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.

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.

Even though I have removed the cookies for Facebook, the Manage Cookies screen shows a HUGE storage space. FF v99.0 on Mac

==

from preferences page: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space.

==

almost all are Facebook storage. I'm feeling a little reluctant to delete all site data. If I clear all cookies and site data will that fix the issue? will the issue re-occur?

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.

suddenly Firefox is blocking my entry to a specific site with the measage "Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have tried umpteen ways around this to no avail. Google Chrome does not have this problem!! I am using version 100.0.2

How to continuously reset history cookies/cache for one website.

Is there a way to continuously clear cookies and cache data for one domain or website? Or reworded, a way to not record cookies or cache data for one domain or website?

I have managed to find the article to clear cookies and cache data for the domain but have not been able to find out how to do this continuously without having to go into the settings each time to clear this history.

Kind regards

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?

I would like Firefox to remember exceptions and store specific cookies that I need for the Microsoft authenticator, and other two-stage logins. Whatever setting I choose (untick delete cookiex and sitedata, assign websites to manage exceptions etc) upon closing Firefox everything is deleted, always. This means I can't use any authenticator to remember me when I want it to do so.

I used a third party cookie extension (Cookie AutoDelete) to whitelist some sites and it worked perfectly fine until an apparent recent update by Firefox. I am on Firefox 101.0.1 on Mac.

Any ideas?

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

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

Every time I turn my Laptop on and visit web sites I have to reset my cookie preferences to deny - I have other add-on's such as Privacy Badger, Adblocker, Ghostery, AdBlock Plus. Do I 'need' all of these? I'm a bit paranoid about security but also a tech moron....

How do I set to block all unwanted cookies and KEEP it set?

Many thanks!!

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:

• Block third party cookies
• Cookie tracking
• Cross-site tracking

Make sure cookies are not blocked and cross-sight trackingis enabled. Follow any additional instructions in your browswer once you have adjusted these settings"

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

Hi,

I'm using WhatsApp Web on the FireFox browser, I can't paste a website URL into the message line.

I can paste anything else - text, images,...

I do not encounter this issue while using WhatsApp Web on Google Chrome.

This is a new issue, I've been working like this for years and it srarted a couple of days ago. I cleared my cache, restarted the laptop and turned off add-ins.

Any ideas? Thanks, Gaby

Hi,

I am a developer currently working on an open-source solution called GeoNetwork (https://github.com/geonetwork/core-geonetwork/). This application has a Java backend that uses a JSESSIONID cookie to track user sessions. One instance of the application can be accessed anonymously here: https://sextant.ifremer.fr/Donnees/Catalogue

The session cookie is set on the first request to the backend with the following parameters:

Domain: "sextant.ifremer.fr" expirationDate: "Session" HostOnly: true HttpOnly: true SameSite: "None" Secure: true

This application theoretically allows login in from a different origin. For example from https://www.milieumarinfrance.fr/Acces-aux-donnees/Catalogue, which under the hood points to the same backend. We noticed recently that when accessing the application from a different origin in Firefox, the network requests aimed at the "sextant.ifremer.fr" host *do not carry any existing session cookie*, thus rendering authenticated access impossible.

The existing session cookie is correctly used when I add an "allow" exception for the sextant.ifremer.fr origin in the cookies settings of Firefox (see attached screenshot in French). So I figure that it's Firefox that decides not to use any existing cookie when on this origin.

Is there any way to indicate to Firefox that this cookie is legitimate and that it is needed for essential functionalities, without relying on the user allowing the cookie explicitly?

Thanks a lot in advance!

When I go to clear the cache, browsing history, cookies, etc. the only options we have are "Today", a few even smaller time periods (1, 2, 4 hours), or "Everything"! What's up with that? Every other browser offers at least the option of "past 7 days" or some other time period that goes further back than one day, without having to clear "Everything", don't others find this to be arbitrarily limited? I can't even delete cache from yesterday, much less a few days earlier...

I just create a website that is providing the Latest Menu in Malaysia (mlymenu.com). I optimize my website Core web vitals but its still slower in Chrome and faster in other browsers. I also clean cache and everything. Even on other deivces too. I think there is some issue still in chrome. You need to update it

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,

I have been using Mozilla Firefox for years. I am using the latest version (121.0 (64-bit)). Suddenly today, several websites result in a blank screen (startme and nextdoor) and other pages will not let me login (Citi, Edelman Financial Engines). I tried deleting the cookies and site data and history but it did not help and might have made it worse. When I tried to login to Mozilla support, it says I need to enable cookies and will not let me login. When I go to "Settings-Privacy & Security", it is set to "Standard" which is supposed to include allowing cookies. If there is another place to enable cookies, I do not know where that is.

If I use Microsoft Edge, all the webpages work normally. I had to post this message using Edge because I cannot login to Mozilla using Firefox.

I have many bookmarks saved so I hope whatever the solution is will not lose them.

Thanks to anybody who can help me fix this problem
