How do I disable the "some plugins are out of date" message


I am running firefox 3.6.3 on a powerpc mac laptop. There are no more upgrades to either firefox or any of the plugins it is using. It's a powerpc and the current updates of the plugins all require an intel based mac. I constantly get the message "some plugins used by this page are out of date" message above the screen, or Firefox disables plugins because it says they are a security risk. I don't care. This is an old computer that would work fine if Firefox would just stop trying to upgrade either itself or its plugins, or try to warn me about something that can't be upgraded and that I don't care about. MAC rule number one: The user is in charge. How do I fix this annoying and PC like feature?

In the future if Firefox is going to continue to have this "feature" it should keep track of what kind of computer it is running on and what what updates can and can not run on the computer it is running on, or give the user the option of turning off not only the messages but the whole plugin update function.

Firefox 3.6.28 was the last version of Firefox for PPC Macs, not the 3.6.3 version you now have.

For older Macs that aren't supported in the Firefox 4+ versions, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .

I'm not sure what you mean Address bar > Plugins

In addition, the whole issue of forcing an update is crap. There are other programs that may be using those same plugins, and a user may many times not want to update a plugin due to compatibility issues with other apps. To constantly see this message is annoying, and I even tried to get google chrome at one point I was so annoyed. General rule, when you've got a stable system, don't screw with it.

What is meant in to open the "Tools > Add-ons > Plugins" window (the about:addons page doesn't exist in Firefox 3.6.x)

You can inspect and modify some prefs on the about:config page to suppress the plugin reminder.

  • set the plugins.hide_infobar_for_missing_plugin pref to true
  • set the plugins.hide_infobar_for_outdated_plugin pref to true

I'm on a mac, so what your talking about doesn't exist in that form. However in the user/library/application support/firefox there is a prefs.js file that contains some user pref data, but not the specific ones you mention. I see other files that relate to addons, but no contain a popup preference.

Any other thoughts?

Prefs that have the default value do not show up in the prefs.js file.
You need to change (toggle) them on the about:config page.

Type about:config in the location (address) bar and press the "Enter" key to open the about:config page, just like you open a website by typing the URL in the location bar.

  • If you see a warning message then you can confirm that you want to access the about:config page.
  • use the Search bar at the top of the about:config page to locate preferences more easily
  • preferences that have been modified and do not have the default value show as bold (user set)
  • preferences that are user set (bold) can be reset to the default value via the right-click context menu
  • preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean) or by double-clicking the line with the pref
  • preferences can be created via the right-click context menu: New -> String, Integer, Boolean
