Hi vedangshrimankar, Thank you for your question. Where is this: Cc["@mozilla.org/plugin/host;1"]? are you building Firefox with plugins?

I do know that the extensions in about:config are listed here, some are outdated: http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entrie...

There is a plugin.default.state

I will ask on irc and check back shortly.

Cheers, I confirmed that they do need more information on what you are trying to do. http://mxr.mozilla.org/mozilla-centra.../host this search confirms it should work in the build.

Looking forward to your reply!

Cc["@mozilla.org/plugin/host;1"] still works in the Browser Console (Firefox/Tools > Web Developer), but I don't know what functions and methods this interface provides.

• nsJSCID {name: "@mozilla.org/plugin/host;1", number: "{23e8fd98-a625-4b08-be1a-f7cc18a5b106}", valid: true}

So you would have to give more details and if this is about code in an extension then you may have to ask elsewhere.

Thanks for your reply, Cc["@mozilla.org/plugin/host;1"] provides many functions like, plugin.name, plugin.description, plugin.disabled.

plugin.name and plugin.description are read only. In FF28 we can disable the plugin using plugin.disabled=true.

But in FF29 or 30 it can't work so i think this may also be read only in 29 and 30.

So, what is the solution to disable installed plugin in 29 or 30?

Thanks in advance.

HI ,

Finally got the solution.

plugin.enabledState=0

See:

• resource://gre/modules/addons/PluginProvider.jsm

    let tags = Cc["@mozilla.org/plugin/host;1"].
               getService(Ci.nsIPluginHost).
               getPluginTags({});

    for (let tag of aTags) {
      if (aVal === true)
        tag.enabledState = Ci.nsIPluginTag.STATE_DISABLED;
      else if (aVal === false)
        tag.enabledState = Ci.nsIPluginTag.STATE_ENABLED;
      else if (aVal == AddonManager.STATE_ASK_TO_ACTIVATE)
        tag.enabledState = Ci.nsIPluginTag.STATE_CLICKTOPLAY;
    }

HI vedangshrimankar, We are happy that you came to a solution. At this time we are doing an investigation on an add on called V-Bates as it is a culprit to a number of crashes in this new version. If you have a copy of these files: "DLL file (probably named libinject2.dll, libredir2.dll or nptnt2.dll). We're trying to get copies of this DLL as well as the version number (from Add/Remove programs) of V-Bates." rmcguigan@mozilla.com
