Firefox refuses to delete cookes

Ref, firefox not opening homepage (google search).
Secondary problem is firefox refuses to remove cookies under Options/Advanced/show cookies/Remove all cookies.
Any suggestions??

Do you have an extension like TACO (Abine) that maintains a set of OPT-OUT cookies?
* Targeted Advertising Cookie Opt-Out (TACO): https://addons.mozilla.org/firefox/addon/11073
<blockquote>TACO with Abine prevents over 100 different online advertising networks (including Google, Microsoft and Yahoo) from displaying highly targeted advertisements using the detailed information on your web surfing habits. TACO disables most behavioral advertising by setting 100+ permanent, generic, non personally identifiable "opt-out" cookies directly into the browser. 
 
Unlike other opt-out solutions, this tool will make the opt out cookies completely persistent. That is, clearing the browser's cookies will delete all other installed cookies, except these.

Firefox won't delete cookies even after set to clear cookies on firefox exit

I have use custom settings for remembering history in firefox.
I set to clear history on firefox close. Under this settings, I set to clear cookies, active login and cache. But whenever firefox exits it doesn't remove cookies.
Also, I set to keep cookies till firefox closes. Still the cookies appears.
This is a big security issue for me..When I click restore previous session, firefox restores the login into sites also which I don't want

Got It!!!
Go To: Firefox/Tools/Options/Privacy/Tracking Checked box/Tell websites I do not want to be tracked/ History Firefox will: Never Remember History/ You may also want to: clear all current history/ Clear now/ click OK, ---> got it, that is your answer.<-- (Right click the left image below to open in a new tab)
And it is my answer as well, as I was confounded with this problem for some time. Now after you do this close your Firefox browser, and open back up Firefox browser, and there will be maybe only one or two cookies, depending on your browsers' home page.
I tried other methods to get rid of persistent cookies that would not delete by, CookieKiller, and TACO Targeted Advertising Cookie Opt-Out, those did not help, and I tried the methods listed on these links but they did not work:http://webdevwonders.com/clear-dom-storage/
Also this method did not work:http://justplainobvious.blogspot.com/2009/03/firefox-wont-delete-cookies.html
Next to make your Firefox browsing possible, go to/Firefox/Tools/Options/Privacy/,Tracking Checked box/Tell websites I do not want to be tracked, History Firefox will: Use custom settings for history, unchecked box Always use private browsing mode, unchecked box Remember my browsing history, unchecked box Remember download history, unchecked box Remember search and form history, checked box Accept cookies from sites, checked box Accept third party cookies, Keep until: I close Firefox, checked box clear history when Firefox closes, /settings all nine boxes checked/ click --->OK! (Right click the right image below to open in a new tab)
All Cookies are gone/history/deleted.

Bank claims firefox does not delete cookies although options set to do it

I use firefox 20.0.1. I set options to delete cookies when firefox closes. My bank claims to detect previous session cookies on my computer which were not deleted. Basically when their web site detects a new computrer for an account it requires an additional challenge question. I am not getting this expected challenge question. The bank is recognizing the computer although all cookies should have been deleted.

Are you closing all tabs with that bank site before closing Firefox?
When you reopen website automatically on a next start then Firefox will store cookies used in those tabs in the sessionstore.js file as part of saved session data, so you won't get logged off when you close Firefox without first closing those tabs.
If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox profile folder in case the file cookies.sqlite got corrupted.

Cookies turned on but Firefox refuses to accept cookies

Cookies are turned on in Firefox but I cannot shop through Firefox nor work in an online program, but I can in Safari.

Clear the cache and the cookies from sites that cause problems.
* "Clear the Cache": Firefox > Preferences > Advanced > Network > Offline Storage (Cache): "Clear Now"
* "Remove the Cookies" from sites causing problems: Firefox > Preferences > Privacy > Cookies: "Show Cookies"
If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted.
Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete cookies.sqlite-journal and cookies.txt, if they exist, in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case the file cookies.sqlite got corrupted.

Impossible to delete cookies, Cookie Culler, Mil Sheild, CCleaner, Spybot, Advance System Care, Firefox defeated them all.

I no longer trusted Firefox because of this. I even had difficulty uninstalling it; Windows, no; CCleaner, no, Advance System Care, yes. As I had much work to move favorites, etc, and found most extensions for Chrome I will not be going back. Seems strange as I have had Firefox from the beginning but I just couldn't get it to work on many sites and the steadfast refusal to remove cookies made me awfully suspicious. I think new versions were released too quickly, but what do I know?

Do you have an extension like TACO (Abine) or TrackerBlock that maintains a set of OPT-OUT cookies?
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Firefox no longer loads home page or deletes cookies. I have repeatedly checked both settings and they are correct. It always goes to the last page I was on when I closed the browser ..

In my experience this is most of the times a server issue of the website provider.
Does this error occur on all Websites or just one specific Website?
Does this Website load in Internet Explorer (or any other Browser?)?

Why has the option to delete cookies on quit been eliminated from preferences in Firefox 12

The "Privacy" preferences panel no longer offers the option to delete cookies on quit, as it did in Ffx 6, the version I updated from. Has this option been moved elsewhere? Has it been eliminated? If it has been eliminated, what is the last version that offers it? Could you please give me a '''specific, working''' URL where I can download the latest version that allows setting a "delete on quit" policy for cookies.
If Firefox puts the user first, why are your "updates" dumming down on user-settable options, especially one as important as an easy and convenient way to prevent cookies from hanging around till the next ice age. I realize I can manually delete cookies, but this is a pain in the rear, especially since I am missing most of my fingers. All those extra strokes that the ten fingered world dismisses as trivial really add up when you have only 2.5 fingers and one eye.

