Which is still missing a key feature - I want to be able to independently clear history/cookies on a per container basis.

Give me a 'garbage' container for general browsing that is flushed by default, but bespoke Netflix/Github/etc containers that retain cookies forever.

I've been using the Temporary Containers addon for this and it's been good so far: https://addons.mozilla.org/en-US/firefox/addon/temporary-con...

I don't understand why you can't quickly set this up?

To independently clear on a container-basis, why not just delete the container? Stop treating your containers like pets and start treating them like livestock.

Cookie AutoDelete will do the trick. It has per-container deletion rules.

isn't this already achievable with containers and also private browsing?

At least for cookies, Cookie Manager extension can do exactly that.

I think you can kind of do this now? The Temporary Containers plugin will create throwaway containers but you can also create permanent site-specific containers.

My fav feature is the Temporary Containers extension. Using that, I never run out of my quota of "free" articles on news sites that keep count.

... that is a brilliant use case for that.

Isn't this included in FF by default? At least I use it and don't see it in my extensions. Only thing I'm missing is automatic containers for certain domains (as it works with FB).

Multi-Account Containers[1] is a Firefox add-on that lets you separate your work, shopping, or personal browsing without having to clear your history, log in and out, or use multiple browsers. It's an improved version of the Containers feature built into Firefox Nightly and available to advanced users by setting certain preferences (see below).

FF supports containers used by that extension natively; I think the extension basically adds some UI around it.

You can (one-time) set up domains to always load in certain containers, that works well for me.

I’m confused by this as well. It seems like a feature I would like to use without an add-on but they don’t seem to make it easy to find.

So much this! I have multiple business entities that all use separate accounts on many different services. I use the Window Titler extension and different windows for each business entity. This is the only way I can keep them all straight and it makes switching roles so easy. I just wish Firefox allowed me to Move Tab to a specific already opened window - seems like such a simple addition.

Unfortunately one of the services doesn't function properly on Firefox and so I have a constant nightmare of sign-in / sign-out / disable automatic sign-in (that somehow get auto checked) on de-googled Chrome.

I use the Window Titler extension to give my windows names and the Tab Mover extension to move tabs between windows.

This way I name windows after a project and as needed I'll move a tab there if I happen to open it in the wrong window.

As a tab hoarder this has really enhanced my organization and ability to find things again.

Also nice to seperate social media/shopping/banking/... I'm not 100% sure it completely prevents social media company X from knowing which items you searched for or bought from Y, but at least it should be a lot harder.

Also traditionally NoScript though I believe there are equivalents now for Chrome too?

Brilliant, I've been struggling with this, and this solution didn't occur to me!
