Hi Mozilla community,

The Developer Tools -> Storage -> Cookies pane shows cookies currently being stored by Firefox.

If I close my browser, these cookies are automatically deleted. However, if I follow the steps on [1], the cookies are still there, and don't get deleted. *Why?*

Thanks in advance!

Steps to reproduce:

- Start a new Firefox session
- Open Developer Tools -> Storage -> Cookies and see that the list is empty
- Go to youtube.com and click Accept All on the cookies popup
- Developer Tools -> Storage -> Cookies now shows a cookie from YouTube, as per the attached screenshot
- Go to Settings->Privacy & Security->Cookies and Site Data -> Clear Data -> Clear
- Go back to Developer Tools -> Storage -> Cookies and click on the refresh icon
- The YouTube cookie is still there
- However either of the following actions will correctly delete this cookie:

1) closing firefox (with Always Use Private Browsing Mode enabled) 2) manually deleting the cookie from the list in Developer Tools -> Storage -> Cookies

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

When I try to log into my website - https://huppbrian.us/tsc-admin - with Firefox Developer 111.0b8 (64-bit), get the following error first time every time... Error: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress. If I try again without making any changes, I'm able to log in fine. I've tried playing with the protections settings, but haven't found the magic pill to fix this yet.

How do I clear Cookies and other junk from Firefox please? Sorry I am clueless with all this technology, a technosaur. I am 73 yrs old, never studied computers, maybe one day I'll find time, between fighting other battles with baddies...

1. 1 I set the Manage Data tab to 'Allow' for sites I want cookies saved for. This sets the http and https addresses for the sites I enter.
2. 2 I set the same sites in the 'Manage Exceptions' tab so that these sites do not have their cookies deleted.
3. 3 Save Settings
4. 4 Close and re-open Firefox. All cookies are deleted.

I suspect this is a bug?

Cheers.

Hi, Today I discovered that firefox has logged me out of every site. I checked the cookies and there were cookies.sqlite and cookies.sqlite.bak. When I delete the newly created cookies.sqlite and rename cookies.sqlite.bak to cookies.sqlite, I am logged back in to all sites and everything works fine. I notice that the cookies.sqlite.bak file is created when I go to twitch.tv. Can I check what is causing this problem and fix it somehow? I've already tried deleting the cookies just from the twitch.tv site, but that doesn't help.

Hi there, I have configured Firefox to remove cookies after closing it. At the same time, I have added some webs that I usually use as exceptions, allowing to remember cookies in those. However, I have the following question: if I reject all cookies except for the mandatories ones in a website that I added to my "remember list", does that mean that future entrances in that web will be with only essential cookies?

As an example, if I mark https://www.bbc.com/ as cookies, and the first time I enter I reject all non-essential cookies, next times I enter in the bbc will I be navigating with only the cookies I accepted on this first entrance? Or allowing a site automatically accepts all cookies?

Thank you very much on advanced.

Even though I have removed the cookies for Facebook, the Manage Cookies screen shows a HUGE storage space. FF v99.0 on Mac

==

from preferences page: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space.

almost all are Facebook storage. I'm feeling a little reluctant to delete all site data. If I clear all cookies and site data will that fix the issue? will the issue re-occur?

Is there a Firefox setting that automatically clears cookies? When I turned my computer on, it had been cleared of cookies since the last time I had it on a few hours ago, but I didn't do it. No one else here to use the computer but me. I don't want cookies cleared automatically. How do I change it back to manual? I use Firefox Browser 120.0

thank you

How come when I have only cookies/offline website data checked to clear it still logs me out of websites like Twitter, Twitch, Youtube, etc?

Active logins and Site settings is UNchecked and yet it still logs me out. What is the purpose of those 2 boxes I may be misunderstanding them

about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla This ‘cookie’ (no size shown) has been showing up on my Firefox ‘manage website data’ since at least March ’23 and it will NOT delete. It may not be 'a real cookie' but I still can’t get rid of it.

When I searched online for that apparent address I found: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40175 The info near the top of that site’s page: Torbutton INFO: tor SOCKS: http://expyuzz4wqqyqhjn.onion/static/images/home/png/block-trackers@3x.png?h=70991bcb via --unknown--:cc55771ba6d6e8c6542066863a47e223 SOCKS is a username? And the ‘onion/hidden service’ address cannot be accessed unless using the Tor browser? So that seems a dead end for me.

I have seen 3 other people posting here in the past year about this particular cookie. hobro1 did an uninstall & still had to remove directories manually after getting some answers from several others. blazee decided – based on the answer given by jscher 2000 – that it probably wasn’t dangerous. mekishev 1 received an answer from cor-el that is incomprehensible to me, except for saying ‘it isn’t a real cookie’. I understand it may not 'a real cookie' but then why is it showing up in 'manage website data' where everything else is a cookie?

Can anyone help, please? I’m about to migrate over to a new computer and really don’t want to take this with me. I don’t like the fact that it persists, and that the cookies ‘keeper’ – SOCKS maybe? – is completely hidden.

Thanks much in advance for any assistance!

PS The only possible explanation I've come up with for how it got this cookie is when I was checking out some Firefox extensions; I didn’t even know what Tor was till trying to figure this out.

I watch videos on dropout.tv which uses the Vimeo SDK as their player for the videos. After switching to Firefox, the video progress has consistently started from where I left off on Chrome. The site doesn't remember where I ended the video when I watch it on Firefox. I assume this has to do with the cookies, but I've manually added "dropout.tv" to the list of exceptions in Firefox settings so that that site is always allowed to store cookies.

Returning briefly to Chrome, the player immediately tracked my progress again, so the issue is definitely related to Firefox somehow.

Firefox is deleting my website exception list whether I have "Delete cookies and site data when Firefox is closed." checked or not. It is the same with the exceptions list for logins.

I'm having problems with a website constantly asking me to accept cookie permissions. It happens on some other sites occasionally, but this particular site is one that I use each day.

When I visit the site I get the cookie permissions box. I click accept all cookies. No matter how many links I click I am presented with the box yet again. It doesn't happen with Chrome, Edge or Brave.

How to continuously reset history cookies/cache for one website.

Is there a way to continuously clear cookies and cache data for one domain or website? Or reworded, a way to not record cookies or cache data for one domain or website?

I have managed to find the article to clear cookies and cache data for the domain but have not been able to find out how to do this continuously without having to go into the settings each time to clear this history.

Kind regards
