So, you are looking for something online, find the perfect site, and discover it is blocked by a survey pop up and disables interaction with the page behind. Well, this is how you bypass this:
1) Have FireFox
3) Go to the page you want to access, and RIGHT WHEN THE PAGE LOADS click the blue "X" button that stops loading the page. As you know when you go to a survey-blocked page there is a split-second BEFORE the survey box actually appears; click "X" before it comes up!
4) Since you press the "X" button before the survey appears it prevents anything from loading further than the page itself, so you are free to interact with the page!
