While the Mozilla Foundation is trying to integrate the E10S multi-process architecture into Firefox which is a prerequisite for the browser's filtering, add-on developers seem to have just passed them by.
The new Firefox add-on, Priv8, adds sandboxed tabs to your browser, using the Firefox OS security model. It allows you to run tabs in a sandbox that separates data from the rest of the browser and other tabs. Please note that the add-on has been released as a PoC for now.
The add-on works by creating sandboxes and assigning domains to them. The sandbox works automatically, and does not introduce new features to the browser.
The first thing you need to do after installing the Priv8 add-on is to create one or more sandboxes. This is done by clicking on the extension icon in the main browser toolbar.
Click to create a new sandbox, and add a name and color. Once the sandbox is created, add the URL you want to connect to.
An interesting option is that you can create multiple sandboxes that use the same address. Sandboxes do not share data like cookies, and can be used to access as many accounts as you want on the same website, without any problems.
If you have two Gmail accounts, you can log in to both and use them simultaneously (although this can also be done without the add-on, if you know how).
You can tell sandboxes apart by their color. They appear in the active tab when you hover your mouse cursor over any inactive tab that is sandboxed.
Priv8 is a very interesting add-on, which highlights how powerful Firefox's APIs are for developing add-ons. It is, of course, too early to say whether the add-on protects or secures the browser and its data, but as long as it separates the data, it is on a very good track.
