Firefox Advertisements?

[Jack]

Lately I've been getting advertisements on top of websites like Facebook and Youtube logins which only happens when i use firefox. Is this cause of an add-on ??
Not really

That's what happens when you use ILLEGAL browers. Just use IE like a normal person.

Do you have some form of ad-blocking feature in Internet Explorer (or Safari if you're on a Mac?).

Firefox illegal? I'd love to hear the logic behind that one...
