I discovered that overnight my Norton 2010 updated to now include IPS 2.0, and thank you for your work in this regard.
However, this update removed numerous buttons I had installed on my Google Toolbar, and it removed several Firefox Add-ons, calling these incompatible with Firefox 3.6.
What gives? All of these buttons and add-ons were working just fine with Firefox prior to the appearance of IPS 2.0.
Thank you for your reply.
