Firefox 3.6 Still Lagging in the Speed Stakes


Interesting news over at ComputerWorld where some in-house testing has shown that Mozilla’s new Firefox 3.6 – while 15% faster than its previous incarnation – still lags behind in the speed stakes when compared to Safari or Chrome. had already been pretty damning over the weekend, reporting quite bluntly that “Firefox is still miles behind Google’s Chrome browser in the speed department”.

"Even with the JavaScript speed boost, Firefox 3.6 can't match Safari or Chrome."

Launched last Thursday, 3.6 came in at number three from five Windows browsers tested. According to the ComputerWorld report, “Firefox renders JavaScript three times faster than Opera 10 and more than four times faster than Microsoft’s Internet Explorer 8 (IE8). It’s also 14.5% faster than Firefox 3.5, the Mozilla browser that debuted in June 2009, a slightly larger speed increase than Mozilla has claimed. But even with the JavaScript speed boost, Firefox 3.6 can’t match Safari or Chrome. Safari is twice as fast — and Chrome 4.0 nearly twice as fast — as Firefox.”

Safari edged Chrome for first place in the speed race, beating Google’s browser by about 6.5%. The test saw reviewers running the SunSpider JavaScript benchmark suite in Windows XP Service Pack 3 (SP3) three times for each browser, then averaging the scores to arrive at the final rankings.

Said Laptopmag, “Surprisingly, Firefox 3.6 cold and warm opened slower than Firefox 3.57. While the warm opens were only a tiny .2 seconds apart, the cold opens took about 50-percent longer, going from 4.5 seconds to 6.8. In our view, that’s a pretty big step backward. All of these open times are probably faster when you use a faster processor a faster hard drive than those found on our testbed.”

    I’ve used all these browsers and never notice any real speed differences. What’s more import is safety! If speed kills I’m not interested. Firefox is the only one with all the plugins I like, yes there is the problem with tabs memory segmentation but I know about it, and knowing is half the battle.

      I have to admit, the last time Firefox crashed on me, I was incredibly frustrated that all of my tabs were taken with it… I’m wondering if I should start taking a more zen approach to browsing… 😉

    The same happened to me last time firefox went kaboom, very annoying. Still wouldn’t have me running back to IE though.
