Firefox Support Forum

Hello,

I work for Microsoft, and one of our sites offers users a way to opt out of personalized advertising on some Microsoft domains by setting a cookie. The site: https://account.microsoft.com/privacy/ad-settings/signedout

When the user clicks the toggle to Off, we cycle through four domains via an iframe and write a TOptOut cookie on each one. If everything is working properly, the user should then be able to go to www.bing.com and see a TOptOut cookie on Bing that will prevent personalized advertising on that domain.

The problem is, this stopped working in Firefox. We have verified that it still works* in 115.7.0, but in 122.0.1 and 123.0, the cookie is written and then deleted on refresh. If the user doesn't already have Bing open in another tab, they'll never see the cookie at all. I have verified this behavior in Bing several times, on my work machine (Firefox 122.0.1 on Windows 10) and my personal machine (Firefox 122.0 snap on Xubuntu 23.10).

• It still works on our corporate VPN in 115.7.0, but not on my coworker's non-VPN machine. Same version. I'm really not sure what's up with that one.

This is a large concern for us. Because the cookies can still be written, it doesn't trip our test for third-party cookies being disabled. Because the cookie for microsoft.com is written, the toggle will show up as Off even after a refresh. This is misleading to our users.

I have gone over the Firefox docs on Enhanced Tracking Protection and Total Cookie Protection, but neither seem to handle this case. Firefox does not block any trackers on account.microsoft.com or on www.bing.com. It's fine if the cookies are in separate jars, we just want them to be written to the proper domains and not deleted. Can anyone tell me what changed in Firefox recently? Is this expected behavior, or a bug? If it's expected behavior, what can we do to allow users to opt out of personalized advertising?

How to restore cookies which have been deleted by mistake. I have accidently cleared all cookies from the cache. however, some of the important information from one of the softwares (Zerodha) was stored in the cache as cookies. Now the entire data is lost. How can it be recovered

Hello Is it Is it possible to have two separate installations of Firefox on the same PC. I would like one normal installation and one that would delete all cookies at shutdown. Thanks

Hi! I do not want more cookies than "necessary". So I reject, make settings etc. And I clean them automatically when closing Firefox, just in case. On some sites that I visit very often, this turns out very tedious and timeconsuming. How to allow only necessary cookies and not the rest? With Privacy & Security, Cookies and Site Data, Manage Exceptions, I can allow or block cookies from specific sites. What do I allow when I choose Allow? Only the ticked ones or all marketing and other stuff even when these are not preticked as default? Or will the choices made during this session be saved? In the case of my bank and a couple of others, I would like to save my choices to be able to enter it a little faster. But cleaning at closing Firefox also deletes that, I suppose? How to save my choices without saving all cookies?

Is there any way to see what kind of cookies have been saved? I can see the number of cookies for each site under Manage Data, but how to see the type of cookie?

Firefox 122.0.1 on Linux Mint

Best Eva

I don't know in which version exactly it happened but a few weeks earlier i was able to edit cookies like we can on all other browsers, but today suddenly i cannot.

I expected it to be a simple double-click and i can edit the cookie key name or value but it doesn't let me edit, it opens the detailed view about that cookie. I looked EVERYWHERE and could NOT find any way to edit the cookies for hours and this is really frustrating as a dev. This is important to troubleshoot many kinds of bugs when I am developing an app.

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

For several weeks now, whenever I close Firefox and shut down my iMac and open Gmail the next day, Gmail seems to forget which emails I have already read, and it marks many old emails as unread. Deleting the Google cache and cookies helps, but only temporarily. This problem doesn't seem to occur when using a different browser, such as Safari, or when using the built-in MacOS email client. Therefore, I'm thinking it's a buggy interaction between Firefox and Gmail. I didn't used to have this problem, so perhaps it's related to a Firefox update? Anyhow, I'm hoping someone can help. Thanks!

Just had firefox throw an error that I was running out of disk space for cookies. Open up the dialog, and was prompted that I had over 17,179,869,184GB of youtube cookies, and 5 GB of cookies for a site I was buying something from. Restarting firefox moved both down to a reasonable 304MB and the store to 207KB. I have never seen this one before.

Delete cookies and site data when Firefox is closed tab is checked so it should delete cookies, but it doesn't, and when I click on manage data there are still cookies etc. How can I make this automatically delete?

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. Can someone please explain why Facebook asks for username/password every single time Firefox is restarted? I do not use cookie-cleaning extensions. They also send a 'login attempt' email and phone notification every time.

Tried with and without Facebook Container. Not using other Container/multi-account related extensions. My settings:

Standard Tracking Protection (allow/block exceptions: none) "Do not track" signal: Always Delete cookies and site data when Firefox is closed: disabled (no exceptions) History - Firefox will: Remember History

Thank you

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.

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?

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.

With my previous browsers--such as Chrome and Brave--I could automatically get into key sites without signing in every time. I thought this was due to cookies that my login passcodes. In the case of Google, it is by far the most challenging. Despite having a gmail account since early 2003, and using Google regularly since the '90s, it persists in asking me lots of questions and texting codes, etc.

My situation with Firefox is not working smoothly as it was when I used it for many years about a decade ago. I've already imported such browser data from these sites.

Can you help? Otherwise, I'll move on to Safari again.

Thanks,

Eckhart

Please help fix this problem. As I was trying to access my account on Chewy.com, This message pops up: "The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies." I am hoping someone can tell me how to fix this.

I am receiving an error message that I don't know how to fix and it says "The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies."

I don't recall changing anything in settings.
