I use Strict Tracking Protection, Facebook Container and Multi-Account Container and I am beginning to think it’s overkill. Doesn’t Strict mode block third-party cookies anyway? I also clear cookies on exit. Containers allow us to login to the same site with different identities, so I am assuming it containerises first-party cookies too, but I wouldn’t need that. Also, doesn’t Multi-Account Container replace Facebook Container if you create a separate container for Facebook?


“Facebook Container” seems redundant if you already use Multi-Account Containers and set it up accordingly, yes. Other than that it doesn’t sound over-the top at all and a reasonable configuration.
Almost, but not entirely. For that you need First-party Isolation (
privacy.firstparty.isolatepref: https://bugzilla.mozilla.org/show_bug.cgi?id=1330467),It does do that - if it didn’t, there wouldn’t be any “multi-account” to it.
With a profile like that you might also find Konform Browser relevant to your interests with more private defaults and convenient toggling of modes and features. https://konform-browser.codeberg.page/
It comes with a debloated version of Multi-Account Containers, which can also be installed as a normal addon into other Firefox builds: https://codeberg.org/konsortium/multi-account-containers-lite
Unless I misunderstand this, the problem with Multi-Account Containers is that sites sharing the same container can read each other’s cookies probably because MAC is actually designed for multi-account scenarios rather than to isolate each site. I wish there was a way to containerise each site by default without breaking the web.
Looks good but I would miss new Firefox features and the stricter the restrictions the more friction. I used NoScript for a while in the past and it was a nightmare.
