It turns out that Internet Explorer 9, in its 64-bit version, apparently has a different, slower JavaScript engine than its 32-bit counterpart. We didn't know that when starting our browser tests, but we've now updated our tests with IE9 32-bit results, at least in the JavaScript and CSS categories. Doing so gave IE 9 32-bit an edge in at least one category. Thanks to commenters and Twitter correspondents who pointed this out.


It has been quite a month for browsers, with Internet Explorer and Firefox both dropping big new versions, and Chrome and Opera continuing their regular improvements. We tested all these browsers' startup and tab-loading times, JavaScript powers, and memory use for your fast-minded enjoyment. Update: With 32-versus-64-bit IE 9 results.


Internet Explorer 9's use of application reputation to warn users that they're installing software which hasn't been widely tested is a familiar tactic, albeit one that's previously been the domain of security software. If you're regularly testing software that changes frequently (such as the Chromium project on which Chrome is based), that tactic could becoming annoying fairly quickly.


The final release version of Internet Explorer 9 should hit Microsoft's servers at 3PM AEST today. It will also eventually appear for Vista and Windows 7 users via Windows Update, but that process may not happen for up to 12 weeks. We were quite taken with IE9 in beta, and even if your own browser allegiance goes elsewhere, at least your non-tech relatives will likely soon have an HTML5-compliant browser.
