I don't choose browsers on the basis of security. I run behind ZA free on a
dynamic IP. There are usability, compatibility factors and speed, that make
me choose FF over any other browser. It renders webpages faster than
anything I've seen - since I'm on dial-up it does make a difference. It
supports tabbed browsing and those exciting extensions that enthusiasts keep
developing. And it renders them right, unlike Opera. These are the things
that draw me towards a browser - Security is not an issue here and I don't
need that nagging Security Center and its service either. As for pop-up and
adware blockers, I remain faithful to AdMuncher - Cross platform, cross
browsers, Messengers, Download Managers everything is effectively blocked by
this 177kb tool.
