Firefox Support Forum

Hi,

We have an application where we do not want to share the session cookies between tabs. Is this possible? If above answer is yes, next we would like to filter out some cookies by name that should not be shared across tabs. Meaning, we want some cookies that can be shared across tabs and some should not be shared.

Thanks in advance

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

Hi I am trying to visit a website but It is showing an error I am not sure why The website says that

Your browser did something unexpected. Please try again. If the error continues, try disabling all browser extensions.

Is there any browser issue because I am not using any extensions or ad blockers?

Is AdBlock part of your system? I inquired about their ad and declined. Since then they have become an absolute "PEST" popping up in every thing I do. Your logo appears in their Ad.

On our online application we are facing with some strange behavior for a small percentage of our firefox users (<1%).

When doing oauth2 authorization, after generation of the authentication token we redirect to another platform but we are detecting that for a small percentage of Firefox the cookie (my_auth_cookie) with the auth token is not present.

GET: https://www.mywebsite.com/application/login Response:

new location https://www.mywebsite.com/otherapplication/redirect

set-cookie: my_auth_cookie expires=Mon, 04 Dec 2023 13:49:15 GMT; domain=.mywebsite.com; path=/; secure; samesite=lax; httponly

      2. GET https://www.mywebsite.com/otherapplication/redirect

          Set-cookie: mycookie: value

          Host: www.mywebsite.com

In cookie tab I see my_auth_cookie (value: xxxx, domain: .mywebsite.com, expires: Mon, 04 Dec 2023 13:49:15 GMT, httponly: checked, secure: checked,SameSite: Lax, partitionkey: empty, Priority: medium

I’ve tried to replicate but without success (with multiple extensions, including multi-account containers), with multiple configurations of Total Cookie Protection.

Again, this only seems to be happening to a very limited number of firefox users but for these, it happens 100% of the time. We see it occurring for versions 119 and 120 but now and then for older versions.

Feedback reports no extensions&addons.

Any ideas on what we could be dealing with? Any help would be greatly appreciated.

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.

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...

website for example like VK - https://vk.com i can't never sign in/log in.. it keeps telling me The page isn’t redirecting properly An error occurred during a connection to login.vk.ru.

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

i tried to - delete cookies - delete history - add exception (vk.ru/vk.com) to Cookies and Site Data - private Mode - disable HTTPS-Only Mode - reinstall firefox but still like some other website the same problem.... plz help these websites work fine -- by using other Browsers i can login

I've tried other browsers (e.g. brave) and it works fine there. I can close the tab, close the browser, reopen it and I'll still be logged into chatgpt but not with firefox

I've tried clearing cookies, settings them to always be allowed, re-enabling web-rtc, disabling enchanced protection, nothing works. IF i close the active tab with chatgpt even momentarily i will always have to re-log in again when i reopen it

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.

Good morning I would like to ask how to configure (set) the Firefox browser on a computer with Windows 10 so that when clearing cookies and history, cookies and login data that have been added to exceptions are not cleared (deleted) when closing the browser: How this setting should be done (what options are selected) Privacy and security - clearing history when closing the browser Privacy and security - deletion of cookies and site data on closing (exceptions - allow) Please reply Regards Zbigniew M zbigniew14@gmail.com

I haven't deleted my browsing history since 2021 September, but I wish to restore browsing history from 2021Jan-2021Sep for some reasons.

I am using mac, latest version of macOS and latest version of firefox. I have read some similar articles (https://support.mozilla.org/fy-NL/questions/1290163) but it doesn't help. It says I need to go through "Start" > "Search" > "Tools" > "Folder Options." . I cannot find folder options, and I cannot find index.dat inside my mac. What can I do ? Any help is appreciated.

I see a similar question on the forums from March 2021, but I'm having this problem now: when I go into icloud.com, it keeps asking for authentication - i.e. it presents a 6-digit code which goes to my phone/ipad, and I have to put it into the browser. After that, I'm prompted "Do you want to Trust this browser" to which I ALWAYS say "Yes", but it doesn't seem to work; the next day, if I try icloud again, it does it all over, like the "Trust" option is ignored. In settings, "Delete cookies and site data when Firefox is closed" is unchecked, Clicking "Manage Data" shows that cookies for icloud.com are saved. I've just added icloud.com into Exceptions to Allow to use cookies/site data, though I wouldn't think I'd NEED that if I'm never deleting them. I tried this with Chrome, and the Trust DID work; I can sign in with that browser and not have to put in the code.

What's up with that?

After an update, cannot use my online banking fully. Get the error: "Why can't I access Bill Pay?" "You might have cookies blocked or cross-site tracking prevented. Depending on what browser you are using, check you settings for these terms:
