Safety and Security of Safari

Hi folks. This is just an inquiry about the supposed safety of Safari browser. I sometimes see comments on these forums and others, by very enlightened posters disparage the poor security of Safari. Now lord knows I'm certainly not knowledgable enough to differ with that opinion as I have a great respect for these experienced highly rated forum members . But I am curious what failings are present? One thing I've noticed while using Safari and alternatively Firefox and Chromium with Little Snitch operating. Now wait, I know the usual rant and caution about using Little Snitch. Let's just say I'm willing to put up with it 's annoying interruptions. Now my experience is, There are far far less of Little Snitch's alerts when some cookies or programs wants to phone home when using Safari, compared to 12-15 attempts to call home that the other top rated browsers (not chrome) will generate on the exact same sites I use daily. All the browsers are running AdBlock Plus and Ghostery or similar extensions that are known to be effective. But none of the extentions block the sites Firefox loads from making ridiculous number of connections that are not relevant and down right intursive. Even without these extensions running Safari generate far less connection attempts. I can only conclude Safari somehow those not allow the sites to load the part of the page that intiates these troublesome calls home. If true wouldn't that be a big plus in favor of Safari? Am I off base here? I have observed this on a number of my Macs running different OS's from 10.6 10.7 10.8 and 10.9 all properly updated. Please If you have information I am missing, take a moment to explain what's happening.

Thanks for your consideration.
