I figured i'll make a useful post this time!
If you use chrome, and want to get rid of all those pop ups and blocks then do the following:
1) click "settings"
2) click "extensions"
3) you will not find your desired extension there, so click "get more extensions"
4) scroll down to find something red that says AdBlock
5) double click and install it, then you can enable it in extensions if it wasn't already enabled
I love this, because I hate those popups I get when I download things, or those annoying interruption in youtube. I also hate that most ads are about half naked ladies and dating sites. bleh!
you are welcome!
