Cookies being written and automatically deleted

Hello,

I work for Microsoft, and one of our sites offers users a way to opt out of personalized advertising on some Microsoft domains by setting a cookie. The site: https://account.microsoft.com/privacy/ad-settings/signedout

When the user clicks the toggle to Off, we cycle through four domains via an iframe and write a TOptOut cookie on each one. If everything is working properly, the user should then be able to go to www.bing.com and see a TOptOut cookie on Bing that will prevent personalized advertising on that domain.

The problem is, this stopped working in Firefox. We have verified that it still works* in 115.7.0, but in 122.0.1 and 123.0, the cookie is written and then deleted on refresh. If the user doesn't already have Bing open in another tab, they'll never see the cookie at all. I have verified this behavior in Bing several times, on my work machine (Firefox 122.0.1 on Windows 10) and my personal machine (Firefox 122.0 snap on Xubuntu 23.10).

  • It still works on our corporate VPN in 115.7.0, but not on my coworker's non-VPN machine. Same version. I'm really not sure what's up with that one.

This is a large concern for us. Because the cookies can still be written, it doesn't trip our test for third-party cookies being disabled. Because the cookie for microsoft.com is written, the toggle will show up as Off even after a refresh. This is misleading to our users.

I have gone over the Firefox docs on Enhanced Tracking Protection and Total Cookie Protection, but neither seem to handle this case. Firefox does not block any trackers on account.microsoft.com or on www.bing.com. It's fine if the cookies are in separate jars, we just want them to be written to the proper domains and not deleted. Can anyone tell me what changed in Firefox recently? Is this expected behavior, or a bug? If it's expected behavior, what can we do to allow users to opt out of personalized advertising?

Hello

I'm trying to sign into a Microsoft 365 email account but can't get beyond a screen saying "To use this site, you need to change your browser settings to enable DOM storage or cookies."

I've enabled DOM storage and cookies but no difference. I've cleared cookies and no help. I'm running Firefox 115.0.2 and Linux Mint.

Is part of the problem that I hate Microsoft and they know it?

Thanks

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?

As the subject says, I logged into my work gmail on my personal laptop, and since then my personal gmail (as well as every other gmail I used on this laptop BEFORE logging into my work one) is now under this Administrator, on all devices. I've contacted the IT department and they said they only had my work gmail under their system. More digging around and I found it to be a cookies issue, as Google Chrome (even after logging in and out of all my gmails personal and work) was absolutely fine and so was Microsoft edge.

No matter how many times I fresh install, clear cookies, or change settings in Firefox, my personal gmail is still locked under restricted mode. Linked below is proof that Google doesn't recognize my account under restriced mode, yet Youtube still says I'm being managed.

I would like my google accounts back, and if I have to wipe all my Firefox data and abandon it, I will. I just don't want to use another browser

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

I notice some problems with firefox since the latest update:

1. Right after the update I enabled the settings to empty the cookies each time FF is closed down ("Delete cookies and site data when Firefox is closed"). But, I ended not liking this feature since it constantly demanded me to remember my passcodes and became a headache, so I disabled it. But FF still continues deleting cookies each time, and seem to be stuck on deleting cookies.

I've been given various suggestions to go to resolve this, like reinstall, config, etc., uninstall apps, but nothing helps.

2. Another issue I have is FF with Facebook. Using Facebook in FF I can't backspace and I can't post any comment. If I try to post comments it simply moves the cursor down on the page but you can't post anything.

None of these issues continue in other browsers so it must be FF related.

3. FF seem to use enormous amount of memory and power usage, especially when multiple tabs are open (or even if tabs are not open it shows previous tabs in the Task Manager). I'm not a programmer or coder but a friend of mine who was a senior programmer in the banking industry told me it's possible for coders to solve this issue. If I understood him right (and I apologize if my wording is wrong), a solution would be to keep tabs in sleep state if they are open but not active on top so they don't keep running or updating data all the time. This of course would need consideration that sometimes people want to listen to videos or audio while using other tabs - but that would involve every single tab and can perhaps be provided as an option.

Many people like to keep multiple tabs open, yet still have good browsing performance. Maybe there can be a new project to offer better tab management to make them easily visible and accessible? Bookmarks are not that great because they disapper into a long stream of text without clarity what exactly they are until you open the page, and even then scrolling down and using bookmarks is not that great if you have many saved......

Firefox beta release: 116.0b6 (64-bit)

On sites such as BBC.com, Youtube.com and Facebook.com I am not getting the normal cookie consent pop-up option which used to automatically show on opening the sites. Other sites are still showing the cookie consent option pop-ups. This means I cannot select if I wish to accept or reject cookies on several sites that used to allow me the option.

In checking about:config, the cookiebanners.service.mode is set to 1, which I believe this the correct setting for enabling the cookies consent pop-up option.

Is there any fix for the cookie consent pop-up not working on certain sites within the EU? I am not using a VPN or pop-up blocker. Tracking protection is set to Standard, cookies and site data are always deleted on closing Firefox and "Do Not Track” signal is set to always. Deleting all installed FF extensions has no effect either.

In other browsers on the same PC, Chrome and Edge, the cookie consent option does still work as it should on the sites mentioned. In Firefox it doesn't.

This is only happening on one PC. My latop has the same FF beta build installed and is not showing this behaviour, it still automatically shows the cookie consent pop-ups when visiting sites such as BBC.com, Youtube.com and Facebook.com.

Hello,

When I sign in to new websites, they never do keep me logged in. I noticed this problem is present only for services that are working for my friends, that use other browsers, so they can keep users signed in. For the websites that I had been logged in before it stopped working, I'm still signed in and I can enjoy not having to log in every time.

I believe it all started happening when I cleared my cookies once, around half a year ago.

I did however check my settings, and I don't have selected option, that clears cookies after each browser session. My password saving feature works as well.

Every time I would try to log in it would always redirect me to a website that contain only the words "Expected redirect cookie to exist"

It's really annoying because it only happens on Firefox. For some context I just re-installed Windows 11 and I heard from another post that re-installing Windows 11 will help but I do not want to go through the whole process again.

I have already tried:
  • Turning off DNS over HTTPS
  • Turning Off Proxy
  • Clearing Cache and Cookies
  • Reinstalling Firefox

  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.
