Suggest enabling Firefox Fission Site Isolation on Browsers category

[RiQuY]

With the latest update (94.0 stable) Firefox added an option to enable Fission Site Isolation to avoid side-channel attacks.
This option can be enabled in about:config and it appears as fission.autostart. This option is disabled by default.

Please add this suggestion to the PrivacyGuides website, below the section "How to disable WebRTC in Firefox?" in the "Browsers" category.

This option is disabled by default.

it is being incrementally rolled out tho, so you can expect it to be enabled by default for everyone, at some point.

In two releases if no bad things come out.

We're not suggesting this, it will be rolled out very soon and already has been on browsers with experiments (non arkenfox users).
