Mozilla plugins refresh and stuff

To verify that Mozilla is aware of new .xpt files, you can look in the generated file, xpti.dat, where type libraries are listed. If you need to, you can call navigator.plugins.refresh() to find new XPT files and plug-in software.

Plug-in developers might find it useful for debugging purposes to turn off the exception catching mechanism currently implemented in Mozilla on Windows. To turn off Windows exception handling, add the following line into your prefs.js file: user_pref("plugin.dont_try_safe_calls", true);
