The problem is solved but in a weird way. 1. sudo apt-get install --reinstall java-gcj-compat-plugin gcjwebplugin-4.1 didn't help. Appearantly no link is ever created in /usr/lib/firefox/plugins/
I checked the directory /uer/lib/mozilla/plugins and found a symlink libjavaplugin.so which was pointing to /etc/alternatives/mozilla- javaplugin.so The link /etc/alternatives/mozilla-javaplugin.so was a broken symlink to my uninstalled sun jvm plugin from multiverse. So I did 'sudo update-alternatives --config mozilla-javaplugin.so' and selected proper option. After all this I can see the gcjwebplugin in firefox (about:plugins). Also /etc/alternatives/firefox-javaplugin.so points to gcj web plugin. I guess it happened yesterday but I was too busy checking /usr/lib/firefox/plugins/ But it looks like it is not being used from anywhere, specifically from /usr/lib/firefox/plugins So, I think we should remove firefox-javaplugin.so configuration and should only keep mozilla-javaplugin.so -- update-alternatives doesn't update java plugin https://launchpad.net/bugs/66621 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
