Disable plugin update check

Hi, We are using firefox on centos linux on around 1000 computers. We are using Firefox 10.0.7 ESR. For our applications we need JRE1.6_17.

The problem is, that some of our intranet pages stopped working. I found out, that java plugin was disabled. It was disabled because the user clicked yes when asked that the plugin was old and it will be disabled.

I tried changing "plugins.update.url" in about:config, but firefox still found,that the plugin was old.

So my questio would be: Is there a way to disable plugin checking (at least for java plugin) in about:config or using some config file?

I know it is possible to do this by clicking, but if someone wants to do this on 1000 computers using multiple user profiles with the machines spread acrosss 500 kilometers, please contact me.

Re: Disable plugin update check

You will probably need to disable blocklisting and delete the current blocklist.xml file to avoid plugins from getting blocked.
That is not really recommended, so be cautious with making such a change.

Everytime you upgrade Firefox, it will do a addon update check.

before you upgrade to the new Firefox version.. Modify the prefs.js or user.js file in the logged on users firefox profile .

There may be one or both of these lines already in the prefs.js file.

currect version installed 10.0.3:

user_pref("extensions.lastAppVersion", "10.0.3"); user_pref("extensions.lastPlatformVersion", "10.0.3");

Modify the prefs.js or user.js

Installing version 15.0.1:

user_pref("extensions.lastAppVersion", "15.0.1"); user_pref("extensions.lastPlatformVersion", "15.0.1");

modify this to the version you are going to install before you do the install.

The above suggestion was great, but it didn't work. Users are still being prompted to choose add-ons when they run Firefox.
