My guess as to what's new here is... nothing.

I'm thinking they will change the containers preference to default to on, and if the extension enabled the preference before maybe that's being removed. Otherwise the containers functionality in Firefox or the extensions in the extensions remain exactly as they were before.

So you still need the extension as it has the critical functionality of Ctrl-Shift-1 to open a new tab of the first container type.

My understanding is that the slowness comes from program code being removed from memory to free up space, forcing the system to constantly re-read it from disk. I still get the slowness without swap.

Great to hear he did his homework!

Last I looked into this, AIUI, the default in the US is "everything the employee does the employee owns" (damn you wedding photographers!).

So naturally, virtually every tech company contract will have a "work for hire" clause which says "never mind that, everything the employee does the company owns (on or off the clock, in the shower, whatever, it's all ours)".

California adds an extra exception, which is "whatever the employee does (on their own time and equipment) that is 'unrelated to the company's business' is still the employee's." While that may safeguard my oil painting hobby, I'd always be nervous about any programming (game or otherwise) if I work for a tech company...

Something like uMatrix can be used by the client, and Content Security Policy combined with Subresource Integrity can be used by the publisher.
