Afther a while my screen turns black. I can still switch between tabs but al the pages have turned black. The only way to use firefox again is to close the browser and restart it again. Even after it has been installed all over again. What is going on?!!

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