Firefox 3.1 is the latest to pass our selectors test

I’ve just put a pre-Alpha build of Firefox 3.1 through its paces, and can confirm (following David Baron’s announcement) that it gets a score of 578/578 in our CSS3 Selectors Test, which means not only support for the new selectors, but some bugs fixed in existing ones. To put that score in perspective, Firefox 3 scores only 357/578.

There is an almost perfect score on Daniel Glazman’s Selectors Test too, with only one discrepancy showing up.

So Safari, Opera and now Firefox all pass the test; of the major browsers, that only leaves one Inevitable Exception…

Those brave enough to try pre-Alpha can download builds from Mozilla’s FTP server. The usual warnings and disclaimers apply!

    Have you tested IE8b1?

  2. Lea Verou Says:

    I was always wondering, why IE always is the problem.
    Is it that hard to implement new css selectors and properties, or they just don’t care?

  3. Peter Gasston Says:

    I don’t have a machine with IE8 to hand, so I can’t run the test at the moment, but IE’s current CSS support document says the selectors are not supported yet. I’ll try when I’m at work.

  4. David Naylor Says:

    How does the 3.1 nightly do on the Acid3 test?

  5. Henrik Says:

    Lea Verou: The problem with IE is that Microsoft got monopole in the Browser market. Why should they care, they basically control which standards are getting widespread usage.
    The only thing we can do is: Sending a letter telling them they are 5 years behind in standard support, stop caring make your websites for FF, Safari and Opera and at last make plug-ins that give the features we want (Only a good idea if you want and support).

  6. Peter Gasston Says:

    IE6 scores 276/578, IE8B1 scores 335/578.

    FF3.1pA gets 74/100 on the Acid 3, which is a slight increase over FF3’s 71/100.

    Statpr0n!

  22. Alan Gresley Says:

    Well done Mozilla.

    My major concern is the mess with empty substring matching selectors and how changing the way that these selectors are treated now results in the ability to now target Gecko 1.9.1 alpre or the future FF3.

    The amount of time that as be devoted by Mozilla and the CSS WG about these weird and wonderful selectors is amazing and I see it as just wasting time on something that should not be an issue. There are even use cases.

    img[alt="large"] {…}
    img[alt="small"] {…}
    img[alt*=""] {…}

    Come on Mozilla and the CSS WG. Time is ticking away.
