Diễn đàn hỗ trợ Firefox

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?

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

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......

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.

I switched from chrome to firefox like 2 days ago. Everything went good, but every time i go to youtube it does not remember my login. I have to click the login button and use my phone to confirm the login. Afterwards i get send to an error page only saying "something went wrong". If i click the login button again it suddenly works and i can use my youtube like i used to on Chrome. I use my google account for youtube. Every other login works just fine Reddit, Disney+, Twitch, Prime. I Cleared all my cookies and history and even reinstalled Firefox. only youtube still has this problem. I even added the youtube and google login page to the saved logins. Does someone can offer any help ?

Regardless of what I have tried i still have:

Cookies and Site Data Your stored cookies, site data, and cache are currently using 218 kB of disk space.

Iam using: History Firefox will Firefox will remember your browsing, download, form, and search history. Always use private browsing mode

Firefox is u to date I have restarted ....

Thank you for help - Nicolas

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

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.

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.

Although I allowed google ads (shown in "Not Blocking Tracking Content" list), they are still blocked. Is there a way to fix this? This problem appears on two sites (https://www.agame.com/game/tropical-merge, https://www.games.gr/paixnidia/the-mergest-kingdom) only. Other sites work as they supposed to. ABP is disabled. If I turn Enhanced Protection off, I can see google ads, but I lose any progress I have in these games. Any help would be appreciated.

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.

Why do Cross Site tracking cookies show up after I shut down the browser and restart? I have my history set up to delete everything when I close the browser so I'm curious why cross site cookies are apparently allowed to exist/function, even after a restart?

Could you kindly advise? WashingtonPost.com does NOT ask to accept cookies even after I deleted all cookies, website data and cache (but in Opera it does ask for cookies), after Firefox automatically deleting cookies and website data after closing Firefox, and after cleaning cookies, website data and cache with Ccleaner — WHY? Which mechanism of Firefox is exploited by WashingtonPost.com? And what should I do? Thank you!

Getting following when trying to access my e-mail not having the problem on edge but Firefox is my go to browser

I keep getting signed out of my Google account whenever I close Firefox. I switched the Enhanced Tracking Protection to Standard, and I do not delete my cookies when I close Firefox. I even tried to disable the Purge Trackers option but this didn't help either. I have some dev-tools extensions installed + Adblock and Decentraleyes. It does not solve my problem if a disable them too. Would really appreciate anyone's insight.

We use FireFox 118+ . our product needs to collect all cookies, including 3rd party cookies from any domain loaded.

* We have turned off "Total Cookie Protection" by selecting Custom privacy settings and un-checking all check boxes (sceenshot attached)

• Also turned off "Enhanced Tracking Protection" for the website

But, when we browse to any site, the collected cookies under cross-domain are either empty or less compared to chrome.

Is there any other setting we can use to collect all the cookies ?

ex domain : https://www.santander.com/es/home , if you compare the cookies collected with chrome are much more than whats captured in FireFox.

Please help, this is crucial

Thanks,

The past few days when i've tried searching for certain pages i go to all the time they won't show up under "firefox suggest" then when i check my history for them the pages are just completely gone, today i checked my history for yesterday and even though i started browsing at 8:00 the history only went back to around 13:00 with all the pages before that completely gone, this also causes me to lose all the cookies as well.
