You should be able to get any version of Firefox, and in fact, if you search
your Mac applications directory you will probably find it. Just start it.
OK, I have run a little test:
1. Monitor the Java Cache before and after starting the browser and loading
http://chemapps.stolaf.edu/jmol/docs/examples-11/new.htm
2. Close the browser
3. Repeat step 1.
4. Close the browser
5. Upload a NEW caffeine.xyz
6. Repeat step 1.
Findings:
1. Java never "clears its cache." It just stores the file and the header
that came from the server associated with that file. That header contains a
date.
2. It looks like Java just first sends a message to a server asking for a
header, and if the header matches the one in the cache, then the file is not
downloaded, and the cached file is used instead. This is pretty standard
operation.
OK, so why the security bug? Obviously it is a Firefox bug. Doesn't happen
in older browsers; only appears with Mac 3.6.8. You need to respond to that
bug report reply and be very clear about that. It would be especially good
if you have verified that it all works with Firefox/Mac 3.5.7.
The bug is this (if you can confirm it on your Mac, Phil)
Observation: Java applet running in Firefox 3.6.8/Mac specifically hit a
security violation when trying to read a file that was previously cached in
a prior browser session.
Comments: This bug is specific to Firefox 3.6.8/Mac. It does not appear with
other operating systems and it does not appear with Firefox 3.5.7. All works
appropriately within one browser session, but after the browser is closed
and then re-opened, the applet cannot access any locally cached data file
from that previous session opened using Java's URL.openConnection() method.
