Firefox not clearing cookies!

Firefox 19.0.2 running on Windows Vista
Firefox 19.0.2 is NOT clearing cookies Tools->Clear Recent History is selected. I have been using Firefox for 9 years now and it keeps getting worse and worse. I know how to clear cookies as I have done it thousands of times. Imagine my surprise today when I went to Google and fount out I was still logged-in from earlier because my cookies were not cleared when I thought they were cleared as they used to be.
I do not like being tracked on the internet. I browse some websites, clear the cookies, disconnect and reconnect to the ISP to get a new IP address. I am not interested in any other non-solution solutions. What I want is for this BUG to get fixed. And it is clearly a BUG because other people are complaining about it.
Can you imagine the security implications of using Firefox when it does not properly clear cookies when people think it does???
Another thing that really bothers me about version 19 is how Firefox hides cookies from you when you are browsing in Private Browsing mode. When using Private Browsing, if you go to Tools->Options->Privacy->Show Cookies it shows only cookies from Google but not the websites you have viewed directly making it appear that no cookies are set when they are. You have to exit out of Private Browsing, Clear Recent History (if it works!) and then re-enter Private Browsing to continue. Think about a news website that limits you to 10 news stories by using cookies. I used to clear the cookies and continue reading the news. I can't do that anymore without exiting out of Private Browsing first. But now that I have discovered that cookies are not being deleted anymore using Clear Recent History, I guess that won't work either.
Who could possibly think hiding cookies in Private Browsing mode was a good decision? Why would you hide anything from the users of Firefox?
Also, I have noticed on some webpages with a lot of images that a black bar stretching the full width of the browser and approximately 50 - 75 pixels high will appear over the rendered page. It disappears when the page is scrolled.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.

What's the difference between keep cookies until I close firefox and clear cookie history when firefox closes?

In the settings for Firefox 33.0 (I am using Ubuntu 14.04 but the functionality is the same for Windows 7) there are two different ways to delete cookies when firefox closes. Or at least there seems to be.
First is the keep cookies until firefox closes
Second is to check the box to clear history when firefox closes and in the settings check cookies.
What is the difference between these two options?
I usually have both setup but I was noticing that a login was not saving for td canada trust easyweb, even though I have an exception set for it. Now I unchecked to delete cookies when clearing the history on close and the login saves correctly.
This login saves 7 cookes under easyweb.td.com and 10 cookies under td.com and I have exceptions set for both. If I clear history on close and include cookies, half of the td.com cookies are gone when I close firefox and re-open. The same is true if I don't set the exception.
So currently I cannot figure out a way to keep all the cookies if I clear cookie history when firefox closes. What is the difference when this is enabled?

Let all cookies expire when Firefox is closed to make them session cookies.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Keep until: "I close Firefox"
Create a cookie 'allow' exception for cookies that you would like to keep.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions
Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception that you would like to keep.

Why Firefox automatically clearing cookies/cache?

Recently Firefox has been automatically clearing all log-ins and passwords on a seemingly random basis.
After closing a browser window, I launched Firefox, and all of my standard logins (emails, homepage, etc.) have been cleared. This has happened 3 times now at seemingly random times. I'll go for weeks without an issue, and at one point open a browser and everything is logged out. This is after a successful close - no error shutdown, same day as other uses without issue.

Why does the new Firefox not save cookies of previous stock quotes on financial sites?

Firefox no longer saves "previous quotes" for stocks on any of the financial sites.

Firefox will not open now - I just updated my privacy settings, and cleared cookies - what happened?

I changed the privacy settings on Firefox preferences, including clearing cookies, history and cache, and now Firefox will not open at all. It said it had to restart after one of the privacy changes, but it didn't and now won't open by the dock icon or thru applications. What happened, and how can I correct the issue to start using Firefox again? Thanks.

Cache, cookies and history are not clearing when I close Firefox even though they are set to do so and have been for ages

I recently had an update (or upgrade?) for FF 16. Today (and I believe the update was done a day or two ago?) my cache, cookies and history are not clearing when I close FF. Also, certain links are not working. Not links for full web pages but for site pop-ups (like the smilie window on a message board). They worked a few days but are not working today. I click the link and nothing happens. I noticed the problem with the cookies not clearing for a few weeks ago but it was only on one site not all sites which is what's happening now.
My apologies if that's a little confusing. Thanks!

At any rate, have you tried running Firefox in Private Browsing mode? This will ensure that no infromation from your session is saved once you exit Private Browsing mode and/or exit Firefox.
You can set Firefox to always start in Private Browsing mode: https://support.mozilla.org/en-US/kb/private-browsing-browse-web-without-saving-info#w_how-do-i-always-start-firefox-in-private-browsing

Even though I have ordered Firefox to clear my entire browsing history and cookies when it closes, it is not doing so when I exit. I have to manually clear the history and cookies each time.

