Using Process Explorer you can see that firefox.exe is running even though it appeared to exit and all of the windows are gone. The only way to run Firefox again without rebotting is to kill this hidden, woindowless process using Process Explorer or Task Manager. Reproducible: Always Steps to Reproduce: 1. Run Firefox 2. Exit Firefox 3. Try to run firefox again; it doesen't (or) use task manager or process explorer to see that firefox.exe is still running Actual Results: I kill the firefox.exe process, then I can run firefox again. Expected Results: Should have exited completely, and freed up all resources it was using. I uuse Firefox on many W2K Workstation and Server machines. They are all up to date on the Windows Update patches. This problem only happens on one of them (my primary home machine). I tried completely uninstalling, then reinstalling, to no avail. It's a Dell SC420.
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b2) Gecko/20050309 Firefox/1.0+ I have a simular problem, although in my case, it isn't anytime I try it exit, it is only after visiting this site that uses java: http://sazraceforthecure.kintera.org/faf/home/default.asp?ievent=92540 Is it possible that your default homepage uses flash, java, or some other plugin?
