Help Two Active Windows

Im trying to do a bot see some videos for me that I need to complete to get some tickets, but the problem is that the video only plays when the web tab is in focus, if I try to open other tab or minimize the window, the video stop playing. Is it possible to make two windows or more active or simulate that is?
I know that have one script called video.js that I sure is responsable for this function, but I dont know how to prevent from page loading this script.

Maybe this helps you :) [Only registered and activated users can see links. Click Here To Register...]

It helped a little, now the windows doesnt lose focus when I click somewhere in browser. But the problem still remain, I cant minimize or do two things at the same time, that video stops playing :/
