Hi Since I installed Firefox 3 I have found that often when I either click on an email link or click on the firefox desktop icon it doesn't start. What I have found is that if I start Task Manager and look at processes it is already listed. By ending the process I am them able to start Firefox as usual. I presume this means that although I have previously closed Firefox it is not really properly shutting down, so when I try to start it later it refuses to open a second instance of itself. Any ideas thanks!
