Hey guys, There is something happening in my laptop with both these two versions of firefox: when I close it, it continues running as process, using cpu, memory, etc. I have to use AnVir TaskManager to end the process, otherwise it goes on and on. If I don't stop the process this way, when I open firefox again it starts another process. When I check with TaskManager, it shows 2 firefox.exe running... This does not happen with version 10.2. That's why, after using for a while version 11, I went back to version 10.2. Now, I've been using version 12, and it happens again. I already uninstalled a program that was installed with firefox (optional), called Mozilla Maintenance Service, but the situation is the same. Has anyone experience the same thing? Do you know why it happens? And do you know how to solve it? Thanks in advance for any suggestions.
