Hi,

Is there an addon that clears all cookies when a certain tab is closed?
Only cookies created or written to on that tab. Limiting to third party
cookies would be wonderful.

Would opening that site in a private tab do it?

I know that I can erase all cookies on closure of FF. I do not want
this, normally I accept cookies of well behaved sites, and I want my
preferences from session to session to keep.

Why?

Because the regulation on cookies in my country (Spain) has changed, and
now several sites say that if you do not accept all cookies you have to
pay. Thus, I can accept them all and erase them on exit, and their
purpose is nullified.

An alternative would be a browser mode that keeps cookies from a tab
isolated from any other tab, so that what they find out about me they
can not share to other sites or advertisers.

In extreme cases, I do this using separate FF profiles. But I would need
too many.

Cheers, Carlos.

Can be done with the definition of exceptions. That's the way I do it.
Usually all cookies deleted except the defined ones which are stored.

"Ausnahmen verwalten" in the German version. "Manage exceptions"(?) in

Sounds like you want Incognito Mode. Alt+F and select New Private
Window.

Too complicated. There will be hundreds of exceptions, maybe thousands.

Seems to work, yes. I closed the tab (the only private one, so it closed
the window again), opened another private window, went to the site, and
it asked me to allow tabs.

Use separate profiles for different tasks.

Firefox does this by default since April last year.

Why don't you just click on the padlock icon in the URL panel of the Tab
you don't want cookies retained, and delete cookies as you go.

That's good to hear. Do you know whether Chrome does the same?

That's cookie *isolation* by domain. Nothing to do with cookie
*retention* by domain (as others have already mentioned by using cookie
exceptions which are site preferences).

Doesn't sound like you want cookie management on a per tab basis. What
you describe is cookie management per domain. You can purge locally
cached data in Firefox when it exits, but you can add exceptions to
cookie flusing.

about:preferences#privacy
Cookies and Site Data -> Manage exceptions

Note that this is a site preference. If you clear Site Preferences on
exit from FF then you lose site preferences, like cookie exceptions.

about:preferences#privacy
History -> Clear history when Firefox closes (enabled) -> Settings
Deselect flushing Site Settings on exit to keep cookie exceptions.

Alas, site preferences saved across web browser sessions have been found
to cause vulnerability, like with HSTS. That was corrected a while ago.
I flush everything on exit. If you want to keep cookie exceptions, do
not flush site preferences on exit.

Cookie exceptions was never meant to be a huge import of an existing
list containing thousands of entries. You build the exceptions as you
go. If you don't visit a site, you don't need cookie exceptions,
because you'll never their cookies. If you visit a site, you can then
decide to add a cookie exception for them.

Private (incognito) mode will /not/ save any cookies when the private
tab or window closes. That's the opposite of what you asked for. You
would have to always use private mode (it is an option) for all but the
sites where you need to not use private mode to keep those cookies.

about:preferences#privacy
History -> Always use private browsing mode

Which do you do most?
- Open most sites in normal mode?
- Open most sites in private mode?

https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history
https://support.mozilla.org/en-US/kb/common-myths-about-private-browsing

If you configure Firefox to start and always use private mode, you will
need to keep using Ctrl+T (new tab) or Ctrl+W (new window) to open
non-private tabs/windows when visiting sites where you *do* want to save
cookies on exit. Considering how often you want to keep cookies at some
domains, and flush the rest, using cookie exceptions seems an easier
method than having to keep using Ctrl+T and Ctrl+W, and do so the next
time you want to revisit the same sites while not in private mode.

+1; a browser is a growing organism.

Commercial sites can use hundreds of cookies. At least too many to go
one by one making an exception. I would like one setting per tab.

What I am doing now is that when I open a newsy site that says: or you
accept all my cookies or else, pay, I reopen that site on a private
window and accept all cookies. Specially on the phone. The nuisance is
that the question may be asked the next time.

I am not sure that when I open a site on the computer, all third party
cookies are isolated, as firefox claims. The sites demand acceptance of
third party tracking cookies.

https://paste.opensuse.org/pastes/675d4b5e6f13

https://paste.opensuse.org/pastes/0bfcb150d782

And this is not the most intrusive site, I don't see the cookies
mentioning sharing with other sites. Notice that now, customizing the
cookies doesn't work. You can try, but then they reject the choices and
refuse entry to the site. I particularly dislike the cookies identifying
the user and the machine or the precise location.

Ah, in some of these sites I can disable scripts. I mean, I do and they
continue working (others fail to work). But first I have to accept open
the site, then mark disable scripts on ublock.

What do you when clicking a link in email to open it in a private
window? Because TB only says "open in browser".

Currently I copy link to clipboard, then paste in an already opened
private window.

Currently, most in normal mode. Those that insist on accepting all
cookies or pay, I reopen in private window.

But my mode of operation would be a list of web pages in which to reject
cookies. Not a list of exceptions to accept cookies.

Besides, can't be, the pesky sites do not work unless all cookies are
accepted. They would have to be accepted silently everytime, no popup,
then deleted silently when the tab is closed. Possibly when all tabs of
that site are closed, instead.

