How do I find out which cookies are used?

Post by Kracov »

I have cookies disabled by default, and a whitelist. I often come across problems logging into certain websites (which I can usually remedy), but this isn't the issue. This time there are several facebook instant games that won't run while cookies are disabled. These are small games you run while in messenger with a friend. One example is "apps-141184676316522.apps.fbsbx.com" and I already tried adding fbsbx.com and appspot to the whitelist. Doesn't work. Tried finding the cookies while in a new profile, it just shows the fbsbx one. Tried several cookie manager addons, they don't show a list of new cookies.

In Tools/Options/Privacy & Security - under History make sure you accept cookies for the main site, not necessarily third party cookies.
Change the setting "Keep until:" to "they expire" in your new profile.
These cookies should not be erased by closing Firefox.
See what has changed, maybe the domain url has extra characters or is different somehow.
There's also the possibility the cookies are on a single use and do not save.
You might want to address this to Facebook.
Doesn't matter what you say, it's wrong for a toaster to walk around the house and talk to you

whitelisting no good, 3rd-party cookies are recommend and in most cases needed.
try "cookie autodelete" (webextension) to manage deleting cookies automatically.
Tried several cookie manager addons, they don't show a list of new cookies.
there never was an extension to show new cookies - and currently there is no webextension for that. you have to check out yourself but as stated it makes no sense to do as you did before.
but - any decent cookie manager can show expiration date of a cookie that my be a hint for its creation date.

So there's no addon that better controls whitelisting and third party cookies?

Did you try to use the Storage Inspector to see what cookies get created when you have (temporarily) allowed all cookies including third-party cookies?

You can set network.cookie.thirdparty.sessionOnly to true on the about:config page to make third-party cookies behave as session cookies that expire when Firefox is closed.

There's some useful about:config settings you can employ to achieve your goal of maintaining privacy on this site: https://feeding.cloud.geek.nz/posts/twe ... n-firefox/
