Version: 5.4.90 rc1 (missing in version selection) Akregator seems to remember cookies only for the current tab. When you open a site for the first time you get the whole "we are using cookies blah blah" thanks to EU law. This happens on every new tab I open in Akregator. Example: Read something by opening a new tab e.g. https://www.extremetech.com/ you see the quite intrusive cookie message. Close the tab open it again and you get the same cookie message again even when you closed it before. I created a new user and still have this problem.
Created attachment 105120 [details] e.g. Cookie message which appears every time
https://phabricator.kde.org/D17638 might have fixed it, please text with the netx major release (akregator 5.11) and reopen if still present.
