(Toolkit Graveyard :: Plugin Finder Service, defect)

this came up because I wanted to make the helper toolbar "install plugin now" gizmo never come up, on flash pages. I installed flashblock... but it still sometimes comes up.

someone pointed out that that toolbar comes up because of the "default plugin" trying to help me find and download the right plugin. However.. it is supposedly DISABLED!

about:plugins, says

Default Plugin

    File name: libnullplugin.so
    The default plugin handles plugin data for mimetypes and extensions that are not specified and facilitates downloading of new plugins.

MIME Type 	Description 	Suffixes 	Enabled
* 	       All types 	.* 	           No


Note: I didnt put this in the "plugin finder service" category.. because it's not the "finding" thats broken. it would seem to be the more general "assignment of mime types to a plugin" functionality, which is more core to the browser.




Reproducible: Sometimes

Steps to Reproduce:
go find a forum or something that has a plugin type you dont have installed (eg: shockwave), and go browse around the pages, it should eventually pop it up .


Actual Results:  
sometimes, the toolbar downloader thing gets inserted at top of a page.


Expected Results:  
no toolbar insert thing at top of the page

It's on All OS.
I think "Enabled: No" doesn't mean the default plugin will not be used.

You can just delete libnullplugin.so, if you don't like it.

well, i cant just delete it, because it's part of an NFS_shared install of the browser.

I'd like to be able to PROPERLY disable the default plugin.

oops, I think we misunderstood what "Enabled: No" mean for default plugin.
The default plugin is disabled by default so that plugin finder will work.

If you want to stop "additional plugins are required ...", you can just enable the default plugin.
In about:config, change "plugin.default_plugin_disabled" to false.

The trouble with that, is that it then makes a popup.

"The type of application... blah blah... click OK to download plugin".


So, depending on my setting of "default_plugin_disabled", i have a choice of using the plugin finder... or using the plugin finder !
the only difference being that one way, there is an "in-window" button to click,
and the other way there is a popup window to click.

Isnt there a setting for "SHUT THE ... UP and just ignore it!" that doesnt require me "deleting" files from a firefox distribution?

Removing libnullplugin.so no longer seems to make that install bar go away.  Is there some other mechanism now?  How do I shut THAT off?  Bug #261751 gives the impression that there is some other mechanism.  I'm using 2.0.6, just upgraded from (I think) 1.5.0.7.

Until FF3 you could set plugin.default_plugin_disabled to false and it would suppress the popup. But now, that doesn't work. And if you set it to true, you get the nag bar, which isn't quite as annoying but still a problem.

So how do you suppress all plugin nagging in FF3? If it's not possible, maybe a new bug should be filed?

the libnullplugin is gone and there is plugins.hide_infobar_for_missing_plugin
