This is odd. I upgraded FF to 3.5.7 not that long ago but more recently - like last couple of days - all the time it is open I hear sounds indicating a process opening and then closing after a few seconds. This occurs approx every minute or less. If however I run FF 3.0.16, my last version, this does ot happen.

I have also had an upgrade to Norton Internet Security but that too was way before this problem/annoyance anyways. So - nothing comes to mind added or CHANGED that coincides with this irritating deal in FF 3.5.7.

I closed everything except this FF version and also closed all ''live'' tabs that were web connected - I also stopped traffic - an option on my bandwidth monitor - so FF sits there with one tab open running an offline page - still this crazy ACTIVITY!

I inspected all running processes for when this thing occurs but only thing I could spot was a brief change in CPU idle percentage - nothing else could be seen to change. So - any ideas? Is this browser SPECIFIC - anyone had any issues? And yet initially 3.5.7 seemed not to do this. Other thing - any other way to track down a mystical process that only lasts a few seconds?Try upgrading to FF 3.6. In earlier versions of FF I had some memory and CPU issues when it was left on for a week or so. Ver 3.6 seems to have solved some of those problems.Thx for reply - I'll try that soon as I can but for now will MAKE use of 3.0.16 as an interim.Update ....

Just put 3.6 on and - knocking on wood .... seems no repeating process. Here's hoping it stays OK.

I do have long spells between reboots and so maybe there was a memory/CPU issue after some time with 3.5.7.

Despite that - I'd be interested to know a way to track down an itinerant mystery process like I described! Thx again for the input.DLoad install and test Process Explorer.....did i mention it's FREE ? ?Thx Patio - I seem to remember trying that some time ago but IIRC found it was rather hungry for CPU time. May well try it again altho this process I referred to was such short duration it seemed hard to track down.

Fortunately having moved up to FF 3.6, the problem seems gone.I'm suprised you observed that...Process Explorer runs in the background and takes up hardly any system resources at all...
Where did you DLoad it from ? ?Forget where I got it but maybe it was the time it took to get initialized - I just seem to recall something about it being super intensive that put me off using it. RECKON I may well try it again. Thx anyways.
