Hi,

I'm developping a custom tool in order to automatically clean my cookies from several websites. For example, I would like to automatically remove cookies from twitter.com every time I launch my tool. I'm under Win10x64, firefox v89, tool developped in python.

To do this, once firefox is closed, my tool go in my profile folder, access to cookies.sqlite and delete row associated to twitter.com

-> DELETE from moz_cookies WHERE host == '.twitter.com';

The database is saved, no more "twitter" in my cookies.sqlite file, and the tool ensures there is no cookies.sqlite-wal or cookies.sqlite-shm files left.

After that, when I open again twitter, I am no longer connected to my session, but I got an error which seems to be related to cookies (see screenshot).

Moreover, when I oppenup the firefox cookies manager, there is still twitter cookies in the list, but 0 cookies associated.

Where is my mistake ? Can you help me solve my problem ? Thanks

I know that clearing browser cookie regularly is a good practice, but I am a bit curious if clearing out those session cookies is the same as if you log out of all the accounts manually.

Because logging out manually will make both local and server side session cookies invalid, thus log out safely.

Meanwhile clearing browser cookies only delete local side session cookie, while the session cookie on the server remains. Which means the session is still valid.

So do I clear browser cookies or log out manually if I want to log out of all accounts?

I have noticed that when I manually log in into accounts.google.com with no prior cookies in the browser and no association with a google account prior to that, it automatically logs me into sites like youtube.com, even with the strictest cookie policies (tried with Strict, custom+cross-site and custom+third-party). I do not particularly mind privacy wise since I'll log into them with the same account anyways, but as far as I understood, there should be absolutely no way this should happen. Cookies should be isolated by domain, I have uBlock Origin installed which prevents cookie sharing between domains by setting some CNAME records in subdomains (Uncloak canonical names), and afaik Firefox does not automatically read the google account cookies and share them around - if it did, that would be even more serious. So what is happening here and how can I change that? This seems to be a serious issue that I'm honestly not comfortable with out of principle since I chose the strictest settings.

Hello Since version 89 my cookies are not kept anymore. I have set Firefox to delete cookies when closing but I have set exceptions for some websites to keep the cookies. Also I delete the history when closing except cookies. (This setting was chaged after updating to version 89)

With this settings Firefox kept the cookies of the exception websites But since version 89 all cookies are deleted, also those for the exception. Any new setting to do? Regards Oliver

Edit: Rewritten from scratch on Wednesday, June 16, 2021:

I am running the new Firefox 89.0 on Linux. Under the Edit menu, the Preferences option is now called Settings.

Please open Settings and search for site data. This displays the pertinent settings for Cookies and Site Data, and for History.

A Web SDR site is a website that gives each of its visitors the ability to tune a Software Defined Radio chip to a different frequency, independent of other users' listening preferences. The audio is streamed back to the user.

It requests that the user supply a user name, often a ham radio operator's callsign. This is used to display on the radio dial where each user is listening. If a name is missing, the user's IP address is used.

A cookie is stored with the user name, and if that cookie survives to the next visit to the site, the name does not have to be re-entered.

The web SDR can allow users to save custom memory presets, and cookies are said to be used to save memory presets "on your computer," and not on the server.

I had set cookie preferences for each site to always allow cookies, and my username was indeed carried over from one browser session to another. But my presets were never saved.

I finally discovered that it was not a cookie, but offline site data storage on my computer that retains these presets.

Under the History section in Preferences of earlier versions of Firefox, I told Firefox to use custom settings, and then I had set first- and third-party cookies to be allowed for the session. I told Firefox to Clear history when it closes, and in the "Settings ..." dialog, I unchecked everything but cache and offline site data. Only cache and offline site data were deleted.

The History section in Settings in FF 89.0 is still set for Firefox to use custom settings, but cookie options are not listed. I still tell Firefox to Clear history when it closes, and the "Settings ..." dialog is the same.

In the Cookies and Site Data section in Settings, I tell Firefox to Delete cookies and site data when it is closed. In the "Exceptions ..." dialog, I enter the address of the website and hit "Always" for everything entered, to save the site's cookies and data from the bulldozer.

It occurred to me that there are two duplicate means to clear cookies and site data.

I went to History and opened the "Settings ... " dialog again and cleared the checkbox for offline site data.

NOW my stored memories on the Web SDR sites are still here! In Firefox 89, do not use History's Clear history when Firefox closes to delete cookies or site data, for that will blow away the cookies that were saved in the Cookies and Site Data's Exceptions!

The browser was overhauled, and History's handling of cookies and site data became obsolete.

I do have a question here: If I am on a site, I can click on the lock in the address bar to retrieve a series of screens that lead me to the Security tab, and to its left, the Permissions tab. By selecting the Permissions tab, I can set the site's permissions for cookies and for persistent storage of site data.

If I set to allow cookies and allow site data in Permissions, does that enter the site address into the Settings' Cookies and Site Data's Exceptions dialog? Or must I still copy the address of the site and go to Settings and enter that in Exceptions also?

When i am opening up firefox it loads the last session (as it should), but it opens old cached versions of them all, instead of loading them again. Even when i have cleared all cache and cookies data. Even tried refreshing pages. OPening up in incognito mode nothing works on my PC but the mobile phone on the same wifi network serves the new website ..

Even tried solutions mentioned on [thread ] but it didnt seem to work

Ububtu 20.04 LTS

I want to disable cookies for certain website. For example allowing cookies from google and disabling cookies from quora. I don't want to disable cookies from all websites.

I put items in a cart on a website that I accessed through firefox. I did not sign into any accounts on the website and I did not purchase the items. I then cleared my cookies, cache, and offline data. Later on I went back to the website and wanted to put items back in the cart to re-price everything and discovered that the items were still in the cart from before. I cleared cookies, etc. again and the items were still in the cart. I then went to the website on Chrome and the items were still in the cart. Again, I did not sign into any accounts or anything. I never use Chrome. Just went straight to the website on Chrome and went to the cart and the items were there even though I didn't use Chrome to put anything in the cart. I then cleared cookies, etc. on Chrome and the items were still in the cart. I tried this on Edge and same thing. I have used Bitdefender, Malwarebytes, Hitman Pro, and CC Cleaner and no program is finding the malware or spyware or trojan or whatever this is. This is a well-known website that even has a facebook page. I messaged the webmaster and I posted on their facebook page and I'm being ignored. What is this and how do I get rid of it?

I have 3 accounts on a particular website. All three account login credentials are saved in firefox however one of them (the wrong one, since it is the one I use least often) is pre-filled when I first go to the site. How do I remove the setting that one of them is pre-filled? I want just the regular drop-down choice of all three. I have deleted that accounts credentials and cleared the cache, but as soon as I add the account info again, it is automatically pre-filled instead of just listed with the other two options.

I cannot get access to my Bank-account. Possibly the cookie are reponsible.I would like to get a hint for deleting the cookies ??!! I get always the Remark/Answer : Access denied.

I'am hoppeful You could help me.

Urgent!!!
