Hi there having a problem with Firefox, it shows its open in the dock but i cant close it . Even when I try force quit nothing will happen. Any ideas on what I can do. Appreciate any help. Thanks
The OP stated Firefox wasn't in the Activity Monitor. If it doesn't show up under My Processes, they may wish to set the dropbox menu to All Processes.
I would suggest upgrading to the latest version of Firefox and then I would run a check of the disk permissions and, if necessary, repair them. Go to Applications>>Utilities>>Disk Utility.
I fixed it by going to Activity Monitor and ending the Dock application. Usually it will restart but if it doesnt, just goto /System/Library/CoreServices and click on Dock to start it back up again.