And all of them are at one domain. The exception would be by the
domain, not for each different cookie generated for the same domain.
Have you yet looked at the cookie exception list? You add entries by
"address of website", not by name of cookie.

And an exception for that site would work for all cookies from that
site. Private mode or optioning FF to purge cookies on exit will get
rid of all the cookies on exit, unless you define an exception. Without
an exception, yep, whether for private mode or purge on exit, you'll get
prompted the next time you revisit the site.

Getting rid of the cookie banners is a cosmetic filter. You can
subscribe to blocklists on cookie banners in an adblocker. Previously
there was another add-on that had its own blocklist to do the same
cosmetic filtering.

Even before the isolation was added, you could block 3rd party cookies.
That does NOT block writing cookie .txt files for use on another domain
should you go visit there. Any site can write anything in the cookie
file, even for another domain, but a site can only read cookies for its
domain. Blocking 3rd party cookies is not allowing cookies written for
a different domain (by a different site) to be read by the site you are
visiting. If a site says you must permit *writing* 3rd-party cookies,
those aren't usable unless and until you visit the other site(s). Even
a site that writes a 3rd-party cookie can't read it.

> https://paste.opensuse.org/pastes/675d4b5e6f13

With an adblocker (uBlock Origin), and the blocklists to which I have it
subscribed, I don't see those cookie banners. Firefox desktop and
mobile both allow installing add-ons, so I have uBO on both.

With uBO, I don't need to disable Javascript to block the cookie
banners. The blocklists take care of those.

I don't use Tbird, but "open in browser" sounds like Tbird would not be
loading in its own tab, but passing the URL string to a web browser. If
you really want Firefox to always open in private mode, and you
configure it that way, then Firefox will open in private mode no matter
where you clicked on a URL string.

> Currently, most in normal mode. Those that insist on accepting all

So, it seems you do not want Firefox to always open in private mode.
You mostly want it in normal mode, and only sometimes in private mode.
The objective is to circumnaviate the cookie banners. One way is to add
an cookie exception that a site (but also not purge Site Preferences on
exit from Firefox since those are where exceptions are stored) which
would keep your choices in a cookie on a revisit, so no prompting. Or
use an adblocker that subscribes to blocklists on cookie banners.

> But my mode of operation would be a list of web pages in which to reject

So, you want to reject all cookies except at a few sites. Well, purging
cookies on exit from FF but having a few exceptions does that. All
non-excepted cookies get purged, but the excepted cookies remain.

Hmm, so now you want to allow cookies (notice plural, so saying "all" is
superfluous) at sites, get rid of them on exit from FF, but not be
bothered with the prompting to accept all cookies on revisit to some
sites. Sounds like the purpose of an adblocker that subscribes to
cookie banner blocklists.

If you want to ensure you keep the cookie for the site that demands you
keep them, use an exception, and only there is the exception needed.
Then when you revisit, you still have their old cookie for reuse. Are
you saying you save their cookie, don't purge it, and on the next
revisit they nuisance you again with saving their cookie?

That's a problem. I don't want those 3rd-party cookies read by their web
site even if I happen to open it later.

The objetive is to open sites that demand accept all cookies or pay a
subscription, accepting all cookies till I close the tab, then delete
them automatically, and impede 3rd party cookies from been accessed even
if I open their website. Keep all cookies readable only from inside the
current tab.

Or impede their tracking purposes from working.

The banner is not really a problem. Seeing it confirms that they were
deleted the previous time.

In private mode no cookie is kept at all, I understand.

I don't know, I have a headache.

You really do not understand how these exceptions work. You not even
tried to understand.

So purge all cookies on exit, and add an exception for the one, or few,
sites where you do want to keep their cookies for reuse on revisit.
Cookies last until the web session is over.

A site can write cookies for its domain, and for other domains, but only
those other domains can read those cookies. For those few sites, you
can use Ctrl+Shift+P to open a private window, or configure Firefox to
always use private mode (but you mostly use normal windows for most
sites). A private window won't inherit existing cookies from the
current web session. Another window cannot get at the cookies created
in a private window.

I don't know of an option in Firefox that adds an exception to sites to
make just them open in a private window. However, Total Cookie
Protection in Firefox isolates cookies to a domain.

https://support.mozilla.org/en-US/kb/introducing-total-cookie-protection-standard-mode
https://blog.mozilla.org/en/products/firefox/firefox-rolls-out-total-cookie-protection-by-default-to-all-users-worldwide/

Doesn't matter if a site generates .txt cookie files for itself, or
writes them for other sites. When you open a new tab to the other site,
the cookies written by a prior domain are not usable in the new tab.
TCP isolates the cookies a site creates to only that site. The site can
still write a cookie for elsewhere, but the other site won't find them.

