I have a laptop that I installed Ubuntu 6.01 and upgraded it to 6.06. After I updated Ubuntu I was unable to get Firefox to open. When I click on it acts like it is going to run but I get a message that tells me that Firefox is already running but not responding. I have rebooted the computer several time but it changes nothing. I have gone it and killed the program and tried to restart Firefox but I get the same message. Would it be easer to install a new Firefox program and remove the old one or is there a simple way to get the current Firefox to work. I am new to Ubuntu so keep it as simple as possible.
