The last three Java updates installed Jave Console extensions that won't uninstall using the supplied "removing addons" document. Java offers no help. How can I remove them?
In firefox 3.6.13 32 bit on Windows 7 64 bit with WOW subsystem, under Tools > Addons > extensions I see four Java console entries listed. They are: Java Console 6.0.20, 6.0.21, 6.0.22 & 6.0.23. 6.0.23 is active. The other 3 are disabled with the Uninstall button disabled. There are no extension folders in the default profile (only profile listed). There are not programs listed in the Windows Control Panel Remove programs pane.
You would have to clear those out thru the Windows Registry, they aren't installed into Firefox.
From what I have heard, Java is supposed to have fixed that problem with the upcoming 6.0.24 version.
Since I am unfamiliar with registry editing procedures, I used the manual removal process of deleting appropriate sub-folders from c:\Program Files (x86)\Mozilla Firefox\extensions. After stopping Firefox and restarting it, only the desired (Java Console 6.0.23) extension appeared in Tools > Add-ons > extensions. Problem solved! My thanks to both cor-el and The-edmeister for their helpful responses!
