It does sound scammy. Did that appear out of a web page or as a new window or new tab?

Do you have any unrecognized or suspicious extensions on the Add-ons page? You can check using either:

• Command+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then, if in doubt, disable or remove.

You can attach screenshots to a reply to yourself here. Make sure to edit or blur out any sensitive information before saving the file and attaching it to your reply.

There you go, making up words again. LOL http://dictionary.reference.com/misspelling?term=scammy

Thanks a lot for your reply guys!

@jscher2000: Any suspicious extensions on my Add-ons so far.

So basically, Firefox never ask people to fill in surveys, right? Or am I wrong?

Screenshots of the "scammy" webiste now attached.

Thanks guys!

Mozilla has some surveys. If I load this site in a private window (so it doesn't know I'm logged in), I sometimes get a message that I'm selected for a survey. The link leads to a site with surveygizmo in the address. No credit card information required.

A web search for the telephone numbers involved; as on the images; would tend to confirm the obvious that they are scammy. Some of those hits were themselves rather dubious
