Significantly easier to use than Temporary Containers, you just browse like normal and websites suddenly stop remembering you, without needing to go through a long drawn out process to handle being able to stay logged into particular sites.

Only real pain point is that you can't do a few things you can do with Temporary Containers + Multi-Account Containers, like have one website have multiple persistent containers (like keeping your various Gmail accounts separate, but still being able to right click a shortcut and log into the appropriate account). Or the ability to permit certain sites to share info temporarily, such as for more complicated sign in processes like OAuth.

But just being able to browse in relative privacy without needng to go through fifteen extra steps just to log into a website is just so nice that I'm kind of putting off disabling the add-on to manage all that other stuff. I'd rather just use Thunderbird than deal with Temporary Container's nonsense again, this extension is just that good.
