Sometimes when you visit a website you’ll see an “Additional plugins are required to display…” notification at the top of Firefox. Usually it is because you legitimately don’t have the correct plugin to view content on the website (such as Flash player) but other times it may be because the website wants you to install something malicious. If you’ve chosen not to install Flash or other plugins, you’ll see the “missing plugin” notification all of the time. So, lets fix that and get rid of the notification.
Step 1
Type about:config into the Firefox address bar.
On the humorous “void your warranty” page, Click I’ll be careful, I promise!.
Step 2
In the filter box, Type missing_plugin.
Now in the preference list below, Right-Click plugins.hide_infobar_for_missing_plugin and Select Toggle.
Done!
Now when you visit a website with a plugin you don’t have installed, Firefox will no longer prompt you with the annoying “missing plugin” bar at the top of it. On my computer setup I don’t have Flash installed, so this fix comes in handy when viewing websites that have flash-based advertisements and pop-outs.

Thanks. Sounds good. But is there also a way of doing this for “incompatible extensions” in Firefox 4?

For Uninstalling and removing unwanted extension you need to:
1. On Firefox window click on the Firefox button which is at the top left and select Add-ons, or, if the Firefox button is not shown, then click on the Tools menu and click Add-ons.
2. On the Add-on Manager has opened in a new tab, then click the Extensions button on the left side of the window.
3. You get the list of installed extensions on the right side together with buttons on the right side of each extension.
4. For removing an extension from Firefox, simply click the Remove button. You should see a message that informs you about the successful removal of the add-on.

Great tip – I guess I’d also recommend doing this on a parent’s computer, to prevent them from downloading viruses.

Thank you for posting this info. I uninstalled Flash from my Mac tonight and couldn’t figure out how to turn off the missing plugin notification in Firefox. Cheers.

I didn’t quite understand this when I first feature it. Merely when I went through it a second time, it all became clear. Thanks for the brainstorm. Absolutely thing to remember just about.

Knowing that when you visit a site and in a flash (no pun) they know what is or is not in your machine is very disturbing. Thank you for valuable details.
