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?

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

We are having a problem with Kaiser Permanente’s website. The problem occurs randomly and when it occurs we cannot sign in to our account on the website. We get a “redirect error”.

We can fix the problem but comes back again after a while. To fix it we go to Settings / Privacy and Security / Cookies and Site Data / Manage Data. Under manage data we enter Kaiser in the search box and then delete the website.

Is there a way (a settings change) to fix this problem in Firefox or is it a Kaiser website problem?

BTW.. the same problem also occurs on Chrome, just not as frequently.

Is there a keyboard shortcut to remove cookies from the website? I mean the page I am currently on. And if there is no such shortcut, can I somehow create one myself?

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.

Our backend sets a cookie for maintaining login sessions with SameSite=None and Secure (to support loading our front-end from localhost for developers and from a third party domain for PR previews).

This is the respose header:

set-cookie: ESESSIONID=<redacted>; Secure; HttpOnly; Path=/; SameSite=None; Max-Age=86399

However, Firefox does not send the cookie back with requests, but logs this error in the console:

Cookie “ESESSIONID” has been rejected because it is in a cross-site context and its “SameSite” is “Lax” or “Strict”.

We have worked around the issue by configuring exceptions in the Security & Privacy settings, but I am curious to why Firefox rejects the cookie with this error message.

Recently, I cleared the cookies and site data from my browser as I'd noticed they were taking quite of lot of space on my harddrive. I thought clearing them would just reset them, but it looks like they were completely wiped instead.

Now, the browser never remembers any login information, so I have to connect to every site I use everytime I open my computer. It's troublesome when some of them have double verification and I have to go through the trouble of checking my email and entering a code everytime. The websites don't ask me to enable cookies again, so I don't know how to make them remember my informations again.

Is there a way to re-enable cookies, or have the websites ask me to enable cookies again?

Every time I try to log in to gmail I receive this message: We've detected a problem with your cookie settings. Enable cookies Make sure your cookies are enabled. To enable cookies, follow these browser-specific instructions I've tried enabling cookies in Mozilla. Apparently I'm doing something wrong because I'm still getting the same message from google.

I maintain application that uses OWIN Microsoft library for authentication. It uses .AspNet.Cookies to pass auth information. For unknown reasons I see that Firefox 127 rejects that cookie. I've tried with SameSite Lax/None/Strict and Secure param but no results. Previous versions and other browsers ( Chrome, Edge Safari ) woks fine. Any idea ?

I cannot use google.com without first deleting my cookies. This happens every time I try to use google. Doesn't matter if I use the taskbar to search, or try to go to www.google.com