I am running Firefox 10.0.2 for Linux, and have never had this problem with previous versions. I wonder if it is an issue of Firefox not quitting completely when I close it...meaning it would not clear the history and cookies because it is not technically shut down. This is just a theory, however. Any help would be appreciated!

Thanks for the suggestion. I made sure the prefs.js file had read and write permissions, and since then it seems to be saving my settings and deleting all the information I ordered it to on exit.
Thanks for your help! This was a minor problem, but it's nice to know that everything is working the way it's supposed to now.

As of 2/19/12 I could open two independent firefox windows and they did not share cookies. As of now (2/23/12) if I open two independent firefox windows they do share cookies. How do I get them to stop sharing cookies?

When google decided to change their privacy and sharing policies I started using two different windows to do all internet browsing and work. I would open my gmail in one window and then do everything else in another window so that google couldn't tie my searches and other internet activity together with my google accounts.
This process was working well for me until about three days ago, when all of a sudden my two Firefox windows started sharing cookies. I know for a fact they had not been sharing cookies previously because I personally go in and clear them after I visit certain websites.
From my research on this issue it seems that in the past this was the default way all firefox windows operated (sharing cookies with one another), so I don't know why I managed to get several weeks of not sharing cookies and suddenly they are sharing. But I just want to go back to the way it was just this weekend. Please help or I'll be forced to use IE and that would be sad.

Firefox stores cookies on a per site basis.
I am guessing that what you are seeing is that Google is sharing cookies across its own sites.
It is possible (an advanced subject not normally covered in this forum) to open multiple instances of Firefox with separate profiles, and thus separate cookies. A more normal method of achieving that is to use a separate user OS account. Or possibly to use firefox portable.
I have not myself followed news of Googles cookies policies, but I see it is in the news again http://www.theregister.co.uk/2012/02/22/ico_enquires_about_google_system_for_serving_third_party_cookies/

Since I did the Firefox reset, I try to open my email and it says, Your browser does not accept cookies. I have checked the cookies setting 100 times!

Since I did the Firefox reset, I try to open my email and it says, Your browser does not accept cookies. I have checked and done your suggested setting 100 times!

Note that a reset tries to migrate cookies to the new profile, so if you had previously as problem with cookies then the problem might have been carried over.
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.

I'm having a problem where Firefox keeps asking for my Amazon password, even though I tell Firefox NOT to remember this password. In Firefox options, Amazon is clearly listed as a site for which not to save passwords.

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.

Firefox will not allow cookies?

I'm really not sure what's going on with my Firefox. I'm trying to use Google Scholar and it keeps telling me that I need to enable cookies to use it properly (add libraries, change settings etc).
By default, my cookie settings are:
Use custom settings for history > Accept cookies from sites > Accept third-party cookies (From visited), Keep until (I close Firefox).
And I've never had a problem with that before. But no matter what I do now, I can't get it to work...
THINGS I'VE TRIED (in no particular order):
- Changing cookie preferences to: Use custom settings for history > Accept cookies from sites > Accept third-party cookies (Always), Keep until (They expire).
- Clearing all cookies and cache (via clearing history)
- Clearing cookies individually: Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
- Clearing the Cache: Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
- Resetting Firefox
- Deleting cookies.sqlite from my profile
- Clearing history for that site: https://support.mozilla.org/en-US/kb/websites-say-cookies-are-blocked-unblock-them#w_clear-history-for-that-site
I'm at a complete loss. Despite all of this it STILL tells me I need to enable my cookies...Is there anything that anyone can suggest to me to fix this??

You can inspect and manage permissions for the domain in the currently selected tab via these steps:
*Click the "[[Site Identity Button|Site Identity Button]]" (globe/padlock) on the location/address bar
*Click "More Information" to open "Tools > Page Info" with the Security tab selected
*Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab
You can try to clear the Site Preferences or possibly rename or delete the permissions.sqlite file.
*https://support.mozilla.org/kb/remove-recent-browsing-search-and-download-history
Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
You can also try to access the website in New Private Window.
You can check if DOM Storage is enabled.

Despite settings, firefox does not clear history.

Had this problem with vista and now with windows 7 (full instal - not upgrade) - Security settings for firefox are to wipe everything when closed - firefox32.exe hangs when program closed and history (etc) is not cleared. System is 64 bit. Possible causes (symptoms I've noticed) are - MTV stream open when computer rests - divx or megavideo stream open when computer rests - none of these things work everytime so it's hard to tell what causes it - has been a problem with two versions of windows.

The sessionstore.js file that stores session data includes cookies from open tabs, so if tabs are restored and you haven't logged out then you may still be logged on unless the session has expired via other ways.
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 in the sessionstore.js file.
The browser.sessionstore.privacy_level_deferred pref is used when you do not reopen the previous session automatically via "Show my windows and tabs from last time" and uses the same values.

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.
