I have used Firefox with NoScript for some years and I don't see banner ads at all.
Among other things, it stops things such as that complained about by Expatrick; the unwanted ads relating to your recent search. mine is barring googletagservices.com.
As I look at this site, I have blocked unwanted scripts from amazon-adsystem.com, internetbrands.com, indexww.com, sonobi.com, ibpxl.com, scorecardresearch.com and googletagservices.com.
These are all inhibited from running by default. Some sites will need various odd scripts to run and I have to allow them but better that than allow sites to run all manner of unknown scripts.
As for the "Adobe Flash needs updating" thing, I rely on Firefox to tell me when this is so. Basically, when Adobe Flash is found to be out of date, a security risk etc., Firefox refuses to run it as an Add-On and tells me I need to go to Adobe's site to get the latest version.
