Did you check your Privacy and history setting to make sure they aren't deleting cookies and history and tracking? I use Amazon on both Chrome and Firefox and don't have problem signing out and back with saved logins.

Hallo, thank you for your answer. But I want to delete all other cookies when closing the browser except amazon

Select 'Delete cookies and site data when Firefox is closed' then under 'manage permissions' copy and paste the amazon url and select 'allow'

When I enter and save cookie authority, these permissions have disappeared after firefox rebooted. How can this be?

You can specify which websites are always or never allowed to use cookies and site data. Type the exact address of the site you want to manage and then click Block, Allow for Session, or Allow.

Note the term exact above. To my knowledge Amazon sites use https URLs, not http.

You may also want to take a look at this extension. https://addons.mozilla.org/en-US/firefox/addon/cookie-autodelete/

the problem is, that firefox loses the exceptions after a reboot of firefox. 1.picture save exception 2.picture after reboot firefox

Hello Rolmei,

Would you give this a try please (if you haven't already) :

When you're on that site, click on the 'i' in a circle, next to the padlock at the left side of the address bar.

Then click on the little black arrow on the dropdown and then on "More Information", which will take you to "Page Info".

Click on the 'Permissions" tab and scroll down to "Set Cookies". Uncheck "Use Default" and check "Allow".

Then close and restart Firefox.

Does that work  ?

Hi Rolmei, turn off the feature to delete history when you close Firefox. Or if you want to use this feature for some kinds of history, go into the settings for the feature and make sure you are not removing either Cookies or Site Preferences. I don't know what they are called in your language, but here's an English screenshot.

According to the screenshots you posted you have 'Content Blocking' set to 'Custom' and you are automatically blocking Trackers and Cookies. It is better to keep the settings to 'Standard' and instead select 'Delete cookies and site data when Firefox is closed', then under 'Manage Permissions' copy and paste the url into the address bar and select 'Allow'.

The screenshot you posted above shows you created the exception for http: domains and not for https: domains like you should.
