Much more detail that the built-in cookie UI. Aware of container tabs, which is a big plus.

I using this plugin, but if have no alternative after ff57.
Feature request: add keyword search. For example, i need to delete all cookies from aliexpress.com work. Now i need to select several domains to do it. Just entering word "ali" can select whole cookies from all domains at once.
Update: (How to write new report?) Next thing: Expired cookies (colored in red) - why its are not deleted immediately, like the rest of the usual cookies? Why such difficulties with editing, it's a waste of time, which negates the entire speed of working with cookies. I was really annoed until I finally read popup message under thats cookies.

I don't understand how to change a value within a cookie.

I would give a 3 star but this is a good enough alternative to other cookies manager now that firefox killed all others. Now the only thing will be to improve the UI and this will be a 4-5 star.

Not better than Cookies Manager+. Thanks FF Quantum... UI is not good yes, but it works. 4 stars for another alternative.

Sort of functional, but the user interface is pretty bad.

You can search for cookies, but only if you already know exactly which cookie you're looking for. E.g. if you know that cookies have a "host" field, you can enter an exact name there and click "search". It only finds exact matches (no substring search) and there is no autocompletion. The UI form is spaced out all over the window, so you might not even see the buttons at the bottom at first glance. As far as I can tell, you can't really edit existing cookies. There's a "new cookie" form (which completely replaces the view/search form, you can't have both open at the same time) and its fields always start out empty, even if you had an existing cookie selected before. Even if you've managed to create your own cookie by filling all fields and clicking the "save" button, there is no apparent way back to the overview screen. The "new cookie" form just stays open and sits there. Fortunately the "cancel" button doesn't actually cancel your new cookie but takes you back (?).

3 stars because the add-on technically works (I think?), but the UI is borderline unusable.

No privacy policy. Your add ons have access to sensitive cookies and data. Yet, No disclosure as to how you intend to use such sensitive data freely available to you.

EDIT: Updated my rating. Still, I would feel better, if the privacy policy link is updated in the add on descriptions or in the official Mozilla add ons privacy policy section.

I couldn't use this anymore, despite I'm using the Firefox on android.
It kind of worked from the beginning, after awhile, it required me to choose something called "Cookie Jar" from the list, but the list was completely empty and I couldn't Save the edited cookie.

What happened all of the sudden? The choosing "Cookie Jar" option never popped up before and why now? I tried uninstalling it multiple times and that option still popped up.

Thanks for beginning a cookie manager for Fx 57+. I know it's brand new & takes a lot of work. Just trying to give some useful suggestions.

1) Re: Taurean75's comment: https://addons.mozilla.org/en-US/firefox/addon/a-cookie-manager/reviews/896808/ - -
yes, I think they meant as in the link you posted: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/user_interface/Popups.
That's the way many addons provide menus, where options may require frequent changing.

2) If I understand, why have any addon open in a NEW TAB, instead of using a toolbar icon? Not a requirement for Fx 57 / webextensions? Or just the fastest way to get Cookie Manager up & running?

Most Fx 57 ready addons I use allow adding icons with drop menus to toolbar. Few require using about:addons to *change* (most) options - especially for cookies.

3) Suggestion: post a few more screenshots on MAO w/ some explanations. Probably entice more users to try it. I see Cookie Monster's dev has pulled it from AMO. Lots of users will be looking for replacement.

Keep up the good work. For ideas, I'd look at features in the more popular cookie managers - that aren't updating to webextensions.

If you want feedback of what's most important to users to implement 1st, maybe setup a support page on http://forums.mozillazine.org, as other addon devs did. One post could be a poll for wish list.

I could tell you some cookie features I've used most - for years, & read others say were important to them, but it'd make this review long(er). Maybe you don't need ideas for now. :) But, feel free to PM me.

Edited review 08/13/2017: correct typos

A little inconvenient but it works!

A pop-up UI would be nice instead of enabling / disabling it.

RE: Either one would do.

EDIT: Thanks for taking my suggestion!

It's the only add-on I find to show session cookies in private window but still it can't delete cookies in TorBrowser [7.0.1 (based on Mozilla Firefox 52.2.0) ], throwing this error:
`Cannot modify 1 private cookies because the sites are not reachable. Try to temporarily disable Tracking Protection at Settings > Privacy.`
Tracking Protection is off (It's so by default in TorBrowser). I disabled NoScript but didn't help. Any idea?


UPDATE:
And where is 1.3? :)

UPDATE:
I got 1.3 from git repo and It worked! thanks following this!

Powerful tool

What circle in the address bar?

Final edit, sorry for all the edits.
Dev responded to my review and addressed issues mentioned. This Ext works wonders. Super useful IMO! Thanks. Oh.. "Options" still doesnt do anything when touched. Not sure if norm.
