It blocks the startpage about:blank of Firefox 56.x . The new version Firefox 57 I will NOT install for the horrible unusable new design that can't be changed. So Adblock Plus became unusable for me.

very easy to install!
open code
free to use

The latest version is a totally garbage.

Супер!!!

I've rated it 5* because I've gone back to legacy versions of both Firefox and Adblock Plus - now the 'element hiding' option works as it always has done. Firefox 'nags' me to download the latest version (have disabled the automatic download to get round this) so I can enjoy Firefox as it used to be. Hopefully the developers of Adblock Plus will eventually work out how to code with the newest versions of Firefox.

Me encanta es una bonita aplicacion para todos esos anuncios molestos en internet!
Lo recomiendo 100%

Great, and helpful!

poco funcional la instalacion
