Is there a way to block FLV player from popping up?

Is there a way to block FLV player from popping up? It pop up when you might visit a questionable but not illegal video playable website. Especially websites that have a lot of ads. I done all the malware test, so I am not infected. It strange that it only happens with firefox 30.0

I have mine uncheck. I wonder if background service has been comprised, remember Mozilla is open source.

FLV is for flash video which is what most internet video is. What, exactly, do you mean it pops up?
You don't need it and likely came along with something you downloaded and installed. Remove it.
Remove FLV Player, removal instructions

No, it is the pop-up to trick you to install the flv player, and I don't fall for that. It makes me wonder if those sites that have the flv player are legit, at the least the site maybe questionable. I even seen some site look like an official news site but still open a pop-up asking you to install the flv player.

I also have Microsoft security essentials.
