How do I enable support for Netscape plugins?
Most binary distributions come from Netscape plugins support enabled, but if you compile from sources, you need to install lesstif, remove config.cache and re-run configure, in kdebase (check that it compiles the contents of kdebase/nsplugins/). If the auto-detection of the plugins fails, try running “nspluginscan” from the command line.
