(Update, this does not work as of now, let me see if I can find a workaround)
As of now, the default Sun Java packages in Natty, will break WWER. You need to downgrade to 6.22.
Make sure the all icedtea-* and openjdk* packages are deinstalled through synaptic.
Go to http://archive.canonical.com/pool/partner/s/sun-java6/
Download (swap with amd64 for those on 64bit):
- sun-java6-bin_6.22-0ubuntu1~10.10_amd64.deb
- sun-java6-jre_6.22-0ubuntu1~10.10_all.deb
- sun-java6-plugin_6.22-0ubuntu1~10.10_amd64.deb
These has to be installed through command line:
Close Synaptic (if open).
sudo dpkg -i sun-java6*
Open Synaptic.
Choose these three packages and choose Package -> Lock Version
Restart firefox.
NB: If you get the 'Downloading WWERS' box, this might fail at about 80%, so you need to redo this until it succeeds and fully downloads. This took me about 10 tries...
