Seems to work just fine on all pages i visit, including FB and YT, but can't disable the ''Allow some non-intrusive advertising'' option permanently ! I click to disable it but if i return to the ad-blockerPro option page he's enable again ! But i think it's not a problem ! The problem is all this ad-blockers add-ons saying that they work and once one visit a page get a big ad-block detected square and it's impossible to view the page without disconnecting the add-on ! Yours is working fine so far so... thank you, pcvark !
