Ok, I didn't know that unchecking "enable content blockers" didn't include Ghostery. How did you discover that? Though usually I check "disable extensions" under the Develop menu.
I used to use the Develop menu, but I found its forcing every open page, rather than only the one in which I was interested, to reload too much of a nuisance, so I switched to the Website Settings icon and learned about Ghostery in a lucky "Hmmm... I wonder" moment.
What do you mean by Apple locking things down?
I mean that they keep ratcheting up Safari's security features (and I've got no idea if their new "features" actually improve my total browsing experience, not just its security, or detract from it by forcing me to use Firefox on websites with which Safari is unable to deal).
I do get disgusted with them from time to time, and whenever I call them with AppleCare, the first thing out of their mouth is that I need to update to the latest version. I know that doesn't take care of everything and especially if it worked before (unless they are messing with prior versions on our computers. I don't even know if that's possible.) One thing that Firefox has that I like is an add-on that lets you know which YouTube videos you've already watched. That is handy, especially when I'm researching something. Safari does no such thing.
In Safari's case, updating to the latest version almost seems to be more likely to cause grief than joy these days.
I've looked at Firefox time and time again (thanks to grelber), but I just don't like the way it "flows" as compared to Safari; I'm willing to put up with switching to it occasionally, though, if it saves me from having to use it full time. But I may be forced to switch if the new AdBlock app doesn't incorporate the "Block an ad on this page" functionality that makes the extension so GREAT, because the Firefox AdBlock add-on does.
