I have been running Firefox ver. 22 32bit in Ubuntu 12.04 LTS 64-bit with no problems.
I don't run Firefox from the repositories. I downloaded the
.tar.bz2 file and extracted it in my home directory, then created a desktop shortcut. Ubuntu 12.04 LTS 64-bit requires
ia32-libs for the 32-bit Firefox to start. I have absolutely no problems.
But, today I downloaded the 64-bit version of Firefox 22. I removed the 32-bit version of Firefox, along with the
.mozilla folder. I then extracted the Firefox 64-bit
.tar.bz2 to my home directory and created a desktop shortcut. Firefox started okay the first time. But, when I closed it and tried to start it again, a window pops up and says Firefox is already running. I have to go to System Monitor and kill the Firefox process. Then it will start.
Can't figure out what the problems is, Any ideas?
