Hi,
I'm using the Cliqz browser for android, and if I try to login on a website that requires cookies while in a forget tab the login will not work.
I think the tab should accept cookies and remove them once the tab is closed. Google Chrome seems to do that.
I guess it's a limitation of using the Webview as the rendering engine, that it stores all cookies in the same spot. But I'm opening this issue so that you are aware of it.
