i have around 80 machine on my network and the 80 doing sync for their data on dropbox ,
am just trying to stop these thing
what can i do using pfsense ?
The LAN sync traffic between boxes on your LAN subnet does not go through pfSense at all (unless you have multiple internal subnets) and the cloud sync traffic uses port 80 so it's hard to block (deliberately!).

I expect you can use the same strategy as discussed for FaceBook here: https://forum.pfsense.org/index.php/topic,69860.msg383922.html#msg383922
I imagine if you block all those destination addresses your users will be knobbled.
But, of course, if people can connect a VPN from their computer out to a VPN provider, then they can tunnel through and then out to DropBox (or whatever) via the VPN provider - it's a losing game really trying to block stuff.
Would the Policy rules of Snort Block this?
