What 64-bit web browsers exist for Microsoft Windows (64-bit
XP/Vista/7)? For example, 64 bit versions of Opera, Firefox or
Safari?
If such a browser exist, do you have any experience with
opening very large HTML files (opening times, stability,
memory consumption per HTML input byte).
I am asking because we have a server application that generates
very large HTML files (the record so far is 900 MB, but a
more typical size is 100-200 MB) and users often run out of
memory when trying to open the HTML files. The current
practical limit is about 130 MB. The memory consumption is
about 10 times the input HTML file size (but this may of
course depend on the kind of HTML).

There is a 64-bit version of Firefox available. The browser itself works fine, however there is a severe limit of plugins available, no Flash for example, although I believe they have just released a 64-bit Java plugin.
64-bit versions of Windows come with a 64-bit version of Internet Explorer, but again you meet similar limitations with Flash and Java.
So, using these versions may assist in your application, but it's going to restrict users in what else they can do and will end up going back to their 32-bit version for other browsing.
