Pc freezes when I try to open Firefox

more options

No way to open Firefox. When I click to open the browser all the computer freezes during at least 10 minutes. Nothing can be done until browser agent user fail window appears.

I have tried to open at save mode and the same problem.

Any idea?

Finally I can open save mode and inhibit all extensions. Try to open again in normal mode and problem remains.

Using windows 10.

Al final restablecí el firefox con la opción de desisntalar y volvió a funcionar.