To be safe, I would change from clicking on URLs to open another site
within the same tab to using middle-click to open the other/next site in
its own tab/window. I think TCP works on domain boundaries for cookies
which should mean any cookies a site creates can only be used at that
site, and are not shared with other domains. A site writes a 3rd-party
cookie, but only that site can access that cookie, but that site can't
even read the 3rd-party cookie it created. With TCP, all cookies
created by a site are isolated from use elsewhere. See the 2nd article
above on how cookies are put into an isolated cookie jar per domain.

If you disable TCP then you no longer have the isolated-by-domain cookie
jars.

about:preferences#privacy

Standard and Strict include TCP (Total Cookie Protection). At first, it
was the Strict config, but eventually Mozilla added TCP to Standard
mode. You would have to use the Custom TCP config to deselect cookies.
I currently use the Standard mode. In Strict mode, I've hit some sites
that don't function properly, but that could due to more stern
restrictions in the Strict mode. When I select Custom mode, cookies are
enabled, by default, with "Cross-site tracking cookies, and isolate
other cross-site cookies" selected by default.

And subscribed to which blocklists? Go into uBO's config under the
Filter Lists tab. The EasyPrivacy blocklist includes paths at domains
that would try to create or use cookies. There are Adguard and EasyList
cookie blockists (to get rid of the nuisancesome prompts). I have uBO
subscribed to all blocklists, except uBlock badware risks, and any hosts
files (currently only Peter Lowe's hosts file is listed, but you could
add URLs to others under Custom). That's how I added the PUP Domains
Blocklist. When blocklists have duplicates, those are removed from the
memory copy of the table which is where the adblocker looks for matches
since RAM is a hell of lot faster than opening and parsing through files
or databases.

When I visited your first URL to https://www.eldiario.es/, I got no
cookie banner. There is a "publicidad" placeholder for whatever was
that content that uBO blocked, but I don't if that is what gets used to
display their cookie banner. That also means that I don't have the
option to accept or deny "all their cookies". Since I haven't inhabited
that site before, I don't what content they might be blocking with me
not making a choice of cookie writes. Got a sample URL at their site
where not overtly accepting their cookie mandate would result in them
blocking my access to that content?

I'm tired, so I have not studied the rest of your post.
But on this part.

For me, that I don't block the banner, it is either accept all cookies,
or be forced to pay I think 1€/week to access. Otherwise, the site
simply displays nothing, the banner occludes all till you accept. Any
URL in that site.

What happens when you block the banner, no idea. Possibly depends on the
results, accepting or refusing banners.

Before this new system, that is, barely two weeks ago, I selected what
cookies to accept, which resulted in a lot of the adverts being empty.

Cookie law has changed in Spain about two weeks ago and many sites
changed their systems to this new one. Pay to remove cookies.

I take it Spain, or wherever the site is hosted, does not have to comply
with the European GDPR (General Data Protection Regulation) or the EPR
(ePrivacy Regulation aka "Cookie Directive").

https://gdpr.eu/cookies/
"What these two lines are stating is that cookies, insofar as they are
used to identify users, qualify as personal data and are therefore
subject to the GDPR."

Spain is a member of the EU, so they are under the jurisdiction of GPDR.
If the site claims otherwise, they are violating the law, but maybe the
site is not located in Spain.

https://gdpr.eu/cookies/
"Allow users to access your service even if they refuse to allow the use
of certain cookies"

For me, if there was no way to circument those assholes at their site,
I'd go elsewhere. Rarely is there content at a site that cannot be
found elsewhere.

When I attempt a WhoIs lookup on eldiario.es, I'm told that domain is
not registered. Yet I can do a "nslookup eldiario.es" (but that domain
is listed as an alias to aec01.usg.edgetcdn.io). A WhoIs on edgetcdn.io
says they're located in Madrid; however, "cdn" implies Content Delivery
Network. Those are used by sites to host resources for a web site. For
example, Microsoft likes to use Akamai.

The site is in Madrid. Spain is an EU member, so must comply with GDPR.
That means they MUST provide their service whether you allow their
cookies, or not.

What is this law in Spain that now defies the GDPR and ePR?

https://www.privacyworld.blog/privacy-europe/
Both the GDPR and the ePrivacy Directive (as implemented at national
level) apply to the European Economic Area (EEA), which includes all 27
EU Member States, as well as Iceland, Lichtenstein and Norway.

https://blog.didomi.io/en/all-you-need-to-know-about-cookie-consent-law-in-spain
https://cookieinformation.com/regulations/cookie-guidelines/spanish-cookie-rules/

Nothing is mentioned about allowing financial or content restrictions
when the visitor refuses cookies.

https://cookieinformation.com/regulations/cookie-guidelines/spanish-cookie-rules/
Regarding “cookie walls”, website owners still need to offer an
alternative for access to the service and functionalities without the
need for the user to accept cookies, but the new guide clarifies that
this alternative does not have to be free.

Ah, mention of punitive response by a site if you refuse their cookies.
So, accept their cookies, but delete on exit from Firefox. If they
write 3rd-party cookies, those will still be isolated to that domain
with Firefox's Total Cookie Protection. If you want to eliminate the
cookie banner on revisit, add an cookie exception for that domain.
