firefox locked on a website on March 23 and stopped functioning altogether as a server PLUS I can no longer shut off my MAC except manually and then manually turn it on with out the Mac start up sequence. I cannot download updates as Firefox cancels my attempts as it cancels my effort to shut down normally ...it is a great disappointment and a disaster to this non techie who was advised to download Firefox by other more savvy users...HELP A new Mac owner
