Ever since upgrading to Firefox 4, I have had an issue entering text into boxes or fields on certain websites (blog comments, message boards, etc.). This happens on a number of different sites. Screenshot here: http://screencast.com/t/VSVLf408Qlsh The strange part is that if I copy-paste what I have typed into another program like Word or TextEdit, everything appears fine. If I compose a message in those other programs and paste into the text field on Firefox, it looks like the screenshot above. Any help would be appreciated. Thanks!
