I contacted Quick Surveys and the said to set my browser to ananomous since it won't open "IntAPi3"settings.

Hi, what do you mean by "won't open"? Do you get an error message you could copy/paste, or provide a screenshot of? More details would be very helpful in figuring out what they might be suggesting and whether it would resolve the issue.

If you think they are suggesting using a private window, see: Private Browsing - Use Firefox without saving history.
