Is there a way to block pop-unders in Mozilla suite? I know how to block pop-ups, but it seems like an awful lot of sites lately are using pop-unders.

Mozilla suite is NOT firefox. Don't be confused. Mozilla is the grand-daddy of firefox. I'm not interested in firefox answers.
thanks!

Turn off JAVA script in the Browser

No longer supported, Proxomitron The Universal Web Filter might help.

hmmm. yeah- that would would work, but then essential java capplications would be stymied as well..... I will think about it. thanks.

Using about:config with Mozilla Suite you can set "privacy. item".
Set "privacy. popups. disable_from_plugins " to; 2: blocks popups from plugins
This does not stop everything. many Flash pop-up / pop-under still get through.

There are other settings that might help you. You will have to experiment.

Search Google for about:config Mozilla
