Safari passes the Acid2 test

On October 31, Apple released Mac OS X 10.4.3, which brings Safari to version 2.0.2 (416.12). With that update, Safari is the first officially released web browser to pass the Acid2 browser test. As far as I can tell, the update also fixes Safari’s “Flash Of Unstyled Content” problems (which I mentioned in Safari Wishlist) that occurred on some sites, especially those that display Google AdSense ads.

Thank you Apple, for working so hard on making my favourite web browser even better! So, how about making form labels clickable? ;-)

Update: More details are available in WebKit Fixes in Safari 2.0.2 / Mac OS X 10.4.3.

    When I resized the font size the smiley face exploded. Didn’t read through the “guide” to see if that’s acceptable though.

  2. Safari Rocks! But is there a way to increase the number of rows in the bookmarks bar? If there is, I can’t find it… my only gripe.

    I’ll second making form labels clickable… I mean, come on.

  4. I still see the FOUC after upgrading to the most recent Safari update, not only on your site but as well as all the others that had reported seeing it. I don’t think it’s been fixed. Bummer.

    Andrew: Hmm. I can’t remember seeing the FOUC since upgrading to 10.4.3. Maybe I’ve just been lucky ;-).

  6. Kenzie: The test assumes that you haven’t changed the font size.

    For user agents that support font zooming, it also assumes a zoom factor of 100%. (Acid 2: The Guided Tour)

    Andrew: I can confirm that the FOUC problem has indeed not been fixed. It doesn’t occur consistently - I’m guessing that it may depend on the content of the AdSense ads.

  8. This new version suits me the best. Of course there is stuff to work on but in general it works good.

    I still get the FOUC as well, even with a much newer version. However, on my site it has the added effect of NOT displaying the layout properly once the CSS is applied. Refresh using Safari until you get the FOUC and the whole top bar should appear really weird.
