stop mozilla plugin prompt

Expanded from a mozdev.org FAQ:

Q: How do I stop Mozilla Firefox from prompting me to install a plugin?

A: Delete the libnullplugin.so from your Mozilla Firefox plugins directory. You may have to do this as root if you do not have write access to your Mozilla Firefox installation from your user account.

Q: But now Mozilla just shows blank space where plugin content would be. How do I know when I’m missing plugin content? (Or, how do I know when to feel warm and fuzzy because I successfully avoided a flash banner ad?)

A: Add this CSS to your userContent.css file:

embed {
  border: solid;
  border-width: 20px;
  border-color: red;
}

Now there will be a big ugly red box where plugin content would have been. Feel free to customize the size, color, etc. to your liking.

  1. Looked into the original question in this thread. This is a better option.

    about: config


    > plugin.default_plugin_disabled


    > Set value


    > False.

    You may get another annoying prompt in the place of the other, now gone one. If so:

    about:config


    > right-click and select New


    > choose integer.


    > privacy.popups.disable_from_plugins


    > set the value to 2.
