\\Firefox76.0.1

does the job well , disconnecting is a bit tricky. i need to manually disconnect after browser restart as i need the proxy only two or three times a day for few minutes. and if i forget to disconnect it after use, i feel guilty of using resources unnecessarily. developer kindly create an option in settings to disconnect or not to disconnect after browser restart and the add-on will shine.
thank you for the add-on.
