Hi,

I was using nspluginwrapper to run the citrix ica client in Firefox 2 on 64-bit Kubuntu 7.10 and the ICA plugin appeared and worked fine. I installed the plugin using the command:

nspluginwrapper -i /usr/lib/ICAClient/npica.so

Since I have upgraded to Kubuntu 8.04 and Firefox 3.0.3 the Citrix plugin fails to appear in about:plugins. Has anyone got this working or an idea why it doesn't. The acroread and flash plugins work OK.

Thanks

Murray

Hopefully, it's just a matter of symbolic linking. Please post output of:
ls -la /usr/lib/firefox/plugins
ls -la /usr/lib/firefox-addons/plugins
nspluginwrapper -l
