After I got a new computer, the Browser Firefox sometimes can not be startet. After a restart of the system, I sometimes have the opportunita to restore Firefox, and then the program starts.

After a few times using Firefox, suddenly it will not start again.

Sometimes I get also an error message: There is a problem while starting of C:\ProgramData\BrowsingSecure\MUNKYCQS32.dll This module is not found. After searging, I found out, that this module is not available. Only the module MUNKYCQS64 is available.

How can I repair the Browser Firefox?
