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.

There's a tiny but very useful tweak in the RC version of Internet Explorer 9: if you have a URL stored on the clipboard, typing Control-Shift-L will automatically open it in the current tab. That's a nice little time saver that we hope a few other browser developers decide to copy.

IE9 has some handy new features like jump list support and a pleasingly minimalist interface, but it can be tricky to get the menu bar on permanent display if that's your preferred option. A group policy tweak should fix that problem.

Has Microsoft learned its lessons about building a better browser? It doesn't take long with Internet Explorer 9 beta to see that they have. Right now the beta is showing outstanding web render speed (thanks to GPU acceleration) plus very good standards compliance. And it's getting better with every revision.
