How to get Firefox to stop asking to block plugins

Hello,

Before anyone says anything, the enterprise mailing list is worthless to me. I don't need that much spam and super block quoted text.

I am attempting to customize Firefox with a deployment file (mozilla.cfg). I am using retail 23 because 17.0.8esr is too old interface-wise... even though it works for my current purpose and is my unwanted backup plan. I don't want to reduce my deployment to the 17 tree.

I have an ancient piece of software that requires java 6 jre 45 to run. Bonus is that is only works in Firefox.

However, Firefox 23 has a plugin checking utility that disables this version of java. There is a popup that states it's out of date blah blah then disabled it automatically. ( direct link to thing I am talking about - https://blog.mozilla.org/security/2012/10/11/click-to-play-plugins-blocklist-style/ )

Is there something in the mozilla.cfg file that I can add to disable this check and just let it be? I don't care if it's old and it's a security risk. I just need this software to work. There is to be no clicking of things or editing by the users... it MUST be perfect out of the box.

This thread is 6 months old, I have the same problem, and there is no resolution because this is a "new" feature. https://support.mozilla.org/en-US/questions/939323

I suspect there will be a ton of annoyed admins come 24 ESR without a good workaround. Thanks.

Thank you.

Baller. Got it from help from the googles and http://blog.mozilla.org/addons/2012/04/04/update-on-java-blocklist/

-- TLDR;

Within the installation there is a blocklist.xml

C:\program files\mozilla firefox\browser OR C:\program files(x86)\mozilla firefox\browser

That blocklist is there by default and blocks a bunch of stuff. You have two options. If you like to live dangerously just delete blocklist.xml

Else edit out all java references in blocklist.xml

For fun also add in

--


// Disabled Plugin Check defaultPref("plugin.scan.plid.all",false); defaultPref("plugins.update.url","");

// Disable plugin blocklist lockpref("extensions.blocklist.enabled", false);

--

So it doesn't actively scan or try to update. I suspect on a version update you will need to re-edit or re-delete as it's within the installer.

hello, i don't see the connection to 24 ESR - block-listing for vulnerable plugins was in the 17 ESR release already. to disable it in the mozilla.cfg refer to http://kb.mozillazine.org/Extensions.blocklist.enabled (which will you make vulnerable to malicious extensions and crashy graphics drivers though, so you'd have to keep an eye on that yourself).

See this support article over at the MoziilaZine KnowledgeBase.
http://kb.mozillazine.org/Plugin_scanning

That page was last modified on 3 June 2013, so the information is up-to-date.

You can try to set the plugin.scan.plid.all pref to false to see if that works for the Java plugin.

edit - ok I give up on formatting.. the view space is too small but everything is aligned properly in the code.

Didn't work. I read each of the replies.

For Fun here is my mozilla.cfg.

If Mozilla makes a web based html checkbox generator to spit out code, they would win enterprise. I mean I had to fight with Google Chrome too. With Chrome if one value is wrong, everything is invalidated and you're forced to reinstall. Screw that noise.

user-pref doesn't work in mozilla.cfg.

  • user_pref("plugins.update.notifyUser", false);

These functions can be used in the mozilla.cfg file:

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session
lockPref();     // lock pref, disallow changes

..where did you see user_pref? Oh. Oops. Yeah I fixed that in the code. Thanks.

You're welcome

I missed the last line with lockpref() instead of lockPref():

lockpref("extensions.blocklist.enabled", false);

This website says I need a plugin when I don't have the issue with CHROME or IE.

I changed something once in about:config but don't remember what I did to get around this problem.

Anyone have any idea?

THANKS.

Hi FOXYSTORMIN

That page uses the Flash plugin.
You can check if there is a plugin block icon on the left hand side of the location (address) bar that indicates that Firefox is blocking plugins.

You can click this icon to enable the Flash plugin.

1st reply:

Thanks for the tip, but it didn't help. There IS some change in about:config that worked last time, but I can't remember what it us.

UPDATE: GOT it to work! I never had a PLUGIN for WMP but I do now. The one that is now in the ADD-ON Section says it is for Firefox 1.1, but, who cares: it works!

Thanks.

FS

Thanx for explaining how you got it to work. Usually the way things are done in IT, but you know... Kids are pretty stupid these days! :D
