'special offer' appears/preempts all pages, even in private.
firefox starts normally, loading yahoo, which is my start page. Then, over top of the page, a 'special only for today, only for you' offer appears. It says it is from Mozilla, and claims that, if I take a short survey, I get a free Iphone. There is no way to shut this off, or remove it from the page. I tried opening new windows, with known addresses- they atart to load, then the 'free phone' thing comes up over top of them. I tried Explorer and Chrome, and the same thing happens, just with the survey being attributed to microsoft. This is the second day this has happened. I was able to log into my email, and that worked ok, but nothing else is possible. Please help!

That is not from Mozilla.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Thank you. I ran the malwarebytes and microsoft safety scanners so far, and, as you said, each pointed out different things. Today the problem has not appeared but I am sure it will come up again, so knowing how to handle it when it does is very helpful. Thanks again!
Glad to help. Safe Surfing.
