         | 
         | Correct.
         | 
         | FWIW (disclaimer: I'm the developer of StopTheMadness Pro,
         | mentioned in the article) I just ran two tests in Mac Safari,
         | with StopTheMadness Pro enabled and disabled, and the results
         | were exactly the same each time: "at least 18.06 bits of
         | identifying information". Alas, that's a unique fingerprint,
         | but apparently my extension doesn't make anything worse. If you
         | look at the detailed results, the identifiers are things like
         | User-Agent, screen size, time zone, and language.
        
           | Etheryte wrote:
           | That's the same amount of bits I got with every browser I
           | tried (Safari, Chrome, Firefox). Not sure what the takeaway
           | is, but at least for me, all browsers seem to leak roughly
           | the same amount.

           | One relatively small complaint if you don't mind me hijacking
           | this thread. The update process could be a lot better!
           | Especially on Firefox. I'm used to it now, so it's become
           | just a bit of an annoyance but the first few times were tense
           | moments, and especially panic inducing a couple times when I
           | was pressed for time and couldn't use the browser before
           | updating the extension.
           | 
           | In any case, it's an awesome extension and I recommend it to
           | others frequently!

       | Two little-appreciated privacy features in Safari not mentioned
       | in the article:
       | 
       | Each private browsing tab has its own cookie / data bucket[1];
       | and
       | 
       | Private browsing tabs and windows are preserved across restarts.
       | (This is optional and can be configured to forget them upon
       | restart.)
       | 
       | These make it practical to use private browsing for nearly all
       | browsing, which isn't really the case in other browsers, where
       | private browsing is clearly designed as an occasional-use thing.
       | (And of course if you use private browsing for most things, you
       | can still open regular windows for sites where you want to stay
       | logged in.)
       | 
       | [1] If a link or script in a tab opens a new tab or window, then
       | they share the same cookie bucket. This preserves compatibility
       | with sites that require such a flow.
