The setting "Auto-delete indexedDB and localStorage of websites at browser startup" causes blank pages for several sites including imgur, ticktick.com, and qfc.com. Clearing cookies now throws an error message as well.

It works, but I really don't like cookie logging. I very much don't like the way that cookie logging is enabled by default either and how it resets to being enabled whenever I run CCleaner and Bleachbit on my system. Other than that though, this extension does a great job of deleting unwanted cookies without restarting Firefox, and it also does great at protecting cookies that I don't want to lose. As I said though, logging should be turned off by default. In fact, I don't see any excuse for there to be logging of cookies in any event. I see it as a possible privacy exploit. Webextension data SHOULD be cleaned. Perhaps the extensions settings should be stored some other way if possible. I have no intention of ending my use of such tools as CCleaner and Bleachbit.

*** EDIT ***
All of a sudden for some bizarre reason the Whitelist is empty when I run Firefox, every session I can add sites to the Whitelist but on relaunching Firefox it reverts the Whitelist back to empty :(

Finally! A decent cookie manager that actually works for the stupidly restrictive, uncustomisable and broken mess that is Firefox Quantum 60+ ... or as I call it, Firefox Can't 'um do anything useful with it.

Very unintuitive. What is the default action for cookies with this addon? What happens to cookies that are neither whitelisted nor blacklisted? I have this add on installed and I honestly still don't know how my browser treats a cookie from a brand new site. What is the point of a cookie log that doesn't tell you how the cookies were handled? How should content blocking in Firefox settings be configured? Why write an addon with zero documentation? Hey, geeks can use it so who cares about normal people?

Ugh I miss the old Cookie Monster addon, so intuitive and easy.

Cool addon, but cookie search is a bit strange. It would be more logical to filter search results according to searched expression. If this functionality is added in the future, I will increase my rating :)

I hope to support the traditional Chinese interface.

Cookiebro is a functional cookie manager but UI needs some work and UX improvements.
For example: Current search implementation in cookies editor is of little use when there are more than a few dozen sites with cookies and I have 477 sites. Filtering and displaying only matching entries would be a much better approach. Just like the old Firefox cookies manager or about:config page.
I'd like to also suggest merging all different add-on pages in a single page with tabbed UI.

I was hoping this would automatically work with the whitelist I set up in Firefox Options before my prior cookie button fell victim to Quantum, rather than having to rebuild a new whitelist. I would like to use Firefox Options to block all cookies, then use a simple add-on button to whitelist particular sites. (Going Firefox Options to add exception is a big huge pain when you are in the middle of something.)
