Firefox Community Forum

Hi,

I am in the process of migrating between systems. I have my desktop with Firefox, I use some multi account containers, I clear cache and cookies on browser close and I have some exceptions to not clear cookies, as I want to stay logged into my accounts. It worked fine on my desktop.

Now, I tried to do the same for my laptop. I turned in account sync and add on sync, my browser settings and containers are indeed synced. But the exceptions are not synced, so I tried setting an exception for some of the sites like my desktop, logged in, closed browser, and I am not logged in anymore. Nevertheless, the exceptions are still remembered.

Some details:

   On my PC, The exceptions are both in the Browsing Data section and in the History exceptions. So I tried setting the exceptions to both on my laptop too, still no success.

   On my desktop (where it works), I don't use the "Always use private browsing mode" option, and on History->settings "Cookies and site data" are checked, and "Site settings" is not checked.

Can anyone please help me troubleshoot this? I really don't think it should be that hard, maybe as Firefox updated it became bugged or something?

Thanks in advance.

Every time I close Firefox, I lose cookies for banking, financial and news access requiring me to go through a lot of effort. re-establishing cookies with painful waste of time, I am hoping a change to the config files will override user settings that delete everything when firefox closes.

Failing that, can you designate which cookies are permanent anywhere in your application?

Since FF 09/15/26 update manage cookies and data sites no longer will delete items. I click the 'save changes'. and that's it. All the cookies and data are still there. Hopefully a fix will be soon?

In the past couple of weeks (say Sept 2026), Firefox has started signing me out of everything when it closes or updates even though 'clear browsing data' is UNchecked. What else can I do to stop this?

It seems the default for allowing sites to store data locally is backwards (for privacy).

You should be able to set the DEFAULT to "Allow all sites to store data locally FOR THE SESSION ONLY," and then type in the sites that you would like to allow to store data locally for more than one session (or block entirely).

Is there a way to do this? There are not many sites I would like to allow permanent local data storage, so it wouldn't be such a terrible chore to type in their URLs. The opposite is true for sites I would want to allow ONLY FOR the one SESSION - that is a HUGE chore. This appears to be a privacy & security oversight - can you fix this?
