NPAPI Plugin update doesnot work on the fly

Question

I have browser plugin built using NPAPI Lib for Safari and firefox for Mac System.Now I have newer version plugin and I am asking user to download new plugin if user doesn't have latest plugin.

after downloading the plugin it is not getting loaded and I have to close the browser and restart it.

I am doing navigator.plugin.refresh(false) at regular interval but no success.I can't reload the page at this moment because I am still getting old plugin version.

If go and kill the plugin in activity monitor and restart the browser it is showing new plugin version. Please help me on this.

Edited:

This method is called every 3 sec

function InitIEPlugin() {
plugin = navigator.plugins["MyPlug-In"];
        if (plugin) {
            remoteEngine = document.getElementById('MyPlugin');
            if (remoteEngine) {
                isMyPluginInstalled = true;
                var version = remoteEngine.getAttributeByKey("plugin_version");
                if ((ua.indexOf('Intel Mac OS X 10.5') >= 0) || (ua.indexOf('Intel Mac OS X 10_5') >= 0)) {
                    //isHarmonyPluginUpgradeRequired = CheckVersionOfPlugin(version);
                }
                else {
                    isMyPluginUpgradeRequired = CheckVersionOfMacPlugin(version);
                    if (isMyPluginUpgradeRequired == true)
                        isMyPluginInstalled = false;
                }
            }
        }
   }

Next time make sure you mention your OS in the text; I see you're on OS X from your tags, but it changes everything to know that you're on Mac.

You need to install the new version as a different filename (well, the .plugin/ bundle needs to be named differently). The easiest way to do this is just to put the version of the plugin in the filename, e.g. ~/Library/Internet\ Plug-Ins/MyPlugin_1.1.0.12.plugin

As long as the new plugin has a different filename than the old, it should work.
