Recently I over cleaned my computer with "Auslogics duplicate file finder program" and have since had problems activating some programs and accessing some websites; for example could not load Adobe Reader PDF files. Then I downloaded Foxit PDF Reader and then I was unfortunately stuck with Ask homepage. I tried to access "about: config" to disable Ask homepage but could not access the about config webpage. I have since reinstalled my homepage, but I would like to know how to access about:config webpage if I need to at some time in the future.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode 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).
