incorporating WebExtensions, and the last one, the absolute dumbness of letting all add-ons' certificates expire on 2019/May/04).

Only addon that helps me with Cookies Import/Export.

This is a good tool for both development and training.

可以导出两种格式的cookie，还能选择指定页面的cookie，功能比起大多数其他扩展要完整和实用的多。界面什么的不重要，实用就行

Everything fine, but the design (I mean it's as if there was no html5 standard even in planning).

Terrific add-on (for a short time, when I opened it and clicked on "Search" I got the message "Failed to fetch cookies from cookie store firefox-default: First-Party Isolation is enabled, but the required 'firstPartyDomain' attribute was not set", which was fixed by the developer with a new version 1.5). Thanks for your excellent work!

Please support the `SameSite` cookie attribute, along with httpOnly and secure

nice

Nice, you should insert an AUTODELETE option to delete any non-whitelist cookies after closing/restarting the browser.

Initially, I stumbled around trying to figure out how to work the query tool. After understanding how to use it, I think Cookie Manager is the best cookie manager around. Sure, it looks more like a character-based user interface than some fancy-shmancy web-based interface, but I'm ok with that; in fact, its growing on me the more I use it because that interface offers a LOT of flexibility (i.e., power).
