Today earlier it was fine but now it will not open. The computer has been restarted a few times and forced to shut down. I have firefox that says it is running on the task manager growing in memory but no web page. I have ended the process a few times and it terminates it on task manager. Then it says firefox plugin stopped working and checking for something so I hit cancel. Twice when I did this it asked me to start firefox in safe mode. I said ok safe mode and it came up but immediately hosed up. The second time I just said restart firefox. So the task manager says it is running but there is nothing on the screen, no window nothing. I have windows vista as well. This is a good browser but what is up? I am not too good with computers so no super technical words when giving me help just tell me what to do. Thanks

By the way when I say the computer shut down, I mean I shut it down thinking it might solve the firefox not opening problem.

Please tell us about your system. Type of computer, Firefox ver . . . .

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).

Try to start Firefox with the about:blank page by creating a copy of the current Firefox desktop shortcut and add a space and -url "about:blank" to the target field.
