Hi,
I have Firefox set to keep cookies only until the browser is closed (and disabled third-party cookies). Firefox doesn't show any cookies being kept otherwise. However, when I run CCleaner it shows there are still Firefox cookies left behind. Can anyone explain why this might be happening? I am using Firefox 57.0.4 on Windows 7 Pro.
Thanks.

thats fake, forget ccleaner and firefox together. you already were told to leave ccleaner behind:when I run CCleaner it shows there are still Firefox cookies left behind.

where is the problem to trust in such experience?
if you want to keep cookies you have to set exceptions in cookie handling (allow). no entry means deleted.

(use custom setting)
and be sure not to work in a private window.

Re: Why Are Firefox Cookies Left Behind?
I am not going to use CCleaner to clean or compact Firefox - but perhaps planning on using CCleaner to delete Flash cookies (not Firefox cookies).
However, if I do an "Analyse" of Firefox cookies with CCleaner (this does not change anything in Firefox, so no risk), I see extra cookies not shown in Firefox. I would not consider these as "fake" as they are relating to web sites I have visited previously.
I found this link, which seems to explain why this is happening:
https://forum.piriform.com/topic/45043- ... n-firefox/
"I found out it's caused by super cookies in SiteSecurityServiceState.txt, these cookies can't be deleted by Firefox."
So it looks like CCleaner is finding these "super cookies" in SiteSecurityServiceState.txt.
Regardless of CCleaner, is SiteSecurityServiceState.txt anything to be concerned about from a privacy point of view?

That is because they are gone.BrowseMail wrote:Firefox doesn't show any cookies being kept otherwise.
That is because CCleaner fails to clear its cache. CCleaner is crapware.BrowseMail wrote:

CCleaner is known to cause issues with Firefox.

AFAIK, deleting FF cookies deletes the respective Flash cookies.Flash cookies (not Firefox cookies)

Re: Why Are Firefox Cookies Left Behind?
AFAIK, Flash cookies are stored separate to regular cookies by Flash Player, which aren't deleted by Firefox itself. Flash cookies are also accessible across different browsers.
Clear Flash Cookies looks good but I would like to see more options (like a whitelist). BetterPrivacy was great but it no longer supports WebExtensions.

But they are not the same cookies. For example on MacBrowseMail wrote:Flash cookies are also accessible across different browsers.
Firefox flash cookies are here: ~/Library/Preferences/Macromedia/Flash Player/#SharedObjects/
Chrome flash cookies are here: ~/Library/Application Support/Google/Chrome/Default/Pepper Data/Shockwave Flash/WritableRoot/#SharedObjects/

Re: Why Are Firefox Cookies Left Behind?
Right. That's always been the case.Flash cookies are stored separate to regular cookies by Flash Player
AFAIK, deleting FF cookies deletes the respective Flash cookies.
I had been under the impression that it did that, but seems it does not, at least in testing it is not?which aren't deleted by Firefox itself
URL: http://www.republicofcode.com/tutorials ... redobject/
This sets a republicofcode.com "flash cookie" (LSO) [in addition to FF cookies].
Clear FF cookies.
Verify that the republicofcode.com "flash cookie" persists.
(BTW, disable Flash & ... no flash cookies . Where's the milk?)

Re: Why Are Firefox Cookies Left Behind?
As Chrome comes bundled with Flash Player (Flash Player updates are part of Chrome updates), perhaps Chrome stores its Flash cookies in a different place to Flash cookies from other browsers like Firefox.RobertJ wrote:But they are not the same cookies.

Each browser, at least on Mac, stores the flash cookies in different places. In particular Firefox, Chrome, Safari and Opera. Edge does not run on Mac.
