I'm ignorant of a lot but, segregation of cookies by browser tab. If I log into Xsocialmedia in Tab 1, and go to news site in Tab 2 using Xsocialmedia plugin, it doesn't know that tab A logged in, or that it came from same browser. Basically, I want my tabs to be isolated and treated as completely separate, isolated browsing histories, caches, and cookies. ...This is my gmail tab. All that tab ever sees is gmail. This is my HN tab. All it ever sees in HN. Like I said, this isn't my field, but..

You can kind of do this with incognito mode. It would be a bit frustrating because once you close the tabs everything is lost. However I am not sure how different browsers "incognito mode" handle multiple tabs. I do like your idea though.

  Firefox has an experimental (opt-in) feature called "Containers" for this: https://testpilot.firefox.com/experiments/containers https://testpilot.firefox.com/experiments/containers You can create a container for each compartmentalized context (work, social media, whatever) and then create tabs assigned to diffent containers. They're visually distinguished as to which tab is "in" which container, but otherwise you can manipulate and mingle them freely with the rest of your tabs. Each container's persistent state is isolated from both the other containers and your default browsing context.

    oh wow that is awesome. I've not used firefox in years but something like that could be reason enough to give it another try.

  As a UI dev working in security, I can tell you that other security devs largely don't know what Incognito mode is or how the cookies are sandboxed inside/outside of Incognito mode. Some think cookies are segregated in each Incognito tab/window. Some don't know that the Incognito cookiejar is reused if you open another Incognito tab/window without first closing all other Incognito windows+tabs. This applies to LocalStorage as well.

I think you're talking about first party isolation, which I second. In the same way that the web should be secure by default, I think we should have privacy by default. > First party isolation means that all identifier sources and browser state are scoped (isolated) using the URL bar domain.
