I noticed that my mother's laptop was running Firefox 3.6 still, and offered to update. I downloaded 8.0, and ran the install. Had no issues with the install, no errors, nothing. I told it to run after the install finished, and it never came up. I tried the icon, still nothing. I downloaded Firefox 7.0, and installed it, figuring there might have been an issue with 8.0, since it just came out, nd tried it, same result. I rebooted the system, and tried again, still nothing happens, just the little hourglass for a moment, and then.. nothing. There is nothing in the task manager, no process for firefox. I tried running the profile manager and the plain program from the run under the start menu of windows with antivirus turned off, and got nothing there either. I'm running windows XP Pro ::edit:: I was able to re-instal 3.6.24 back over top, and it works, but I would like to update it for her still, if it can be done.
