Please make sure to finish all your posts before this time. The downtime should only last for a few minutes.
In 12 I run it with cookies and scripting turned off globally. Then I was able to add preference buttons to the toolbar to turn each on/off and also see their status. That way I could leave them turned off globally for privacy/security/performance reasons (and add the sites I visit regularly to the whitelists) but still quickly enable them for new sites.
I'd like these preference buttons that could be added to the toolbar back.
