Google Container for Firefox

My understanding is they kick in automatically. So even if you're on someblog.com, the FB 'Like' buttons won't be tracking your behavior, nor will Google analytics and Google Doubleclick.

Last time I checked, the site-specific container extensions (Facebook and Google) had a "don't open anything except the target site in the container" feature that appeared to be missing from the multi-account containers extension.

I agree that the best solution would be to add that functionality to the base extension rather than create a specific extension for every site people might want to block.

It's not quite the same functionality. If you open Google in a regular container and then click a link that goes to a different site, it will load the new site in the same container. The Google container would open the new site in a different container.

The irony. You are asking if there is an extension that blocks the browsers company from tracking you. I don’t think they would allow it on their web store.

No, Chrome doesn't have equivalent APIs to those Firefox offers here.
