After upgrading from MS Office Professional 2007 to MS Office Home & Office 2010, I can't copy & paste text selections from the internet into MS Word 2010 documents. When I use MS Internet Explorer to browse the internet, I can copy & paste text selections into MS Word 2010 documents just fine. Prior to changing to MS Office 2010, there was no noticeable difference in copy & paste into MS Word 2007 with Firefox or MS Internet Explorer. Seems like MS Word 2010 is blocking the use of Firefox to copy & paste internet text selections into MS Word documents.
