1--Roboform is $30 after the trial, or WAS when i bought it, Billeo and Firefox are free.
2--Surveys--if you're using reputable survey companies, no need to worry. If a co is sleazy, don't even finish your application.
3--Your birthday can not be used to find your SS #. I was born in 1946, got my SS card in 1967. How would anyone track that? But if you're filling out forms for a shopping co, make sure the URL box is yellow (secure) when you put in sensitive info. The co may be legit, but non-yellow means the page is not encrypted.
4--There's no connection between survey gift cards and MSPA Certification. Apples and elephants. I would watch out for the gift cards, though. I did endless surveys for a perfectly legit co, and the gift card was for only $5. I quit after a while, not worth it.
5--Don't do any survey companies that require you to sign up for offers or subscriptions for other things. They're an endless loop of scamming and spamming. The legit companies are simply survey questions, no strings attached. There's a list here somewhere.
