Firefox Support Forum

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?

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.

Best regards Andrew Sambrooks

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.

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.

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

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.

I clicked on 'block cookies' option( never seen this before but I trust you guys so....) when I logged onto firefox this morning, since then there are various apps I cannot get on to, eg Twitter, my banking through Nationwide, very frsutrating. So I tried to set a restore point prior to thios morning but that made no dofference, getting desperate now.

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,

I am having problems with some sites and the error seems to indicate that it is related to cookies.

In Google Drive, when I am trying to download any file, it is getting stuck in some kind of loop and at the end, it is showing this:

The page isn’t redirecting properly

An error occurred during a connection to drive.google.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

Apart from this, when I am trying to log into my Riot account in Valorant's website, it is ending up showing this:

Expected redirect cookie to exist

___

I have tried following:

• Using Standard mode for tracking protection
• Disabling tracking protection for these sites
• Deleting Cookies & Cache
• Reinstalling Firefox :(

It didn't help. Also, it started after I reinstalled Windows 11. I have yet to setup it, so I have not made any changes.

Also, everything is working fine in other browsers.

I recently switched over to using an SSD, and I am trying to do everything I can to prevent unnecessary writing to that drive. I've already found instructions for moving the location of Firefox's Cache files to my secondary HDD, but I haven't been able to do the same for Cookies; they're still being stored on my C: drive, in the AppData folder.

Is it possible to change the path that Firefox uses to store Cookies? If it is possible, how?

Despite have used Firefox for many years, I am still not completely clear on why there are two separate areas for cookie settings, and how everything works together. In Cookies and Site Data: I check Delete cookies and site data when Firefox is closed. In Manage Exceptions, the listed domains I choose will not be deleted, but all other domains will. Correct? In History: I uncheck Always use private browsing mode, and I check Clear History when Firefox closes. In the Clear Recent History box, I uncheck Cookies and Site Settings. Question: Will be above choices in both areas get me where I want to be, which is retaining cookies for chosen protected sites, while deleting cookies for all others whenever Firefox is closed? If this is where a lot of people want to be, why are these choices presented in such a complicated way? If relevant, under Enhanced Tracking Protection I choose Custom, and leave all the boxes checked. The sites I choose to use seem to perform well with this option. Is this Security & Privacy area in Settings in need of reworking for ease and clarity?

Very recently Facebook (META) wants me to agree to cookies before allowing me access to my personal page. There is a pop-up blocking access. (See attached screenshot) I have used Facebook container since it first became available. What is the risk here? At this point I have not agreed to anything.

I've just done a clean install of Windows 11 12H2 and, consquently, FireFox.

Don't know why I'm loosing all cookies when Firefox session ended.
