Firefox itself is a web browser and not a website nor a search engine.

The company Mozilla that makes the Firefox web browser has never had such random prizes, especially expensive ones in variations of this scam. The fake prizes have been for a Samsung S8 or S9, a $1000 gift card from say Amazon or a iPhone X.

Also if Mozilla did have prizes for something then it would likely involve a *.mozilla.org page and not some random weird name site that came up from a malvertising Ad.

This scam is to get personal information from those who fall for it like name, address, phone#, email and the fake very cheap $1 or $2 dollar shipping is to get the credit card or bank information.

Since it is a misuse of the name Firefox and or Firefox icon you can report it at https://www.mozilla.org/en-US/about/legal/fraud-report/

Mozilla has done surveys over the years by way of say https://qsurvey.mozilla.com which is surveygizmo.com however no prizes are given.

Thanks but the problem is persistent. Every time i am in Firefox this survey comes up. The following address appears and perhaps it will allow you to 'deal' with it?

I am not responding to it but it is a nuisance as it takes over my screen.

Hi Peter, does this appear in a web page as an overlay, sidebar, etc.? Or does it open as its own tab?

If it appears in a web page, it could be something pushed through an ad network or the site might be hacked.

If it appears in its own tab, it could be a pop-up from a website or an external page opened by malware on your computer.

Also could you make sure that Firefox's phishing and malware protection feature is enabled on your Firefox? When I test that URL, I immediately get a red block screen.
