It appears there are multiple instances of Firefox running. I've been getting messages about Firefox not being able to restore pages. I don't want pages restored.

You can set fission.autostart = false on the about:config page to opt-out of this experiment and disable Fission.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
