Cookiebro is probably the best cookie manager for Firefox and Chrome, built on the bones of the now-abandoned Vanilla cookie manager extension (which I missed). I highly recommend it.

Cookiebro is easy to use, and relatively intuitive. Keep cookies in whitelists and block cookies in blacklists, and easily purge the rest cookies on-demand or automatically. Import or export lists as a simple text file that is simple to edit. The cookie log view and cookie editor are powerful tools whether managing privacy or just debugging.

Minor issues: While adding and removing list items is easy, one can't edit them in place. For example, if I have "getpocket.com" in my whitelist, and want to change it to "*.getpocket.com", I have to add the latter as a new element, and then remove the former. I also wish the extension would sync settings across browsers, so I didn't have to spend as much time importing and exporting.

For managing and auto-deleting cookies, also try the Cookie AutoDelete (CAD) extension. Choosing between that and Cookiebro is a matter of personal preference. I have found CAD to be a bit buggier, but it has some advantages of its own. While it lacks the Cookie Log and Cookie Editor, these aren't essential for the majority of users.

For those who are cautious about their extension use, the developer (Nodetics) has at least one other extension that is Mozilla Recommended, and I suspect Cookiebro has not yet been recommended largely because the UI is perhaps too minimalist and functional, with less frequent updates.

Interestingly after I forced install, it seem actually work on Firefox Mobile. At least I notice Auto Delete work, which I actually need. Hope it will officially Firefox Mobile Compatible.

I love this extension! Works flawlessly with Waterfox Classic. Lot of options, very useful to preserve login cookies for instance, so you don't have to log again each time. You can see all that stuff that is stored in your browser when you surf and easily get rid of what you don't need, or edit cookies according to your needs, etc. Maybe an option to lock specific cookies could be added, if it's possible, so websites cannot make changes on them (date or data). Thanks anyway to the developer, keep up the good work!

Oke, oke. After your reply I went through cookiebro again and as I said, I like it as the options to allow or block or even edit are great. Anyway, FF is since long not my default browser anymore... I added cookieBRO to Vivaldi and there this add-on cut a figure as the cookie management of vivaldi is still quite spartanic (but there are some recent efforts..) However, will rate ur add-on again on chrome....

This add-on would be perfect. But unfortunately it is not connected to the browser cookie preferences. It works as a stand alone, means the cookie preferences from the add-on won't be updated in the browser preferences... That is not really the idea of an add-on, isn't it?

Not a review and i have nothing to complain about - *i need help.*
Last week or 2, when i start Firefox, check the Cookiebro menu / find that my whitelist and blacklist have disappeared. (Thnk goodness i have them saved.) So far i can see, it is Firefox doing it, not Avast. I don't know whether caused by Firefox setting i changed or yet another troublesome change Firefox made.
I have Firefox set to allow cookies generally.
*Please help.*

I have been using it for 7 months now, after trying many other similar addons, this one is the best by far !!

[I will add new updates below, depending on the circumstances]

[they changed the icon provider from google to duckduckgo which is a safe alternative, so you can ignore much of what I posted below]

Best cookie manager hands down. Absolutely amazing little addon! Whitelist approach with timed removal of unwanted cookies is the best approach I can think of to reduce tracking and maintain a functional browsing! 5 stars! Just found the log and cookie editor which is mind blowing! Can even block or whitelist individual cookies on a single website or globally. There is nothing that I have found that comes even close. Deletes ALL unwanted cookies unlike Cookie AutoDelete, and "Self Destroying Cookies", which left hundreds behind. GREAT JOB!

Be sure to disable favicons if you don't trust sending some of your browsing data to duckduckgo. When fetching the favicon, you send the domain to duckduckgo for icon retrieval. This happens only when opening the cookie editor and log.

Please consider adding an option to delete a tabs cookies, and all the rest on tab close.

This would give it a leg up.

Replaced Cookie AutoDelete, which did not auto-delete all cookies that were not in the whitelist. This extension does. I am so happy. Kudos!

Good addon, but it was really unpleasant surprise that it deletes google, youtube, facebook etc. cookies each 2 hours by default. I spent hours trying to find the reason for my auto-logouts from many sites. I blamed adblocks, anti-tracers, containers...

I would suggest you'd better make default the option "do not delete unwanter cookies periodically".

A very gread cookie Addon for Firefox.
I like especially the clear Option Menu, where you can see all whitlisted sites and other functions. Best of all i have ever seen.
But there is one thing i REALLY REALLY miss:
• I would like to have an option to instantly whitelist a site, with your yellow button, not going in the option menu.
Shame on me: this option is already there, could not see it while testing, because all sites were already whiteliste
• And also interesting: an option to clear all unwanted cookies after some time.
Added: sorry my wrong, this option is integrated, thanks.
But otherwise a great tool for daily work.
So no otherwise anymore: 5 stars: a great addon !!

Very nice, customizable interface which is economical with your time! Nicely designed and it works too!

Great extension! For me, this replaced the frustrating Cookie Autodelete. Superior features include: fine grained control, simple file format for saving/editing/restoring white list, built-in cookie editor, and much more.
