I have 'Clear cookies and site data every time you close Firefox' enabled. In the list of exceptions, I have many website listed, most of which work (such as 'crucnyroll.com'), however I am having issues with certain sites, in this case 'bandcamp.com' and 'the-trackr.com'. When closing and reopening Firefox, the rest of my Exceptions retain Cookies and Site data fine, but these two websites specifically seem to ignore the rule. I have tried disabling all my extensions, changing settings around, and reading through the 'about:config' page but couldn't find anything which would resolve this issue. I have things setup this way to prevent tracking from random forums, blog posts and the kind, but can only seem to resolve this issue by re-enabling cookies for all websites. Any and all help is appreciated, and thank you in advance.

Hi, I am on Firefox 159.0 and I am having troubles with cookies being cleared on sites that I have allowed under Privacy and Security > Browsing data > Managing exceptions and Clear cookies and site data every time you close Firefox. I have GitHub ("https://github.com") allowed in the exceptions and if I restart Firefox after signing in, then I am logged out of GitHub. Is there any way to fix this?

I thought this was for the active site, but, from my experience, after being logged out of other sites, does it actually clear for all tabs? Why do they make this so ambiguous?

Is there a simple way to get this done, for the active site only, without adding an extension?

Is this for the active site only? It's a bit ambiguous. When i use it, is it just coincidental that i have to re-log into other sites, as well as Mozilla?

Is there a simple way to do this without adding an extension?

Where is the access to cookies in the Firefox settings. I need to delete the cookies for a particular site in order to update my account documentation on that site.

Hi. I tried to log in to my new bank website today and it's asking me, each and every time, to fill out the pass code it has sent to my email. I went in to settings on Firefox and added the website as an exception so that the cookies for that website aren't deleted and, lo and behold, when I try to log in, again the bank website is challenging it as a new device and sending me a one-time code! So, for some reason, it hasn't saved, or at least not registered, the fact that this should be a safe website where cookies are saved!

I'm trying to copy and paste the list of exceptions to show you but it's not allowing me to copy and paste them.

Can you please clarify how I can add these cookies so that the website doesn't see my desktop as a new computer each and every time I log in to my account on my desktop?

Certain web sites want to identify my computer ass a trusted device but the cookie that does this is erased every time I shut down Firefox. Is there a way to save a cookie? For these 3 sites only.

My manage exceptions list is now being cleared out and clearing out all the cookies and site data with it when I close my browser with the "Clear cookies and site data every time you close Firefox" checked off.

It should only be clearing out cookies and site data for everything outside of the allowed things in the managed list.

I think Firefox’s two separate settings for website data are somewhat confusing and redundant; “Custom History” under “History” involves and duplicates the functions of “Browsing Data,” and “Browsing Data”’s “Clear cookies and site data when Firefox closes” I want to simply achieve allowing cookies to be saved only for a few specific websites and clearing all other data on exit. Edge can turn off “allow sites to save and read cookie data” and directly add exceptions, and it also has only one option for choosing what data to clear on each close, which is more concise and clear enough. If possible, I hope the technical staff can make changes to this, preferably by referring to Edge’s conception for this part.

Please change my settings back to where important cookies aren't deleted! Now, every time I go to a regular trusted website (i.e. - to pay a bill) I have to register all over again! How do I change it?

For the last several weeks, one of my computers when it updated to the new settings menu (version 156ish?), it has lost the ability to maintain some of the synced profile settings. For example, I have a couple websites that I list in the exceptions to not have Firefox clear the cookies, and I additionally have the clear cookies and site data check box enabled so that every other website I visit clears upon exiting. This is the setting combination I have utilized for years to keep the cookies from only 2 websites and clear out everything else.

On one of my computers, I'm able to add the exception, and as long as I do not close Firefox, the website exception settings stick. However, as soon as I exit Firefox, and open it back up, the settings clear themselves again, and I have to manually enter the exceptions again. This is very frustrating because one of the sites that I keep the cookies on the exception list has multiple different logins saved so that I don't have to manually re-login to every time I open Firefox.

I have attempted a refresh, and that did not fix the problem. I have fully uninstalled Firefox, manually deleted the %APPDATA%\Mozilla\ folder contents, reinstalled foxfire and this too does not fix the problem.

The weirdest part of this whole issue is my laptop, does not have this problem and the exceptions are sticking so I know that this setting combo works. Additionally, I have tried unchecking the clear cookies and site data box and this too is not allowing the exceptions to stick.

I have also tried re-syncing my account to pull the settings from my laptop and this too is not working.

This experience is on Firefox 157.0.1 (64-bit), Windows 11 Pro 26H2

Thanks for your time and please advise as to how to fix.
