Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.

I want to know the cookies a web page uses and whether they use cookies placed on the computer by other websites.

Is there a way of knowing this or even an addon for it?

People, answer the question!!

There are extensions for that. But one universal way to do this is by opening the developer tools, either by hitting the F12 key like another commenter briefly mentioned, or thorough the application menu.

Then once the developer tools panel pops up, go to the Storage tab, select Cookies, and there you are. You'll see a list of cookies grouped by the domain names they come from.

This isn’t precisely what you’re asking, but I like using NoScript. It denies all JavaScript by default and allows you to whitelist by domain. It’s interesting to see how some sites load JS from dozens of different domains (Imgur, Politico…). One can assume that each of those sites is trying to use cookies and/or site data for tracking.

whether they use cookies placed on the computer by other websites.

It should not happen on Firefox because of First Party Isolation. Basically it puts all the cookies created by a domain inside a virtual jar and makes the jar inaccessible by other domains.
