Installed 3.6.6 and found PLUGIN-CONTAINER.EXE-15EDC9DD.pf running in task manager allowing voices/music from some unknown web site to continually play even though firefox is closed. 3.6.6 is a major problem and also continually crashes! in English
After downloading 3.6.6, plugin-container.exe allows an unknown website to continually stream audio through my speakers, even after firefox is closed. I kill the process in task manager and it still relaunches itself. I found this file also running by search my computer PLUGIN-CONTAINER.EXE-15EDC9DD.pf in c:\Windows\Prefetch. When I kill that process, audio instantly stops. But it relaunches after 10 minutes or so. The process eats up lots of memory. I've had to restart firefox in safe mode several times as it crashed even before opening. 3.6.6 is majorly flawed and I'm running Windows XP. Time to downgrade to 3.6.4
This happened
Every time Firefox opened
== I downloaded 3.6.6
