Diễn đàn hỗ trợ Firefox

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

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.

Hello Is it possible to get Firefox to clear cookies at the close of Firefox but still keep forum login details and not delete forum login data. Help appreciated Thanks

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!!

For some reasons which I don't know, all of my cookies got deleted several times. I need to find them, How can I find my past cookies with the help of sync system? Details: It seems the site: telegra.ph uses only cookies for the ability of edit a page by creator person, with no password, signup & signin. I need to find my cookies so that I can edit my created pages again. Also I need to can use those files in other devices, After find them how can I have that files to use in other computers except using sync.

I manually delete cookies at the end of the day, and after the latest update it shows 13.0kb left after deleting. I have no exceptions or any other setting other than to delete ALL cookies. I can not find what this 13.0kb is and why is it still there after deletion? Windows 10.

about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla This ‘cookie’ (no size shown) has been showing up on my Firefox ‘manage website data’ since at least March ’23 and it will NOT delete. It may not be 'a real cookie' but I still can’t get rid of it.

When I searched online for that apparent address I found: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40175 The info near the top of that site’s page: Torbutton INFO: tor SOCKS: http://expyuzz4wqqyqhjn.onion/static/images/home/png/block-trackers@3x.png?h=70991bcb via --unknown--:cc55771ba6d6e8c6542066863a47e223 SOCKS is a username? And the ‘onion/hidden service’ address cannot be accessed unless using the Tor browser? So that seems a dead end for me.

I have seen 3 other people posting here in the past year about this particular cookie. hobro1 did an uninstall & still had to remove directories manually after getting some answers from several others. blazee decided – based on the answer given by jscher 2000 – that it probably wasn’t dangerous. mekishev 1 received an answer from cor-el that is incomprehensible to me, except for saying ‘it isn’t a real cookie’. I understand it may not 'a real cookie' but then why is it showing up in 'manage website data' where everything else is a cookie?

Can anyone help, please? I’m about to migrate over to a new computer and really don’t want to take this with me. I don’t like the fact that it persists, and that the cookies ‘keeper’ – SOCKS maybe? – is completely hidden.

Thanks much in advance for any assistance!

PS The only possible explanation I've come up with for how it got this cookie is when I was checking out some Firefox extensions; I didn’t even know what Tor was till trying to figure this out.

After updating to version 112 from 111.0.1 Firefox keeps forgetting logins and cookie settings on all websites. After closing and reopening the browser I have to sign in again and the websites will ask for cookie permissions.

I tried reverting to 111.0.1 and creating a new profile and it did not have the same issue. I also tried disabling all extensions in version 112, but that did not help.

This issue seems to only occur when I try add videos to a playlist via the following.

Login>studio.youtube.com>content>playlists>selectlist>EDIT in YOUTUBE> 3 dots>add videos - issue emerges Work-around in Chrome.

Can add to playlist from the video if option (3 dots>save) is there.

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

I checked cookies and data recently and noticed this cookie listed about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla and I cannot seem to delete it I think it appeared when I accidentally clicked reader view what is it? I tried searching and found a similar question https://support.mozilla.org/bm/questions/1372671 and google search seems to mention tor for some reason any help please?

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?

Please help me understand why there is a feature to have cookies be made exceptions from deletion and then when someone elects to delete all data, cookies, and browsing data on exit....the EXCEPTION list of cookies also gets deleted.

Starting this week, I can do only one search for a movie title on Metacritic.com. I get a 403 error from any attempt to do a subsequent search. I can get one more successful search if I first delete my Metacritic cookies from Firefox. But the problem repeats after any successful search.

Repeated searches work fine if I access Metacritic via Chrome. In case it matters, I'm running both browsers under Windows 10 on a desktop.

Can I tell Firefox not to accept cookies from Metacritic? Other ideas?

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?

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!

I have Firefox 99 for Mac "Delete cookies and site data when Firefox is closed" is unchecked History is set to "Remember History" Enhanced Tracking Protection is set to "standard"

Yet every time I return to a site where I've checked "remember me" , I'll get prompted to login, and perhaps also get a security message "you've logged in from a new computer" in my email from the site.

Is there an easy way to verify that Firefox is storing cookies for a site. Maybe an option to right-click on a site's web page and view "cookies are stored for this site" in the context menu? I'm losing a lot of my productivity time logging back into sites that I just logged into earlier in the day.
