When you start Firefox, you may receive a message that Firefox is already running. This can be caused by one of two things: 1) Clicking the "WWW" Firefox icon multiple times - Firefox may take a minute to load on slower machines, and clicking it repeatedly will cause this error. 2) Logging out before quitting Firefox. To remove the lock file, do the following: 1) Ensure that you are not actually running Firefox on your current machine or any other Athena workstation. If so, quit Firefox. 2) Type the following command: athena% find $HOME/.mozilla/firefox -name lock | xargs rm 3) Restart Firefox by typing "firefox" at the athena% prompt or clicking the icon in the panel at the bottom of your screen. Please click the icon only ONCE and then wait for Firefox to start. Last Updated: $Date: 2007/11/14 18:29:19 $
