Disabling Plugins in FirefoxFiled on Oct 6, 2006 by Anthony DiSante
It bothers me when inline webpage content starts playing automatically within the browser. 99% of the time, if I want to see/hear multimedia content, I want it to be in an external player. For example, when trying to play an MP3 playlist in an M3U file, I want it to play in XMMS, not in MPlayer within Firefox.
And actually that’s how it worked until about a month ago, when some upgraded package on my Ubuntu system messed things up. Now all the M3U links that I clicked would start playing in MPlayer within Firefox... yuck.
Flashblock is a great Firefox extension that prevents all Flash content from playing unless/until you click on the content. That’s truly fantastic. But what about other types of content, like M3U? I recently learned how to prevent Firefox from launching an internal plug-in to handle any given content, instead displaying the Open/Save dialog.
Just type about:config into the address bar (and press Enter). Then type plugin.disable into the "Filter:" field. This should display something like:
...which had the following value on my system
So just double-click on that and add this to the end of the list:
Restart Firefox and presto, clicking on M3U links now displays the Open/Save dialog.
Also, if you go to the about:config page and change the value to "false" for browser.download.hide_plugins_without_extensions, then you’ll be able to control many more media types when you go to Preferences -> Content -> Manage.
