I've just upgraded from FF 2.0.0.20 to 3.6.28 (using KernelEx 4.5.2). If I click on a link in Outlook Express or double-click on an HTML file and FF is not running, FF 3.6.28 starts up and displays the link or file correctly. However, if FF 3.6.28 is already running nothing happens. Is there a solution?
