Cumpre o que promete, muito útil em sua função.
Parabéns aos desenvolvedores.

I would like to have current website cookie settings displayed without having to go to a new window.

What an awfull pice of crap this extension is.. Seriously, it looks like a student school version extension developped with classmates.. Uninstalled two minutes after I installed it.

It works perfect, it solves the fact of having to send cookies from android to pc.

In comparison to Cookie Quick Manager, this is just a worse version.

Function over Form.

It's not pretty, but the minimal interface is intuitive enough if you have preliminary understanding of how cookies are constructed. It gives a nice overview of all the cookies and its values. It's perfectly fine if you've used excel or deal with data on a regular bases.

Developer: If you want to simplify things. Make beginner and advanced modes. By default hide all search filters except 'Domain' and use fuzzy search since that's what most people are going for anyways. Ctrl+Shift Selection if possible and Inline editing couldn't hurt either.

So ugly I want to stab out my eyes. :-(

This add-on may have sophisticated functions, only the appearence is non-self-explaining. What shall I do to achieve my needs? I am not an IT-specialist.

I am giving this a high rating because it's the best cookie manager in Firefox I've seen that supports Quantum. That said it's far from perfect, just from using it for a couple of minutes:

1) The URL Search does not seem to work, and almost got me to immediately uninstall (fortunately the Domain search works well)
2) The UI is not pretty, but functional (also why does it ask for confirmation to delete a cookie? It's not a big deal if you accidentally delete a cookie anyway)

not convenient, doesn't work for separate tab with site. Only accesible in settings tab

Editing cookies doesn't work (I clicked Add / Edit cookie, Copy last selected, wrote my value and hit save, and nothing happened. Cookie still bears the old value), UI is crappy and user unfriendly. Definitely wouldn't recommend for anyone looking for replacement of legacy but well working https://addons.mozilla.org/en-US/firefox/addon/cookies-manager-plus/

EDIT: To adress author's comment - I mean the value of the actual cookie. It doesn't update in interface neither touches the cookie at all. It still has the value that it had before I tried to edit it (tested with my own website).
I suggest you to fix the bugs, make standart addon interface - a window rather than HTML page (So I don't have to type the adress myself, but just click the button on the page where I want my cookies displayed). Then I will gladly change my rating and will happily use this addon. Until then, disabled.

Still don't show any cookies...

This extension will NOT delete cookies with V57.0.
To test this extension, I started by trying to delete expired cookies.
You can select them in the UI and click the "remove selected" button at the bottom and they will be greyed out in the list but that is it. If you refresh the list they are not greyed out any more.
Since there is a "restore selected" button I thought maybe you had to close the tab to complete the delete but that didn't work either. I even set the FF Tracking Protection to Never.
What am I missing????

Looks like V1.4 fixes this issue

Please add support for resizing and sorting columns.

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.
