I wish every domain could automatically be opened in an individual container. I don't even need to know about them.

I use this in combination with "normal" containers and it works a treat

[SAI_Peregrinus]

Same. The mix is IMO the best way to get privacy while keeping usability. It obsoletes things like cookie auto-delete.

There is some annoying UI lag when opening a new tab though, as it takes a fraction of a second to swap from default to a new temporary container.

I use this plus Containerise, but with recent updates to Temporary Containers, I don't think I need Containerise any more.

[Yhippa]

Just curious: is there significant overhead to running each domain in it's own container?

That's an existing Firefox feature called First Party Isolation. Here's a plugin that toggles it:

It sometimes (rarely) breaks payment processors but otherwise works fine

There's also the privacy.firstparty.isolate in about:config which isolates each site.

That would break a lot of stuff, though. And then I don't just mean "bad" tracking, but normal auth flows etc

[katet]

You're quite right - I have some trouble with "modal" popup windows and the Atlassian Single Sign On in particular with the temporary extensions tab. But I eventually figured out to copy and paste those URLs and manually whitelist them to a specific container tab

I wouldn't recommend it for family or friends, but I'm happy with the trade off

There is a temp container extension that does exactly this.
