Excelente bloqueador de ventanas emergentes. No se le escapa ninguno !!! He probado varios bloqueadores y este es el mas eficiente en firefox (no se si tendrá la misma eficacia en otros navegadores).

Excelente bloqueador de pop-ups (ventanas emergentes). De todos los que probé este fue el mejor.

Excelente, funciona muy bien ^^

This is an absolutely essential add-on for Firefox and honestly I'm surprised it's still not on Mozilla's official Recommended Extensions list yet.
Even with everything on Firefox set to strict I still had a bunch of unwated/intrusive/security-risk popups showing up on various sites, but since getting this add-on I even forgot those exist on the web. It's impressive to say the least. Thanks to whoever made this !

A very useful & need to have add-on when using your Firefox browser. I actually use two different ones to cut down on unwanted spam & ads which work great together & can both be found on my home page as I promote the ones I like.
