Ephemeral Firefox as a Site-Specific Browser (3/3)

This article is a part 3/3 of a series describing how to setup an Ephemeral Firefox session as a Site-Specific Browser. The ultimate goal is to be able to have a self-destructing browsing session that can only access a single company's services, such as Google or Facebook.

After setting up the Site-Specific Ephemeral Firefox Browser, you can then blacklist services designated to your Site-Specific browser(s) (such as Google or Facebook) from your main browser. This significantly improves your ability to browse the internet without your activity being tracked by these companies -- leaving your sensitive data vulnerable to being stolen by hackers.

Ephemeral Firefox with Extensions (2/3)

I recently posted about how to create a sandboxed firefox profile to compartmentalize (and shred) your firefox browsing history in an Ephemeral Firefox session. But so far I've only covered how to create a simple vanilla firefox profile. What if you want your Ephemeral Firefox to include a few basic extensions?

This post will cover how to add extensions to your Ephemeral Firefox profile.

Using uBlock Origin to Whitelist

As some mega websites deploy APIs that are used nearly ubiquitously on most of the Internet's websites (I'm looking at you Facebook & Google), I've begun to compartmentalize my browsers to "jail" specific website usage to a single, sandboxed browser (profile). This is sometimes referred to as a Site-Specific Browser (SSB).

Besides making sure that your SSB is isolated in that it cannot access your regular browser's data (a configuration I plan to document in the future), it's essential to block all network traffic from/to your SSB and all websites, except a whitelist. Unfortunately, getting block-all-then-whitelist functionality in uBlock Origin was annoyingly not documented, so I decided to publish it.

If you want uBlock Origin to block all traffic, add the following line to the textbox in your "My filters" tab of uBlock's Dashboard.
