You can verify Fission is enabled by looking for “[F] ” in the page title tooltip when you mouse over a tab.When Fission is enabled, you can open a non-Fission window using the “File > New Non-Fission Window” menu item. This is handy for testing whether a bug is specific to Fission or not.To disable Fission, reset the “fission. autostart” pref to “false” and restart Nightly.
