PPRuNe Pop : To avoid those "bl***din pop-ups", just refrain from using M$IE.
Opera (
http://www.opera.com), Mozilla Firebird (
http://texturizer.net/firebird/) and Netscape 7 (
http://www.netscape.com) have a built-in control of pop-ups.
Opera 7.1 has some difficulties with some non-standard javascript (for which I switch to M$IE or Netscape), but, generally speaking, it is a very nice brower. Haven't tested Mozilla Firebird yet.
