Enable Java applets in Firefox

Today I found that I need to run an Java applet within Firefox but Firefox does not provide by default (at least on my system) any plug-in for that.

I had already installed the IcedTea but it seams that my browser was not aware of that or I have no default configuration that will expose the IcedTea plug-in to my browser.

Likewise when you are configuring your Shockwave Flash plug-in into your Firefox (on Linux), you can configure also the IcedTea plug-in to enable java applets in firefox. Drop to your console terminal and type the following:

$ locate -i IcedTeaPlugin.so
$ cd ~/.mozilla/plugins/
$ ln -s  ./IcedTeaPlugin.so

So you should end up with a link to IcedTeaPlugin.so inside your ~/.mozilla/plugins/ folder.

Now, if you open your Firefox then Tools->Add-ons->Plugins you should see the "IcedTea-Web Plugin" aside other installed plug-ins you might have.

Make also sure that the button from the same panel/row as "IcedTea-Web Plugin" shows "Disable" - which means the plug-in is Enabled. If yours shows Enable then click on it to enable that plug-in then restart your browser (for the sake of the routine).

Now, if you think that this article was interesting don't forget to rate it. It shows me that you care and thus I will continue write about these things.
