I share the same goals; thanks for the succinct description.
Discussion upthread made me interested to see whether I can route temporary containers through tor, to make this protection stronger — see https://news.ycombinator.com/item?id=24853320
It's not super high on my list of priorities though, probably won't get to it for a month or two.
Oh, that'd be very neat if it made separate container tabs look like different tor sessions. Very clever! I suppose there's little short of that which would stand a real chance of working...
Everything else opens links in a new container with the hope to make it as close as possible to looking like a different person clicked that link. I know it won't work that well since the IP doesn't change nor the user-agent, but at least it helps with the most lazy tracking.
