I am getting an error message that "A copy of Firefox is already open. Only one copy of Firefox can be open at a time" and I don't have any copy open.
I am getting an error message that "A copy of Firefox is already open. Only one copy of Firefox can be open at a time" and I don't have any copy open. How do I correct this problem? I really like firefox because it runs many technical programs on the web that do not work with safari. I have FireFox version 32.0.1 installed on my MacPro PowerBook OS X 10.7.5. My activity monitor does not show any FireFox activity, so do not know what it is seeing

I get this problem all the time. It is easy to fix. This usually happens when you have played a movie in Firefox and when you close, Firefox process is still alive.
Just go into Task Manager, under processes and kill Firefox.
Does the Mac OSX 10.7.5 operating system have a Task Manager application?
From what I have been reading from other posts on this forum, the issue may be caused by the clear history settings. It was suppose to have been fixed in v30.
Type about:preferences in the address bar and press Enter.
Select Privacy.
The button next to History, select Use Custom Settings.
At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.

This worked, I used the method described in this link http://forums.mozillazine.org/viewtopic.php?t=365156, and opened the Mozilla profile screen with the terminal on my mac, using the language given in the links. Then I duplicated my original profile to save the bookmarks, etc. Put them in a folder listed Duplicate profile with the date. With the open profile screen, I deleted my original profile, created new profile folder and then a new profile. Note that profile cannot be created in the system library, it must be created on the disc, because the library will not allow writing into it. After I created my new profile folder, I dragged all my old information into it, and it worked. Firefox closed and the error disappeared. You must be VERY careful to make sure Firefox is closed anytime you are doing anything with the profile folders. I think that is what caused my original problem.

These add-ons can be a great help by backing up and restoring Firefox
FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.
