Firefox Community Forum

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.

Think I've asked before, but I'm still having the same issue: in my Firefox (desktop, Windows 11), in the storage\default folder in my profile, there are, today, 5442 files! 416 folders appear here, with each one containing one or more folders ("Is", "idb", and/or "cache"), which, in turn, contain several files each, and a ".metadata-v2" file. The oldest of the 416 folders in 9/16/25. What is all this? I regularly delete all cookies over 30 days old in Manage Data.

I am following all the online instructions I can find to turn off private browsing on Firefox - in Privacy and Security by clicking on 'Remember History' for example, and also restarting laptop - but it is not working and I must constantly log back into all my accounts and websites, including my e-mail account. I need assistance with specific and exact instructions how to remove private browsing and explanation why not working what I have already tried. Thank-you for your assistance.

I've been trying to get Firefox to save cookies for a few desired websites (bank, investment accounts website, Sync... and of course Firefox/Mozilla itself) so I don't have to constantly use the 2FAs for those accounts. Firefox refuses to keep me logged in to my Mozilla/Firefox account. Every few hours -- or at the very least, after a machine shut-down -- I have to re-login if I re-start Firefox.

I do not use the Firefox Password Manager; it's unchecked in Settings. Nor do I use the Autofill options in Settings. I use the Bitwarden Extension (set to Never for locking/logout -- because this is a home computer) for Firefox to log in to my sites, with a separate authenticator app, Authy.

The Firefox Privacy & Security Settings for tracking cookie blocking are the Standard ones; I haven't done anything to customize them. Further down on that page, I've tried leaving the box blank for clearing cookies on exit. I've tried checking the box and setting up exceptions for those few sites I'd like to login to without having to go through the 2FA rigamarole. I've done multiple Refreshes, clearing of History, uninstall/reinstalls including deletion of every Firefox profile and anything hinting at a connection to Mozilla or Firefox in all Users on the computer, including all the AppData folders. A few days ago, I even deleted the Mozilla/Firefox account and set up a new one with a different email address.

Nothing seems to work. Most recently, Firefox still had all the relevant cookies after the computer was shut down overnight, but an hour into my day's work, after closing Firefox and re-opening it a short while later, all the cookies are gone once again!

None of this was an issue about three months ago. I could save the desired cookies, get rid of other ones, use private browsing, etc. etc., with basically the same set-up and with the Mozilla/Firefox account I had had for years. Now, I've had to delete that account in an apparently vain effort to try to clear out anything "Mozilla" from this computer -- and it didn't work anyhow.

(I posted about this same issue a week or so ago, but didn't receive any responses and have now deleted that Mozilla/Firefox account -- see above -- so this message is an update.)

I've recently sync'd my PC bookmarks etc to my android tablet and since then web sites that previously remembered me now keeping asking me to log in. BBC news, FaceBook are examples.

Hello, I have been aware of this issue for about a month now. I have, for example, added 3 sites to my "Block" list under "Manage Exceptions" in "Cookies and Site Data". They are not only repeatedly disappearing from the exceptions list without my input (which I suppose is the bigger issue), but even when they are present, the websites still end up storing cookies and site data for the session. These sites are Wikipedia, Bing, and DuckDuckGo.

In addition, I've also added a finance website to the "Allow" list, as the browser is set to delete cookies on quit. This website has also repeatedly disappeared from the exceptions list without my input.

My version of Firefox updates regularly via the Linux Update manager. I am also wondering if the "Forget about this site" option in the History menu generates this (at least to me) unexpected behaviour. I would expect that using the "Forget about this site" option would delete site data, cookies, and history, but not remove it from my Cookies exception list...

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",

 "apiVersion": 2,
 "statusCode": 403,
 "statusReason": "Forbidden",

}

Does anyone have any great ideas??
