Hi. Is there anyone having experienced similar phenomena?

1) Firefox stops showing Gmail correctly after a few days. Immediately after starting Firefox, I can log-in and open Gmail.com correctly. But after a few days keeping opening Gmail on Firefox, Gmail.com shows error messages regarding Cookie (please see the attached screenshot). If I do "Try clearing the startup cache" from trouble shooting information tab, Firefox shows Gmail correctly again, but after a few days the same issue happens again.

2) Fire fox cannot log-in on Outlook.live.com. As title says, I cannot log-in outlook live. Whenever I try to log-in from Outlook log-in page, Firefox shows log-in page again. This issue isn't resolved by inactivating "Enhanced tracking protection".

Both of them started to happen since the update around the end of 2023, I think. (On the other hand, Chrome works on both websites correctly)

If you have some information, it might help me. Thanks in advance.

Why do Cross Site tracking cookies show up after I shut down the browser and restart? I have my history set up to delete everything when I close the browser so I'm curious why cross site cookies are apparently allowed to exist/function, even after a restart?

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?

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?

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

Changing the cookiebanners.service.mode to 2 in Firefox for Android beta via about:config is not permanent. After some time / Smartphone reboot / shutting down Firefox the setting is changed back to the default setting. -> how can I persist that setting?

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.

I'm looking for a simple extension. A one-click extension that would enable me to delete cookies at any time during a firefox browser session. I would like to exclude some cookies from deletion, so I'd like a whitelist option.

Has anyone come across an extension like this?

thanks for your consideration

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.
