Topic: Firefox users - read this
After a recent Firefox update our script that prevents websites from breaking out of the frame does not work anymore. If you don't want to change browser or skip such ads, here's what you can do:
1) Open about:config
2) find dom.require_user_interaction_for_beforeunload parameter
3) Set it to false
It will return browser policies in regards to frame breakers to a previous default.
Best regards,
