It's good, but somehow it manages to circumvent the Container separation which is scary; and if you enable it on Private Windows, your Keepa user (as with Containers) is still logged in even on the Private Window, which is even MORE scary.

This means that Keepa (and associates) can track you even when using Containers and Private browsing.

I disabled it for Private browsing, but I'm thinking of disabling it also on normal browsing.
