This could entirely be me being tired, and thus a little stupid right now, but how exactly are you rebooting the system? If it’s by hitting the restart button, or powering off and back on, you may be having issues with something getting “stuck” in RAM, essentially. Try fully powering down the machine, disconnect the power cable (and battery if it’s a laptop), press and hold the power button for 30+ seconds, then hook everything back up and test again. That should be enough to drain any little bits of electricity stored in the system, thus fully clearing anything that might’ve been hanging around from RAM. Also, make sure the browsers are fully updated and no outdated extensions/plugins/etc.

You won’t even have to worry about fire then!