Your image shows "Firefox will Remember History".
It has a dropdown arrow which usually shows -
"Firefox will Never Remember History" and, what you need,
"Firefox will Use Custom Settings". This opens a range of options.
Is this pair of dropdown arrows not working?

I want to configure Firefox to only accept cookies from a specific list of websites, but my "Allow Exceptions" list is deleted when Firefox closes.

I want to configure Firefox to only accept cookies from a specific list of websites, but my "Allow Exceptions" list is deleted when Firefox closes. (Firefox 5.0)

@dmcritchie:
''How do you expect to keep cookies for certain sites, if you wipe out all of your cookies when the session ends or you clear the same history through the Tools menu''
If you mean from session-to-session, I don't expect it to keep cookies. That's the whole point. Every time Firefox is opened, I want it to write a new cookie, and keep that cookie until it closes and no longer than that. (Perhaps I should clarify: I don't mean session in the networking sense but rather in the period of time when one starts using Firefox until Firefox closes.) The behavior I want is for it to be able to write cookies when open, but only for specific sites, and then forget about them on close.
I should also mention that your responses are worthless to me because you don't explain anything. For instance, the quote above is ''not'' obvious from your reply of "Make sure you are not clearing cookies". You need to explain this; what is obvious in a reading for you is not obvious for everyone.
Furthermore, how is "Site Preferences" related to "everything on the right-side"? (Not to mention that it's unclear what you mean by "right-side.")

Why does firefox need to be closed to delete cookies & temp files

Only firefox seems to be this way -- under Windows, when I run a cleaner to delete temp files and cookies, firefox temp files and cookies can't be deleted unless firefox is closed. Can't this be fixed?

Other browsers don't seem to have his problem. i enjoy be being able to click on one item and having things cleared without fuss or bother. I'd prefer not to auto delete with each close nor do I want to have to manually hunt down with Ctrl+Shift+Del. I'm aware of those options. I was wondering why firefox still worked that way. Definitely a disadvantage for me using it. reminds me of the story:
A guy goes into a store to buy a suit and the clerk gives him one to try on:
Guy, "Hey one sleeve is longer than the other."
Clerk says, "Just shift your shoulders like this and it will look fine, see."
Guy, "But the pantlegs are uneven."
Clerk, "Well, just shift your weight onto one hip and, yes, see it looks fine."
Guy, "But the collar rides low on one side."
Clerk, "Here, hold that side in place with your chin against your chest like you're holding a violin. Voila!"
These accommodations go on for bit and the guy, somewhat exasperated but worn down, buys the suit. He wears it out of the store and down the street with his chin clamped to his chest, and one leg sort of dragging and his shoulder cocked, etc.
Two doctors walk past him and one says, "Oh that poor fellow," and the other says, "Yes, but he sure had a nice looking suit."

I programmed Firefox to delete cookies when I log off. Now Yahoo! won't remember me. How did I do it so I can go back and undo it?

I previously programmed Firefox to delete cookies when I log off. Now Yahoo! won't keep me logged on. Yahoo! tech said to restore cookie memory. I don't remember how I took that action. How can I go back and change that setting to retain cookies?

Tools > Options > Privacy > History > Custom settings
Accept cookies until they expire
(You probably don't need 3rd party cookies for remembering logins)

Does Firefox have a setting for retaining cookies similar to the 'Preserve Favorites website data' setting found in I.E. so you do not delete cookies from favorited websites when deleting your browsing history?

In I.E. when you want to delete your browsing history, the Internet Options tab allows you to retain the cookies for the websites that are listed in your 'Favorites'. With this preference enabled, you can delete your browsing history regularly without having to maintenance your cookies that you need. My bank requires that I register my computer for security reasons. The registration process places a cookie on PC. My browsing history is set to delete upon logout and I'm concerned that I will have to re-register my PC every time I log in or I will have to maintenance my browsing history every time I clear it. Does Firefox provide a feature so I can retain certain cookies that I want to keep?

If you use [[Clear Recent History]] or other means to clear (all) cookies then those specified cookies will be removed, even if there is an allow exception.
You can let all cookies expire if you close Firefox and make an Allow exception for the ones that you want to keep.
*Tools > Options > Privacy > Cookies: "Keep until": "I close Firefox"
*Tools > Options > Privacy > Cookies: "Exceptions"
Make sure that you do not use [[Clear Recent History]] to clear the "Cookies" and the "Site Preferences"
See also [[Cookies]] and [[Enabling and disabling cookies]]

Firefox doesn't delete my cookies when I clear all history.

When I go to options and clear all history (everything, all boxes checked), firefox does not delete my cookies because I am still logged into accounts. Not too sure about deleting all my history and cache either.
Is there a setting I am missing that bypasses certain accounts from getting deleted?

Is this about "Clear history when Firefox closes" to clear the cookies when you close Firefox?
If you leave tabs open when you exit Firefox then Firefox stores the cookies in sessionstore.js as part of the session data.
You can set the browser.sessionstore.privacy_level pref to 2 (never) or 1 (non-HTTPS) on the about:config page to disable saving cookies via session restore.
You can open the about:config page via the location bar

Firefox 10.0.2 doesn't delete cookies when Firefox is closed when selecting: Keep until: I close Firefox:

From the Menu bar select + tools + options + privacy + use custom settings for history + Keep until: I close Firefox:
Firefox 10.0.2 doesn't delete cookies when Firefox is closed when selecting: Keep until: I close Firefox: Please advise Thanks :)

If you change that cookie setting at a later time then only new cookies are affected and you need to remove already existing cookies yourself.
There are also extensions that add opt-out cookies that can't be removed as long as the extension is installed (enabled).
