Firefox +Java = 100% cpu and crash

[user1]

Using: Firefox-3.5 for Ubuntu 9.04, and Adblock+ 1.1

I noticed that when you go to this page:
http://midp-calc.sourceforge.net/Calc.html
and try the demo applet, it makes Firefox use way too much cpu, and crash.

If no extensions are running, it seems to run fine, but having Adblock or Noscript enabled crashes it.

Hello.

This issue was SOLVED here,
comment #6 at https://bugzilla.mozilla.org/show_bug.cgi?id=501173#c6.

Change the plugin firefox uses for java, from libjavaplugin_oji.so to libnpjp2.so.
Done.

For a system wide change:

Code: Select all

# rm /usr/lib/firefox/plugins/libjavaplugin_oji.so
# ln -s /usr/lib/java/jre/lib/i386/libnpjp2.so /usr/lib/firefox/plugins/

Hope it helps!
