I'd go along with NoScript being a very powerful security extension, maybe more so than one's installed security on some pages, that a decent security app wouldn't allow to open w/out a warning,
It just takes some getting used to on some sites, is one has to let 10 or more items have temporary access to see the page, then something's up & it may not be worth the risk to see the content. When I use Firefox, there's only a few whitelisted sites, the rest I allow on temporary basis, as needed. It works the same on both Linux & Windows (don't know of Firefox is available on Mac, so can't comment there).
I highly recommend the NoScript Security Suite for all Firefox users. rp88 is correct, it does make an excellent adblocker, as these comes from 3rd parties. If the publisher of these ads aren't whitelisted (who would want to), then they're not going to be seen. This also makes the content that one wants to see load faster. NoScript happened to be one of the first extensions for Firefox that I put to use. Adblock Plus was the first, as I recall.
If I were to disable Adblock Plus, the page content would change little, if at all. In fact, I just opened the Firefox browser & that was the result, though Ghostery is still enabled & will leave it there & on Chrome, as it has the ability to block social sites & many other trackers.
However I still say that NoScript is the best at script blocking, which includes most all ads. Would like to see a version for other browsers, but it's not likely to happen. I cannot comment on the script blocking extensions of Chrome, as I've not tried any of those.
