Probably the more correct answer is that its less about the browser itself and more around the underlying components that are part of plumbing. There is a post from the ie team a while ago on ie8 64-bit, most of it would still apply.

Good one, Jorke! Does IE9-64 crash less often? As for Add-ins, there isn't even a release-version Adobe Flash Player for 64-bit (there is a beta), so - to answer the "speechless" response - I haven't had a satisfactory rationale for a 64-bit browser. How many browser "manufacturers" have released a 64-bit version? And Silky - yes, I run 64-bit stuff where it is available, though (as you would realise if you bought a machine in the last couple of years) supply of 32-bit mainboards / processors is the exception now. ________________________________ Ian Thomas Victoria Park, Western Australia ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Jorke Odolphi Sent: Thursday, March 24, 2011 4:24 PM To: ozDotNet Subject: RE: [OT] Why IE9 64-bit? That's an easy answer.. for all those websites that use more than 3GB of your systems RAM.. :) From: [email protected] [mailto:[email protected]] On Behalf Of Ian Thomas Sent: Thursday, 24 March 2011 5:09 PM To: 'ozDotNet' Subject: [OT] Why IE9 64-bit? A Q for Friday. Why would anyone want a 64-bit browser? I'm quite content with IE9, and installed the beta some time ago. Firefox-Opera-CHROME don't interest me now that IE handles MHT file save and load better, and I'm inclined to agree with David Connors that browsers became ho-hum a long time ago (well, that's my extension of his remarks about IE and Netscape). Just installed the final IE9 release, and the "beautiful" (ugh) website detected my 64-bit CPU (I assume) so I downloaded the installer stub and completed the install for the 64-bit version, but I was reminded by that that both 32-bit and 64-bit versions are available/installed (for all the IE9 releases I have tried). afaik 32-bit is loaded by default by Windows 7, and I can't see that a user would gain from running the 64-bit version when all 32-bit apps that don't use / address more RAM function fine with Win7. Anyone? ________________________________ Ian Thomas Victoria Park, Western Australia
