I received a message to update plug-ins so tried following directions, only to find out my computer is not compatible with the update. How to delete ?


I have an older iMac operating on Mac OSx 10.4. When I attempted to down-load some plug-in updates, they would not accept it because my computer is to old and doesn't have the necessary capability. When I try to remove the message, nothing works, and every time I boot the computer with Firefox, it keeps reloading. Please tell me how to delete this plug-in reminder. Thank you.

Could not find any message on the page that would offer a delete. I did note on the original page received that options were available, but I tried to up-date, and cannot get back to that page.

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
  • set the plugins.update.url pref to an empty string
