After installing or uninstalling a program or after installing a Windows update requiring a reboot, I lose Firefox and have to reboot a second time.
Am running VistaSP2 on a Dell E520 with a Kaspersky based AV program. Ever since I installed the latest version of Firefox I find that when I install or uninstall a new app (e.g. Adobe Acrobat X Pro, Skype, Windows Messenger, etc.) or when I install an update from any source that requires a reboot, I find that Firefox will not start. Even the UAC confirmation window will not open. I have to perform a second reboot to be able to open Firefox. I have uninstalled Firefox and reinstalled it and it does not help.
