Is it possible somehow to install more than one version of the same plugin in Firefox?
I need a very specific old[ish] version of the Java plugin to run an Oracle applet, can I install this version *and* the latest version?
N.B. the applet *doesn't* work with the latest version of the Java plugin, it looks for jpi-version=1.4.2_16 specifically before it will even try and start. OK, this is stupid but I can't do anything about it.
