I've a Dell d/top, running Win XP SP3. Clicking on F/F icon produces the FF screen which rapidly vanishes and is replaced by the same scree a moment later. Looking in Task Mgr, I see FF.exe twice in Processes running. Takes up a lot of CPU apart from anything else, but why is it doing this? As a follow-up, when I use CCleaner it asks me to close down FF even though I haven't booted it up.

See Basic troubleshooting and Diagnose Firefox issues using Troubleshoot Mode, my first thought would be to consider malware but also see How to stop Firefox from making automatic connections

Also try running firefox from the command line as

  • firefox.exe and as
  • firefox -safe-mode
