I can't access internet explorer anymore, Firefox, Chrome, Opera and Safari are not able to use the plugin and see the cam on the browser, so the motion detection feature is impossible to use. 

You should update the firmware in order to not use the NPAPI plugin anymore. Shall I throw my cam to the trash and buy a new one? is that what we supposed to do?

I'm about to purchase a new cam, and guess wich company I am avoiding...

Just a little adive, don't play with the Planned obsolescence because the customers get angry and move to another trademarks.
