Hi, all.
In view of the many problems people have been having with toolbars and extensions recently, may I suggest that if you turn off your systems at night, that you make a habit of running Live Update manually when you log on next day.
That way, you are sure of being fully patched BEFORE you update your browsers, and that there's a better chance that everything will work as it should.
Rebooting fixes a lot of issues and if you're a Windows 8 user, remember that Norton requires a complete shut down, to properly update.
