Windows 10 1809. Upgraded to new FF and not working at all. I turn off all proccess from task manager and then it open but in white screen as in picture. Option button no work.Nothing works.Only help,about troubleshoot work. Reset doesnt help. Clean 100% fresh install doesnt work. (deleted everything has to do with mozilla from files and registry.) Even with restart. SoS!!!! dont ask me stupid questions because when installing 58 version works fine till auto update that mess things up again.

FYI 66 is beta so unless you're installing for testing purpose you should use the 65.0.2 public release.

Hi eyuri, what was the latest version of Firefox that ran normally for you?

For this --

I turn off all proccess from task manager and then it open but in white screen as in picture.

-- do you mean you terminated all the firefox.exe processes, then on your next startup, Firefox got to the blank tab? Or were you terminating some other processes?

Is it possible to test with your security software (Qihoo) disabled from blocking/filtering Firefox to see whether that makes any difference?
