Hello, I have used Firefox for a few years but just recently I have run into this problem. I copy Twitter links and send them via email using Microsoft Outlook 2003. Within the last week or so the formatting will not stay the same as the source website as before. There are some Twitter links where the hyperlink will not even be clickable like before. I have used Internet Explorer to see if it was a Word or Outlook problem but using IE it works correctly like before. I have done a refresh of Firefox as well as removing it completely and reinstalling fresh. I have ruled out anything else but Firefox (I believe).
