	Ok. I think I filled a bug report some time ago, but nobody
replied. I'm insisting on using gcjwebplugin because it's the only way
to use Java plugin with a 64bit system (I migrated my entire system to
64bit, including Firefox and there's no turning back ehhe)

	Yes, you're right. I'm used to write complete bug reports, but
I thought nobody would reply. So here we go:

1) segfaults after loading a page with an applet and changing to
another site:

	You think it's a Firefox problem, right? So if I use gdb, I
get the backtrace:

	But this is a Firefox problem, right? So there's nothing you
can do, right?

> An hint, have you tried to load the applet with gappletviewer?

	The problem is that the applet is showed but I don't know how
to get it. Is this the code which shows the applet?

<div id="layerCriptApplet" style="position:absolute; width:0px; height:0px; z-index:1; left:-2px; top:-2px;">
	<!--applet code="scopuscriptapplet.class" width="2" height="2" name="scopuscriptapplet" codebase="/scripts/ib2k1.dll/APPLET" MAYSCRIPT VIEWASTEXT-->
  	<applet code="Qz5B0MsGKq7RiToXu.class" width="2" height="2" name="Qz5B0MsGKq7RiToXu" codebase="/scripts/ib2k1.dll/APPLET"  MAYSCRIPT VIEWASTEXT>

	<PARAM name="R" value="255"><PARAM name="G" value="255"><PARAM name="B" value="255">
	</applet>
</div>

	The site is wwwss.bradesco.com.br and it's secured. How can I
download it?
