I am running firefox 11 on ubuntu 10.04 and every time I close the program it continues to run in the background. What worries me even more is that the flash plugin is also running in the background:
ps aux | grep firefox userxx 99999 11.4 10.3 689152 105696 ? Ssl 22:33 0:30 /usr/lib/firefox-11.0/firefox userxx 99998 0.0 2.8 333912 29064 ? Sl 22:34 0:00 /usr/lib/firefox-11.0/plugin-container /usr/lib/flashplugin-installer/libflashplayer.so -greomni /usr/lib/firefox-11.0/omni.ja 13568 true plugin
Is this normal behaviour, or even just an innocent bug? Should I be worried about malware reading and writing to my personal files?
