I'm using Firefox + searchbastard addon to do a multi-search on shopping search engines.The pages are part of a frame. This works just fine for all sites I tried so far except for shopmania.com.

If I use noscript to forbid scripts from the shopmania domain name then everything stays in place but the part of the website elements become nonresponsive. I know there is an option in Firefox to force links that open in a new window to open in a new tab. Is there something similar to prevent websites from popping out of frame? Maybe a Firefox addon that blocks these requests?

Or at least can someone please tell me what is causing only this website to act like this?

EDIT: What tool can i use to pause firefox OR javascript and stepthrough code like in c++ ? I tried a javascript debugger and firebug. They don't help but i'm probably not using them right..

EDIT2: I tried this greasemonkey script : https://userscripts.org/scripts/show/92424. It does not work so i guess it isn't because of 'target' attribute

This is wrong. I'm guessing you're using a plugin to capture and override the output some site gives you. I'm pretty sure this violates their ToS and it's not a very nice thing to do in general.

JavaScript is not designed to allow this kind of meddling. It's patchy at best.

If you want to use the data from a website, to aggregate or display in some manner, use their public API. If they don't have a public API they probably don't want you to use their service in such a manner.

The solution : I took the script from Stop execution of Javascript function (client side) or tweak it and modified it to search for the tag that has in it top.location = location and then appended a new script with the if (top != self) {top.location = location;} line commented . Being a js total newbie i don't know if it's the most elegant choice but it soves the prob. Special thanks to Tim Fountain.
I will leave this open just in case someone else will suggest a better solution, for my and others's education. Again thanks for the help.

there are some escaping issues with the cdata part in the code.So SO does not allow me to post the code. EDIT: fixed
