The other night I came across the Gnusto plugin for Mozilla, and promptly installed it in FireFox.
The first (and only) thing I tried was my own entry in the 24 Hours of Inform contest, and I was disappointed when FireFox just prompted me to download the file to disk; no different than before I had installed the plugin.
Just now it occurred to that Gnusto might expect Z-Code files to be served with a particular MIME-Type. The rec.arts.int-fiction archives didn’t provide a clear consensus, but application/x-zmachine z1 z2 z3 z4 z5 z6 z7 z8 seemed a likely candidate, so I added the following to the .htaccess file in my web server root:
AddType application/x-zmachine z1 z2 z3 z4 z5 z6 z7 z8
That did the trick. I put the URL of my .z5 file into FireFox, and after a few seconds Gnusto opened a familiar-looking Z-Machine window. It even supports SAVE and RESTORE – very slick!
