Firefox Beta Scores 93 On Acid3 Test 282

CodeShark writes "Mozilla released their latest Firefox 3.X beta today (3.5b4), and increased their score on the Acid 3 test to 93 [on my XP laptop], with tests 70, 71, and tests 75-79 being the final challenges. Curiously though, the current release of the top Acid3 performer — Safari — still not only rates higher (I got scores of 99 once and 100 most of the time) but is usually faster by a little (1.1 sec avg. vs. 1.4 over ten runs apiece) but only because the new Firefox beta was all over the map — frequently better by 25% (.85sec) or tanking badly with rendering times in the 2.5 — 3 second range, and both suffer performance hits on one test (#69)."

    Presumably the test should take about the same time to run each time, right?

    Also, how can Safari's score change from 99 to 100 without any changes in the code? Is this a bug in Safari?

      One of the 100 tests is JavaScript garbage collection. A garbage collector that uses tracing without reference counting isn't necessarily guaranteed to finish in a given amount of time.

      One of the tests is related to rendering speed (#69) not design faults. That's because it wants the test to be completed fast enough to achieve 30fps.

      Under system load, or browser load (such as extra stuff being done in the rendering thread whilst the test is running), a browser may not always pass this test. Whilst its an OK test, there will be no way to reliably pass it 100% of the time, and as CPU's become faster and more efficient, its likely browsers will pass eventually regardless of if they optimise their code or not.

      Its also one example of why the ACID tests are quite overrated.
      • I never understood why did they include speed in a browser test? OK, a browser should perform rendering as fast as possible, because the web is starting to demand it, and web developers are abusing scripting a lot, but it would mean that the best browsers would fail on a slower computer, and the worst would pass on a faster one. This is not objective.

        Not to mention that setting a threshold for speed is impossible. Who says how fast is fast? If the web developers have use decent and modest scripting, it will

          Because if you can't do it quickly it isn't functional. It's just like specifying video has to play at a given, acceptable frame rate to pass a test that confirms something can play said video. Playing it jerkily in an unwatchable way is not good enough

          Which is why the ACID tests each specify reference hardware, like most respectable test suites do. That is objective. Just because you don't have or use that reference hardware and run the test more informally does not mean it is a flaw with the test instead

        I don't follow your logic. They test whether, under load, the js engine responds quickly, and for you that's 'overrated'?

        Sure, in a year the hardware will allow us to deprecate the test, but right now (and at the time the test was developed) it does not.

        At the very least, the test says 'Don't assume you can always have 30 fps displayed', which is a useful -if perhaps obvious- notion.

      It's not normal for either Firefox 3.0.x or 3.5 beta to crash on ajax sites. If you are getting crashes, look up your crash reports [mozilla.com] and search for your crash signature on Bugzilla [mozilla.org].

      Plugin crashes (eg. flash) are among the most common, but corrupt files and spyware on Windows machines have also been known to cause them. If you are getting a specific crash that can be reproduced, either file a bug or comment on an existing bug with details.

    First of all, I'm not trolling.

    Secondly, Firefox is my favourite browser, and I use it as my default both at work on my Windows workstation and at home on my Mac.

    Having said that, with two corporate giants with deep pockets, and their respective browsers making solid improvements with every version, I'm wondering if it's just a matter of time before Apple's Safari and Google's Chrome become better than Firefox, which is essentially a community effort. That's not to say anything bad about the excellent work that Mozilla's programmers have done with Firefox, but they're doing so by drawing on fewer resources than those two large corporations.

    Granted, Microsoft also has a lot of resources to draw from, but they also let IE stagnate because they thought they had a browser monopoly.

      I use Firefox as my default browser too. I used to love it, now I tolerate it. Were adblock and flashblock available for Safari or Chrome (and I believe this is in development for Chrome), and were Chrome available as a Mac version, I would stop using Firefox overnight. Truth is as a basic browser these two are better already, as is IE.

      Firefox is dangling by a hair on my machines. It is entirely their own fault. They have ignored fundamental problems with the browser since version 1.0, and spent far too much time developing "features" that should have been add-ons. It's never really worked well on a Mac either. There seems to be a lot of Netscape influence in Mozilla, this is exactly how Netscape failed

      If Firefox 4.0 isn't multi-threaded and significantly stripped down, you can pretty much kiss it goodbye. This is a terrible shame. I want to continue to support it, however the Mozilla team is shooting itself in the foot far too much.

At the very minimum, put a 3 second wait on it (with a link for the impatient) or, better yet, set a cookie so that if I revisit on the way back within a short period of time it won't redirect.

    As I appear into my crystal ball, I see that Firefox 3.5 is released and still achieves 93/100. Wow, I'm a psychic!

    Ffx 3.1/3.5 has been sitting at 93/100 for over 6 months, and the devs have stated *numerous* times that achieving 100/100 on Acid3 is NOT a priority for the 3.5 release, largely because implementing SVG fonts (https://bugzilla.mozilla.org/show_bug.cgi?id=119490/ [mozilla.org]) for the purpose of passing those last few Acid3 tests is a much lower priority than other things they're working on (like javascript JIT). Why your summary of the 3.5b4 release focuses on something that literally hasn't changed in several beta releases is beyond me.

    So, can we please move on now or are you going to switch to Safari because of that newfangled Youtube interface that implements SVG fonts? Oh sorry, I was looking into my crystal ball again and saw the web circa 2025.

    • You know, it's kind of ironic that IE helped to ruin the web by supporting fancy new features over compliance and what is Firefox doing? Making Javascript faster instead of working on SVG fonts, a feature that we desperately need to get rid of stupid hacks like sIFR (which is still better than dynamically generated image headlines, whose text is not selectable.)
