Why is there nobody who gives a normal answer to this kind of often asked questions? How does one stop this kind of popups?

Such errors with internal Firefox files as the cause are usually caused by extensions that are misbehaving or (incompatible) extensions that are forced to load.

Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
