Thanks for your view on this, DavidR,
Well the avast extension has been in all of my browsers,
as a steady companion I would rather not be without.
How else could I have commented on FP's here? 
Where you are absolutely right, is that a minimal amount of extensions,
means a less outstanding identifiable browser configuration.
Probably there just is a basic need for ad- and script-blocking in some way or other.
Only the very lonely will sit and wait for the nexct commercial message.
"Go with the flow" is the best policy for the average browser user to stay under the radar for the moment.
Problem with browsers is data slurping, tracking and of cource governmental control and surveillance,
and in the existing heydays of Big Brother overall end user concerns have grown.
Such concerns certainly turned up since the turn of the century.
Good to pause certain analytics in a sense; there LocalCDN extention comes to mind.
But everyone should work his or her or it's browser as to the best of his/her/it's liking,
that should be imminent, parental-control or not.
Stay secure both offline as online as well,
polonus
