I use the default setting that all cookies be deleted when I shut down Firefox, and then hand-input dozens of exceptions. The Firefox update on November 11, 2025 -- and I didn't even click on install, I only downloaded it, then hesitated, being afraid that it costs me again hours to re-create what the update destroys, but Firefox went from download to automatic installation -- meant that Firefox wiped all cookie exceptions (list of cookies that are not deleted when I shut down Firefox). These exceptions are hours of work, and, additionally, every bank etc. now requires me to sign in and go through many-factor authentication anew. -- How do I restore the long list of cookie exceptions that the Firefox update just deleted?

+ The same update wiped all bookmark icons. My three dozen bookmarks in the bookmark toolbar now come with the 'globe' symbol rather than the bookmark-specific symbol, so I can't tell which bookmark is which. How do I restore the bookmark symbols that the Firefox update just destroyed?

Unsure if this is correct category... Years ago when Firefox was in it's infancy - Firefox settings used to allow much more power/control over cookies & how you deleted them. You could actually display & select individually ones you wanted to delete. Now Firefox has it's own Interface 'utility' and only allows you to delete 'groups' of cookies based on their App name. I was looking for the location / name of the dataset which is used to store cookies - so I could delete them more finely. Or is this in some sort of special format which is ONLY accessible thru Settings. I see MANY Cookie add-ons, mostly dealing with auto-responding to cookie prompts. Actually as of this writing - I am trying one of these.

I am having the same problem as this fixed one, a year later: https://support.mozilla.org/en-US/questions/1468647 As soon as I try to connect to an account via Google, or go to Gmail/Docs/Drive/Classroom, I'm always taken to a “Clear cache and delete cookies” page. So I followed the instructions on the page, deleted all my data and saved cookies from Firefox and even tried to reinstall Firefox completely, but nothing changed, I'm always redirected to this page. Logging in when in incognito mode works fine though.

Firefox version 144.0.2 MacOS Ventura 13.0 Language: French (FR)

Hi! I am using MacOS Firefox and configured:

Delete cookies and site data when Firefox closes.

However I could not find this option in Firefox for IOS or iPadOS and therefore unwilling to use it on these platforms. I find it unconvenient manually deleting those data before closing and I hate foreign software installed on my devices.

Is there any settings I have missed?

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

I recently noticed that my Microsoft account remains active after I sign out if I press the back button. All my personal and account information is still displayed, indicating that the account is still signed in. I even tried clearing all browsing data and history, but that didn't resolve the issue. This doesn't happen with my Gmail account, nor when I access my Microsoft account using Edge or Chrome.

I understand that closing the browser likely signs me out, but I have no way to confirm that unless I check for active devices in my account settings. Can you explain why this timeout issue occurs? It seems odd, especially since Mozilla prioritizes security and privacy.

When ever I shut down browser clears history and most importantly signs me out of all my accounts making me to sign in for every account I have. I need to stay signed in all my accounts.

When I try to log on to a particular web page using my password, I get an error page. When I do so using the Private browse function it works. Following is the error I get: {

 "callId": "019a1701de257ed0a722da6257f2896e",
 "errorCode": 403005,
 "errorDetails": "Unauthorized user",
 "errorMessage": "Unauthorized user",
 "apiVersion": 2,
 "statusCode": 403,
 "statusReason": "Forbidden",
 "time": "2025-10-24T16:16:29.758Z"

}

Does anyone have any great ideas??

This may seem like an old problem, but I seem unable to fix it. I have a web site for which I updated the home page. But when I tried to have Firefox load the home page from the web site to be sure it looks OK, Firefox loads only the local copy from past loads of the home page and I do not see the updated page at all. I have tried clearing the cache, but that does not fix the problem. It seems that something has changed as this method, if I recall correctly, used to fix the problem. I am sure the fix is simple, but it has eluded me. Can anyone share the fix for this? I currently use Windows 10.

ブラウザゲームサイトUnityroomなどでゲームを遊んでいると、Cookieの容量が10ギガバイトを超えることがよくあります。 どうやら10ギガバイト以上のcookieをFirefoxでは保存できないようです。 FirefoxでのCookieの容量を10ギガバイト以上にしたり、ページごとに個別に管理できるようにしてほしいです。
