This is so useful for web developers, makes me glad I'm using Firefox. Unlike Chrome's private browsing, every time you click that icon, the new tab has a brand new "cookie jar" so you can be logged into any app with multiple accounts on multiple tabs making debugging a breeze. Also for normal multi-account use.

Ok

Awesome use of Firefox`s containers. If you want to use two logins on one site or dont trust a site, this feature makes Firefox`s container isolation very easy to use!

This fixes the official Multi-Account container extension's main weakness.

You can use this extension's "Isolation" setting so than when you click on a result in a search engine, for example, it automatically loads the new site in a temporary container instead of loading in the search engine's container.

Now Google can't follow you to the sites you open through its search results.

this add on has changed my life, love it. it needs way more hype!!!

Great extension. This extension is the reason why Firefox is unique to all other browser compared to privacy.
