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?
